Subject: Amendment No. 1 to the Climate Action Plan
Recommended Action
Adopt a resolution approving an amendment to the Climate Action Plan to revise the
greenhouse gas inventory and reduction targets and forecast, update reductions from existing
measures and incorporate Community Choice Energy as a new reduction measure.
Executive Summary
The City Council received an informational presentation on April 14, 2020, on the status of the
Climate Action Plan and efforts to adjust the greenhouse gas emission reductions to reach the
2035 targets. This proposed amendment to the plan, known as CAP, would implement those
efforts by revising the greenhouse gas inventory and reduction targets and forecast, updating
reductions from existing measures and incorporating Community Choice Energy as a new
reduction measure. To analyze potential environmental impacts with the CAP amendment, staff
prepared an addendum to the General Plan Update and CAP Final Program Environmental
Impact Report consistent with the California Environmental Quality Act Guidelines.
Discussion
The Climate Action Plan’s purpose is to describe how greenhouse gas emissions within the City
of Carlsbad will be reduced in accordance with statewide targets through the implementation
of certain measures.1 These measures were based upon the greenhouse gas inventory, targets
and forecasts contained in the CAP.
In its informational presentation on the CAP and vehicle miles traveled calculations to the
council in January, staff noted there had been an error in the vehicle miles traveled calculations
used for the original CAP greenhouse gas inventory, which necessitated an amendment to the
CAP. On April 14, 2020, staff presented a progress report to the City Council on amending the
CAP through establishment of a 2012 greenhouse gas inventory, recalculation of greenhouse
gas emissions targets and forecasts and incorporation of Community Choice Energy as a CAP
measure.
1 The plan was approved by the City Council in 2015 through resolution nos. 2015‐242 and 2015‐244 along with the
General Plan Update and the associated environmental impact report.
July 14, 2020 Item #17 Page 1 of 128
Since the adoption of the CAP, the California Air Resources Board has issued the 2017 Climate
Change Scoping Plan which contains updated guidance on calculating greenhouse gas reduction
targets. State and federal policies affecting greenhouse gas reduction efforts have also
changed. As staff noted in the April 14 presentation, Community Choice Energy must be added
as a CAP greenhouse gas reduction measure to reach the updated targets. The proposed CAP
Amendment addresses all these changed circumstances.
Specifically, the CAP Amendment would:
Revise Chapter 1 – “Introduction” with updated background information on global
temperatures and state and federal legislation and regulations
Revise Chapter 2, Section 2.1 – “Methodology” with information on the derivation of
the 2012 inventory
Revise Chapter 2, Section 2.2 – “Community Inventory” by replacing the 2005 and 2011
greenhouse gas inventories with a 2012 inventory
Revise Chapter 3 – “Greenhouse Gas Reduction Target, Forecasts, and Emissions ‘Gap’”
as follows:
o Revise Section 3.1 – “Greenhouse Gas Reduction Target” with updated
information on the California Air Resources Board Scoping Plan guidance
o Revised Table 3‐1 – “2005 Emissions and Emissions Targets” with 2012 emissions
and Scoping Plan derived targets
o Revise Sections 3.2 through 3.7 in accordance with the 2012 inventory, Scoping
Plan derived targets, and updated forecast
Revise Chapter 4 – “CAP Greenhouse Gas Reduction Measures” as follows:
o Revise Sections 4.1 through 4.11 by replacing the content of the tables
containing Goals, 2035 Reductions and Actions for all measures with new
reductions and updated Actions
o Delete Measures A, C and H
o Add a section for the Community Choice Energy measure (Measure P)
o Revise existing Section 4.12 – “Combined Effect of CAP Greenhouse Gas
Reduction Measures and Forecast with CAP” to include updated text, revise
Table 4‐1 – “CAP Greenhouse Gas Reduction Measures Summary,” delete Tables
4‐2 and 4‐3, and update Figure 4‐1 – “Forecast Community Emissions with CAP
Reduction Measures and Targets.”
Revise and retitle Appendix B‐1 – “2005 City of Carlsbad Greenhouse Gas Inventory” by
replacing the entire appendix with the 2012 greenhouse gas inventory
Revise and retitle Appendix B‐2 – “2011 Carlsbad Community and Local Government
Operations Greenhouse Gas Inventory Updates” by deleting Community greenhouse gas
information on pages 1 through 10
These revisions to the existing CAP will allow the city to meet its 2020 and 2035 greenhouse gas
reduction targets and enable the plan to be considered a qualified climate action plan under
the California Environmental Quality Act and used to streamline the permit streamlining
through discretionary project environmental review.
July 14, 2020 Item #17 Page 2 of 128
Fiscal Analysis
This Climate Action Plan amendment contains administrative changes to the CAP, such as
revising the greenhouse gas inventory, targets and forecast and inclusion of Community Choice
Energy as a new reduction measure. Monitoring of Community Choice Energy implementation
will be accommodated through the existing CAP annual reporting process, without need for
additional personnel. No new programs are needed to administer the proposed CAP
Amendment so there are no fiscal impacts associated with the recommended action.
Next Steps
Staff will coordinate with the Clean Energy Alliance Joint Powers Authority to monitor
implementation of the Community Choice Energy and return to the City Council in fall 2020
with the Climate Action Plan Annual Report for Reporting Year 4 (fiscal year 2019‐20). Staff will
also pursue a CAP update to address changes to forecasted emissions due to the upcoming
General Plan Housing Element Update. It is anticipated that this CAP update will be presented
to the City Council in spring 2021.
Environmental Evaluation (CEQA)
The CAP was previously evaluated in the General Plan Update and Climate Action Plan Final
Program Environmental Impact Report (13‐02), dated June 15, 2015. This report evaluated the
potential environmental effects of implementing the greenhouse gas reduction measures
contained in the CAP. The addition of Community Choice Energy as a measure necessitates
further review of potential environmental impacts.
In keeping with California Environmental Quality Act Guidelines Section 15164, an addendum to
the final program environmental impact report was prepared and is attached as Exhibit 2. The
addendum showed that none of the changes contained in CAP Amendment No. 1 meets the
standards required for a subsequent environmental impact report, which are contained in
CEQA Guidelines Section 15162. The addendum also demonstrates that CAP Amendment No. 1
will not result in any potentially significant impacts to the environment. According to CEQA
Guidelines Section 15164(c), the addendum does not require circulation for public review.
Public Notification and Outreach
Public notice of this item was posted in accordance with the Ralph M. Brown Act and it was
available for public viewing and review at least 72 hours prior to scheduled meeting date.

Introduction
1.1 Scope and Purpose
Background and Purpose
The Climate Action Plan (CAP) is designed to reduce Carlsbad’s greenhouse gas (GHG)
emissions and streamline environmental review of future development projects in the city in
accordance with the California Environmental Quality Act (CEQA).
The original CAP, adopted in September 2015, has beenwas prepared concurrently with the
city’s updated General Plan and includesd actions to carry out the General Plan’s goals and
policies, consistent with the Community Vision articulated during Envision Carlsbad. The
original CAP iswas also correlated with the Environmental Impact Report (EIR) on the General
Plan, with the CAP GHG reduction target synchronized with the EIR. CAP Amendment No.
1, adopted in May 2020, revised the greenhouse gas inventory, reduction targets and forecast,
updated reductions from existing measures, and incorporated Community Choice Energy as a
new reduction measure (Measure P). An Addendum to the EIR was also prepared.
Community Vision and Environmental Stewardship
Carlsbad has long been a steward of environmental sustainability. In 2007, the Carlsbad City
Council adopted a set of sustainability and environmental guiding principles (Resolution No.
2007-187) to help guide city investments, activities, and programs. Sustainability emerged as
a key theme during the Envision Carlsbad community outreach process, and reflected as a Core
Value of the Community Vision:
Core Value 6: Sustainability. Build on the city’s sustainability initiatives to emerge as
a leader in green development and sustainability. Pursue public/private partnerships,
particularly on sustainable water, energy, recycling, and foods.
The General Plan
The General Plan includes strategies such as mixed-use development, higher density infill
development, integrated transportation and land use planning, promotion of bicycle and
pedestrian movements, and transportation demand management. It also includes goals and
policies to promote energy efficiency, waste reduction, and resource conservation and

1: INTRODUCTION
recycling. These strategies, goals, and policies would result in GHG reduction compared to
baseline trends.
CAP
The CAP includes goals, policies, and actions for Carlsbad to reduce GHG emissions and
combat climate change and includes:
An inventory of Carlsbad’s citywide and local government GHG emissions;
Forecasts of future citywide and local government GHG emissions;
A comprehensive, citywide strategy and actions to manage and reduce GHG emissions,
with emission targets through 2035; and
Actions that demonstrate Carlsbad’s commitment to achieve state GHG reduction targets
by creating enforceable measures, and monitoring and reporting processes to ensure
targets are met.
The timeframe for the Plan extends from the date of adoption through 2035.
1.2 Climate Change and Greenhouse Gases Overview
Greenhouse Effect and GHGs
Gases that trap heat in the atmosphere are often called “greenhouse gases” (GHGs). The
greenhouse effect traps heat in the troposphere through a threefold process as follows: Short-
wave radiation emitted by the sun is absorbed by the earth; the earth emits a portion of this
energy in the form of long-wave radiation; and GHGs in the upper atmosphere absorb this
long-wave radiation, emitting some of it into space and the rest back toward the earth. This
“trapping” of the long-wave (thermal) radiation emitted back toward the earth is the underlying
process of the greenhouse effect (Figure 1-1).
Principal GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone
(O3), and water vapor (H2O). Some GHGs, such as CO2, CH4, and N2O, occur naturally and
are emitted to the atmosphere through natural processes and human activities. Since different
gases contribute to the greenhouse effect in different proportions, the term CO2e (carbon
dioxide equivalent) provides the reference frame based on comparison to CO2’s contribution.
The greenhouse effect is a natural process that contributes to regulating the earth’s temperature.
Without it, the temperature of the earth would be about 0°F (−18°C) instead of its present 57°F
(14°C) and unlikely to support human life in its current form.

Carbon Cycle and Global Temperatures
The global carbon cycle is complex and incorporates natural sources of atmospheric carbon
dioxide, including respiration of aerobic organisms, wildfires, and volcanic outgassing, and
sinks such the removal of CO2 from by land plants for photosynthesis, and absorption by the
ocean. Data collected on global GHG concentrations over the past 800,000 years demonstrates
that the concentration of CO2, the principal GHG, has increased dramatically since pre-
industrial times, from approximately below 300 parts per million (ppm) in 1800, to about 353
ppm in 1990, 379 ppm in 2005, and 399 ppm in early 2013407 in 2018.1
Increased atmospheric concentrations of GHGs have led to a rise in average global
temperatures. Figure 1-2 shows the increase in global temperatures from 1880 to 20112019.
While average global temperatures fluctuate on a yearly basis, the general trend shows a long-
term temperature increase. Nine All of the ten warmest years since 1880 have occurred since
the year 2000, and scientists expect the long-term temperature increase to continue as well.
The consensus among climate scientists is that earth’s climate system is unequivocally

Climate Change
Global climate change concerns are focused on the potential effects of climate change resulting
from excessive GHGs in the atmosphere and how communities can mitigate effects and adapt
to change in the short and long term.
Numerous observations document the impacts of global climate change, including increases in
global average air and ocean temperatures, the widespread melting of snow and ice, more
intense heat waves, and rising global average sea level. Scientists have high confidence that
global temperatures will continue to rise in the foreseeable future, largely due to anthropogenic
GHG emissions. In addition to the physical impacts to the environment from increased
temperatures, sea level rise, and more frequent extreme weather events, global climate change
is predicted to continue to cause ecological and social impacts. Ecological impacts of climate
change include greater risk of extinction of species, loss of species diversity, and alteration of
global biogeochemical cycles, which play an essential role in nutrient distribution. The social
impacts of climate change include impacts on agriculture, fisheries, energy, water resources,
forestry, construction, insurance, financial services, tourism and recreation.
According to the International Panel on Climate Change (IPCC) in North America, the regional
impacts of climate change are a forecast of decreased snowpack in the western mountains, a 5
to 20 percent decrease in the yields of rain-fed agriculture in some regions, and increased
frequency, intensity and duration of heat waves in cities that currently experience them.
In California, the Climate Action Team (CAT)—a group of state agency secretaries and the
heads of agency, boards and departments, led by the Secretary of the California Environmental
Protection Agency—synthesized current research on the environmental and economic impacts
of climate change. The CAT found that climate changes are poised to affect virtually every
sector of the state’s economy and most ecosystems. Key findings of the CAT include predicted
decreases in water supply that could cause revenue losses of up to $3 billion in the agricultural
sector by 2050, increases in statewide electricity demand of up to 55 percent by the end of the
century, increased wildfire risk that may cause monetary impacts of up to $2 billion by 2050,
and ecosystems impacts affecting California’s historic ranching culture and a source of local,
grass-fed beef.
Higher temperatures, changes in precipitation, decreased water supplies accompanied by
increased demand, increased risk of wildfire, a greater number of extremely hot days, the
decline or loss of plant and animal species, and other impacts of climate change are expected
to continue to affect Carlsbad. Climate change also has public health impacts. City residents
who are already more vulnerable to health challenges are likely to be the most affected by
climate change. These populations tend to be the young and the old, the poor, and those who
are already sick. Increases in extreme heat events can increase the risk of heat-related illness
or death, or the worsening of chronic health conditions. Food scarcity and higher food prices
from impacts to agriculture can cause increased hunger and reduced availability of nutrition.
The increased frequency of natural disasters such as floods, droughts, wildfires, and storm
surges can cause injury or death, illness, and increases or shifts in infectious diseases.

1: INTRODUCTION
1.3 California GHG Reduction Legal Framework
California has taken an aggressive stance to reduce GHG emissions in order to combat the
impacts of climate change.
Governor’s Executive Order S-3-05
Executive Order S-3-05 (EO S-3-05) recognizes California’s vulnerability to increased
temperatures causing human health impacts, rising sea levels, and reduced Sierra snowpack
due to a changing climate. The Executive Order established targets to reduce GHG emissions
to 2000 levels by 2010, to 1990 levels by 2020, and to 80 percent below 1990 levels by 2050.
Global Warming Solutions Act of 2006 and CARB Scoping Plans
The Global Warming Solutions Act of 2006 (Assembly Bill 32, or AB 32) codifies the target
set in EO S-3-05 of statewide reductions to 1990 emissions levels by 2020. AB 32 directs the
California Air Resources Board (CARB) to develop and implement a scoping plan and
regulations to meet the 2020 target.
CARB approved the first Scoping Plan in 2008, which providesd guidance for local
communities to meet AB 32 and EO S-3-05 targets. The Scoping Plan adopted a quantified cap
on GHG emission representing 1990 emission levels, instituted a schedule to meet the emission
cap, and developed tracking, reporting, and enforcement tools to assist the State in meeting the
required GHG emission reductions. The Scoping Plan recommends that local governments
target 2020 emissions at 15 percent below 2005 levels to account for emissions growth since
1990, as proxy for 1990 emissions, since few localities know those levels.California is
currently on track to meet or exceed the AB 32 target of reducing GHG emissions to 1990
levels by 2020.
Executive Order B-3015 (EO B-30-15) established a new GHG emissions reduction target of
40 percent below 1990 levels by 2030 and directed CARB to update the Scoping Plan. In
September 2016, Senate Bill 32 (SB 32) was signed into law and codified EO B-30-15. In
November 2017, CARB published the 2017 Climate Change Scoping Plan, which offers the
framework for achieving the 2030 reductions set forth in EO B-30-15 and SB 32.
The Carlsbad CAP’s GHG emission targets are based on meeting the goals set in EO S-3-05
and AB 32.
1.4 Federal and State Emissions Reductions Strategies
and Standards
Several federal and state standards have been adopted to reduce GHG emissions, in addition to
and in support of the targets set in EO S-3-05 and AB 32.
July 14, 2020 Item #17 Page 11 of 128
Federal Standards
The United States Environmental Protection Agency (EPA) regulates and tests gas mileage or
fuel economy in order to deter air pollution in the United States. As the transportation sector
produces approximately 30 percent of GHG emissions in the U.S. as a whole, fuel economy
regulations are an important way to reduce GHG emissions.3 The EPA’s Corporate Average
Fuel Economy (CAFE) standards require vehicle manufacturers to comply with the gas
mileage or fuel economy standards to reduce energy consumption by increasing the fuel
economy of cars and light trucks. The most recent CAFE GHG emissions standards were set
in 2012, which will increase the fuel economy to 54.5 miles per gallon average for cars and
light trucks by Model Year 2025, and reduce U.S. oil consumption by 12 billion barrels per
year. The EPA also imposes the Gas Guzzler Tax on manufacturers of new cars that do not
meet required fuel economy levels, to discourage the production and purchase of fuel-
inefficient vehicles. Also, in 2007, the U.S. Supreme Court ruled that CO2 is an air pollutant
under the Federal Clean Air Act, confirming that the EPA can regulate GHG emissions.
The EPA is taking further action to reduce GHG emissions in addition to setting fuel economy
standards. The EPA established a renewable fuel standard to include a minimum volume of
renewable fuel in 2013, which applies to all gasoline and diesel produced or imported. On
September 20, 2013, the EPA proposed the first national limits on the amount of carbon
pollution that new power plants will be allowed to emit. The EPA will propose standards for
existing power plants by June 1, 2014. The EPA also approved oil and natural gas air pollution
standards in 2013 to reduce pollution from the oil and natural gas industry.
State Standards
California Senate Bill 375
SB 375 (2008) requires each Metropolitan Planning Organization (MPO) in the state to adopt
a Regional Transportation Plan (RTP) aimed at achieving a coordinated and balance regional
transportation system, including mass transit, highways, railroads, bicycles, and pedestrians,
among other forms of transit. Each MPO is required to prepare a Sustainable Communities
Strategy (SCS) which sets forth forecast development patterns and describes the transportation
system that achieve the regional GHG emission reduction targets set by CARB.
CARB’s targets for San Diego County call for the region to reduce per capita emissions 7
percent by 2020 and 13 percent by 2035 based on a 2005 baseline. There are no mandated
targets beyond 2035. San Diego Association of Governments (SANDAG), the San Diego
County MPO, adopted its current RTP/SCS in October 2011. The SCS lays out how the region
will meet the CARB GHG targets to the year 2035. As the SCS is focused on passenger vehicle
emissions on a regional scale, it is considered separate from the reductions outlined in this
CAP.
3 In 2011, GHG emissions from transportation were about 28 percent of the total 6,702 million metric tons CO2
equivalents (Source: https://www.epa.gov/ghgemissions/sources-greenhouse-gas-
emissionshttp://www.epa.gov/climatechange/ghgemissions/sources/transportation.html)
July 14, 2020 Item #17 Page 12 of 128
1: INTRODUCTION
Senate Bill 1368
SB 1368 creates GHG emissions performance standards for baseload generation4 from
investor-owned utilities. The bill requires that any long-term financial investment in baseload
generation resources made on behalf of California customers must meet a performance
standard of producing below 1,000 lbs CO2 per MWh (megawatt-hour), approximately equal
to a combined-cycle natural gas plant.
Governor’s Executive Order S-1-07 (Low Carbon Fuel Standard)
Executive Order S-1-07, the Low Carbon Fuel Standard (LCFS), requires a reduction of at least
10 percent in the carbon intensity of California’s transportation fuels by 2020. The LCFS
requires oil refineries and distributors to ensure that the mix of fuel sold in California meets
this reduction. The reduction includes not only tailpipe emissions but also all other associated
emissions from the production distribution and use of transport fuels within the state.
Renewable Portfolio Standards
California’s Renewable Portfolio Standard (RPS), established in 2002 by the California State
Senate in Senate Bill 1078, accelerated in 2006 and expanded in 2011 through SB X1-2, is one
of the most ambitious renewable energy standards in the country. The RPS requires each
energy provider to supply electricity from eligible renewable energy resources to 33 percent of
the total supply by 2020. In 2015, SB 350 increased the RPS to 50 percent renewable by 2030
and a doubling of energy savings in electricity and natural gas customers. In 2018, SB 100
updated SB X1-2 and requires 100 percent of electric retail sales and 100 percent of electricity
procured to serve state agencies be carbon-free by 2045.
Pavley Fuel Economy Standards (AB 1493)
In 2009, CARB adopted amendments to the Pavley regulations to reduce GHG emissions in
new passenger vehicles from 2009 to 2016. The standards became the model for the updated
federal CAFE standards.
Title 24 Building Standards & CALGreen
Title 24 is California’s Building Energy Code, which is updated every three years. In 2010,
Title 24 was updated to include the “California Green Building Standards Code,” referred to
as CALGreen. CALGreen requires that new buildings reduce water consumption, increase
system efficiencies, divert construction waste from landfills, and install low pollutant-emitting
finish materials. CALGreen has mandatory measures that apply to nonresidential and
residential construction. The most recent CALGreen code was adopted in 20139 and became
effective in 201420. CALGreen contains voluntary Tier 1 and Tier 2 levels, which are designed
to exceed energy efficiency and other standards by 15 percent or 30 percent.
4 Baseload generation is the minimum amount of power that a utility must make available to customers to meet minimum
demands based on customer usage.

1.5 Planning Process
How This Plan Was Prepared
The CAP reflects the city’s commitment to the Core Values presented in the General Plan, and
links the elements of the plan—including Sustainability; Open Space and the Natural
Environment; Access to Recreation and Active, Health Lifestyles; Walking, Biking, Public
Transportation, and Connectivity; and Neighborhood Revitalization, Community Design, and
Livability—with the goal of GHG reduction. The original CAP was prepared in 2013 by City
staff and consultants, with input from the public.
On August 22, 2013 the City of Carlsbad hosted a Community Workshop on the CAP. The
workshop provided an opportunity to present the citywide emissions inventory that had been
completed, and discuss potential emission reduction strategies. Feedback from the Community
Workshop was used to guide the preparation of this document.
Relationship to the California Environmental Quality Act
The California Environmental Quality Act (CEQA) is a statute that requires local agencies to
identify significant environmental impacts of their actions and avoid or mitigate those impacts,
if feasible. In 2007, California’s lawmakers enacted Senate Bill (SB) 97, which expressly
recognizes the need to analyze GHG emissions as part of the CEQA process. SB 97 required
the Governor’s Office of Planning and Research (OPR) to develop recommended amendments
to address GHG emissions as an environmental effect.
In 2010, OPR’s amendments to the CEQA guidelines addressing GHG emissions became
effective. Lead agencies are now obligated to describe, calculate or estimate the amount of
GHG emissions resulting from a project, by using a model or methodology to quantify GHG
emissions resulting from a project or relying on a qualitative analysis or performance
basedperformance-based standards. The lead agency should determine whether a project’s
GHG emissions significantly affect the environment by considering whether the project’s
emissions, as compared to the existing environmental setting, exceeds a threshold of
significance that the lead agency determines applies to the project, and the extent to which the
project complies with the regulations or requirements adopted to implement a statewide,
regional, or local plan for the reduction or mitigation of GHG emissions. In addition, the lead
agency is required to impose feasible mitigation to eliminate or substantially reduce significant
effects.
The CAP will help the city with compliance with CEQA Guidelines Section 15183.5(b):
Tiering and Streamlining the Analysis of Greenhouse Gas Emissions, which became effective
in 2010.5 The required elements of a CAP, as cited in the guidelines, state that a plan for the
reduction of GHG emissions should:
5 15183.5(b) of CEQA Guidelines states, “Plans for the Reduction of Greenhouse Gas Emissions. Public agencies may
choose to analyze and mitigate significant greenhouse gas emissions in a plan for the reduction of greenhouse gas emissions or similar document. A plan to reduce greenhouse gas emissions may be used in a cumulative impacts
analysis as set forth below. Pursuant to sections 15064(h)(3) and 15130(d), a lead agency may determine that a
July 14, 2020 Item #17 Page 14 of 128
1: INTRODUCTION
Quantify greenhouse gas emissions, both existing and projected over a specified time
period, resulting from activities within a defined geographic area;
Establish a level, based on substantial evidence, below which the contribution to
greenhouse gas emissions from activities covered by the plan would not be cumulatively
considerable;
Identify and analyze the greenhouse gas emissions resulting from specific actions or
categories of actions anticipated within the geographic area;
Specify measures or a group of measures, including performance standards, that
substantial evidence demonstrates, if implemented on a project-by-project basis, would
collectively achieve the specified emissions level;
Establish a mechanism to monitor the plan’s progress toward achieving the level and to
require amendment if the plan is not achieving specified levels;
Be adopted in a public process following environmental review.
The CAP is intended to fulfill these requirements. The CAP also contains a Project Review
Checklist, which allows for streamlined review of GHG emissions for projects that demonstrate
consistency with the CAP, as described in CEQA Guidelines Section 15183.5(b).
Relationship to General Plan and Future Projects
Carlsbad’s approach to addressing GHG emissions within the General Plan is parallel to the
climate change planning process followed by numerous California jurisdictions. A General
Plan is a project under CEQA, and projects under CEQA are required to estimate CO2 and other
GHG emissions, as described above. According to the Attorney General, “in the context of a
general plan update, relevant emissions include those from government operations, as well as
from the local community as a whole. Emissions sources include, for example, transportation,
industrial facilities and equipment, residential and commercial development, agriculture, and
land conversion.” The CAP is designed to provide discrete actions to operationalize the General
Plan policies that help with GHG reduction, as well as outline additional actions to help meet
GHG reduction targets. The preparation of a CAP is also consistent with CEQA Guidelines
Section 15183.5 that allows jurisdictions to analyze and mitigate the significant effects of GHG
at a programmatic level, by adopting a plan to reduce GHG emissions.
Project-specific environmental documents prepared for projects consistent with the General
Plan may rely on the programmatic analysis contained in the CAP and the EIR certified for the
Carlsbad General Plan. The thresholds presented in Section 5.3 present a clear method for
determining the significance of GHG emissions for future projects.
project’s incremental contribution to a cumulative effect is not cumulatively considerable if the project complies with
the requirements in a previously adopted plan or mitigation program under specified circumstances.”

1.6 How to Use This Plan
The CAP is intended to be a tool for policy makers, community members and others to guide
the implementation of actions that limit Carlsbad’s GHG emissions. Ensuring that the
mitigation measures in the CAP translate from policy language to on-the-ground results is
critical to the success of the CAP. Chapter 5 describes how the city will review development
projects to achieve the GHG reduction measures in Chapter 4, consistent with state CEQA
Guidelines. This chapter also outlines how the city will monitor progress in reducing emissions,
and periodically revisit assumptions and key provisions of the plan.

Emissions Inventory
This chapter identifies the major sources and the overall magnitude of greenhouse gas (GHG)
emissions in Carlsbad, pursuant to Sections 15183.5(b)(1)(A) and 15183.5(b)(1)(C) of the state
CEQA Guidelines. The City of Carlsbad prepared an inventory of 2005 for communitywide
GHG emissions in 2012, 2014 and 2016, the latter of which was provided through the San
Diego Association of Government’s (SANDAG) Regional Climate Action Planning (ReCAP)
program. The city also prepared a 2005 and 2011 inventory of, including emissions from
government operations, in 2008. As part of the Climate Action Plan (CAP) preparation effort,
this inventory was updated to 2011 to provide a more current measure of emissions, and is
summarized in this chapter. Appendix B-1 provides the 2005 communitywide inventoriesy and
2011 update in detail and Appendix B-2 contains the government operations inventories, both
of, which areis summarized in Section 2.2 and 2.3 in this chapter, respectively.
The inventory follows the standards developed by the International Council for Local
Environmental Initiatives (ICLEI) for community and government operations GHG
inventories. The inventory methodology is described first, followed by the inputs, and results.
2.1 Methodology
The community inventoriesy covers all direct GHG emissions6 from sources within the
boundaries of the City of Carlsbad, including fuel combusted in the community and direct
emissions from landfills within the community. Indirect emissions associated with the
consumption of energy (such as electricity, with no end point emissions) that is generated
outside the borders of the city are also included. The U.S Community Protocol for Accounting
and Reporting of Greenhouse Gas Emissions (U.S. Community Protocol), published by ICLEI
USA, requires a minimum of five basic emissions-generating activities to be included in
Protocol-compliance community-scale inventories. The emissions from off-road transportation
(e.g. lawn and garden, construction and industrial equipment) are considered in the inventories.
The community inventory tallies emissions from six seven emissions-generating activities
included in the community inventories are:
6 GHGs considered in the report are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons.
The emissions have been converted to carbon dioxide equivalents (CO2e), which converts the three other GHGs into
the equivalent volume of carbon dioxide.

As the city has much greater ability to influence its own operations, the government operations
inventory is presented separately, and covers direct emissions from sources the City of
Carlsbad owns and/or controls. This includes mobile combustion of fuel for city vehicles and
the use of natural gas to heat city buildings. Indirect emissions associated with the consumption
of electricity, steam, heating or cooling for city operations that are purchased from an outside
utility are also included. All other indirect emissions sources, including employee commutes
and the decomposition of government-generated solid waste, are not included as part of the
local government operations, but rather counted in the community inventory. The government
operations inventory covers emissions from the following sectors:
Buildings and Facilities;
Vehicle Fleet;
Public Lighting; and
Water and Wastewater Transport within city borders
ICLEI’s CACP7 model is used to estimate emissions from residential, commercial, and
industrial consumption of energy and solid waste disposal. The California Air Resource
Board’s (CARB’s) EMFAC8 models were used to calculate transportation emissions, and other
sources were used for solid waste and wastewater sectors.
The majority of emissions are calculated using activity data and emissions factors. Activity
data refers to a measurement of energy use or another GHG-generation process, such as
residential electricity use, or vehicle miles traveled. Emissions factors are used to convert
activity data to emissions, and are usually expressed as emissions per unit of activity data (e.g.
metric tons carbon dioxide [CO2] per kilowatt hour of electricity). To estimate emissions, the
following basic equation is used:
[Activity Data] x [Emissions Factor] = Emissions
7 Clean Air and Climate Protection (CACP) is a model developed by ICLEI to inventory and forecast GHG emissions.
The 2011 update utilized the CACP 2009 Version 3.0 software.
8 The Emissions Factors (EMFAC) model was developed by CARB to measure various emissions from vehicles. There
are multiple versions of EMFAC which focus on different vehicle types.
July 14, 2020 Item #17 Page 18 of 128
As an example, multiplying the total amount of residential electricity use (activity data,
expressed in kilowatt-hours) by the emissions factor (expressed as CO2e emissions per
kilowatt-hour) produces the emissions in CO2e from residential energy use. The following
section describes the inputs for the community inventory based on activity data (or usage).
Table 2-1 below describes data sources for estimating activities and emissions factors.

Certain emissions that occur in the city are not counted in the community inventory. For
example, during the community workshop on the CAP some participants questioned why
emissions related to the Encina Power Plant are not included in Carlsbad’s GHG inventory.
The reason is as follows: embodied emissions, such as those resulting from power generation
that is produced locally but distributed regionally, are not covered in Carlsbad’s inventory, in
accordance with ICLEI standards. These emissions are included at the points where energy is
consumed (some of which are in Carlsbad) rather than where it is simply produced—otherwise
emissions would either be double counted, or if only counted at the production source,
electricity consumption (which is the second largest contributor to GHG) in climate action
planning would be meaningless. Similarly, for water consumed in Carlsbad, emissions
associated with its transport from Northern California and Colorado are counted in Carlsbad’s
inventory, rather than elsewhere.
The Carlsbad Desalination Plant, which will begin operations in 2016, would therefore not
contribute emissions to the 2011 GHG inventory. The emissions forecast (Chapter 3) uses a
regional average for water consumption emissions, which accounts for the effect of the
desalination plant. In general, including these large regional facilities would effectively add
GHGs from consumption of services outside of Carlsbad to the city’s emission totals.
The McClellan-Palomar airport is county owned and operated, and is outside of the city’s
jurisdiction. The city has little, if any, influence over airport operations, and emissions
associated with airport flight operations are excluded because they occur in a regional context.
For transportation trips that originate or end in Carlsbad, emissions for half of the entire trip
are included, and not just for the miles traveled within Carlsbad; however, trips that just pass
through Carlsbad are excluded, as their emissions would be reflected at their trip ends.9
Furthermore, although pass-through trips contribute a substantial amount to VMT totals, the
city and Carlsbad community has limited ability to influence them.
9 For example, for a trip that begins in downtown San Diego and ends in Carlsbad, the entire trip length is calculated for
that trip. Half of the entire trip length is assigned to Carlsbad, and the other half is assigned to the City of San Diego.
Using half the trip length is standard SANDAG methodology for assigning regional VMT to a particular city.

2.2 2012 Baseline Community GHG Inventory
Residential, Commercial, and Industrial (RCI) Electricity and
Natural Gas UsageGHG Emissions By Category
The inputs for the CACP model for the residential, commercial and industrial (RCI) sectors are
electricity and natural gas consumed. Table 2-1 shows RCI electricity and natural gas
consumption, and the total citywide consumption of electricity and natural gas. The
commercial sector has the largest electric consumption followed by residential and industrial.
The greatest natural gas consumption is from the residential sector, used for heating homes and
water, followed by commercial and industrial sectors. As discussed in Section 2.1, a GHG
inventory describes the emissions in various categories for a given calendar year. Some of the
inputs, such as electricity and natural gas, are based directly on consumption data. Others, such
as on-road transportation, are based upon model outputs. In order to determine a community’s
GHG emissions reduction targets, and its consistency with state reduction targets, a baseline
GHG inventory is needed. The City of Carlsbad is using the 2012 community GHG inventory
as its baseline for the purpose of deriving GHG reduction targets. A detailed description of the
community GHG inventory, including methods and inputs, is contained in Appendix B-1.

Differing emissions based on the source of electricity, either bundled or direct access
electricity, were taken into account. Bundled electricity is produced for SDG&E and
transmitted by SDG&E. Direct access electricity is produced elsewhere in the region but
ultimately transmitted to the consumer by SDG&E. Natural gas produces CO2e regardless of
source.
Transportation
Transportation emissions are based on vehicle miles traveled (VMT) for vehicles and off-road
equipment. GIS-based 2011 VMT data from SANDAG for all roadways was used. All
roadways including the zone connectors were used. The SANDAG data is reported as daily
weekday VMT. This was converted to annual VMT by multiplying it by 347, as recommended
by CARB.10 The total annual VMT in 2011 was 510,973,969 vehicle miles traveled.
CARB’s latest model, EMFAC2011, is made up of three modules: -SG, -LDV, and –HD. The
SG module covers all vehicle types, while LDV calculates light duty vehicles and HD
calculates heavy duty vehicles. Appendix B provides a more detailed explanation of how CO2e
were calculated using each module. As inputs, emissions from local roadway VMT and
freeway VMT were determined separately.
Off-road emissions in Carlsbad include lawn and garden equipment, construction equipment,
industrial equipment, and light commercial equipment. While CARB’s OFFROAD2007 model
generates emission outputs for 16 categories across San Diego County, only the off-road
emissions listed above are included, as they generate the most emissions in Carlsbad in this
category. The CO2, N2O, and CH4 emissions were calculated in short tons per day for the
county. These emissions were then pro-rated by the city’s share of the county population,
multiplied by 365 days, and converted to metric tons.
10 CARB recommends that 347 be used instead of 365 to convert from average daily VMT to annual VMT to account for
less travel on weekends.
July 14, 2020 Item #17 Page 22 of 128
Solid Waste
The default values in the CACP were used for solid waste emissions. For methane emissions
from the one landfill in the city limits—the closed Palomar Airport Landfill—the same data
from the 2005 community inventory was used, as it was unlikely to have changed substantially,
if at all.11
For emissions from solid waste disposed of in Carlsbad and taken to landfills elsewhere, 2011
data for Carlsbad was obtained from CalRecycle. The composition of waste was estimated
from the latest such survey, the 2008 CalRecycle Statewide Waste Characterization Study,
which has averages for the southern region of California. The amount of average daily cover,
which is made of plant debris, was also entered.
Wastewater Treatment
Emissions from methane and nitrous oxide generated in the process of wastewater treatment
were determined using the University of San Diego’s EPIC (Energy Policy Initiatives Center)
model. The EPIC estimate of GHG emissions from countywide wastewater treatment was used
and pro-rated to Carlsbad’s share of the county population.
Total Community Emissions
The total community GHG emissions were 705,744 MTCO2e in 2011. Table 2-2 summarizes
the sources and quantities of community emissions, and Figure 2-1 shows the emissions
graphically by sector. The largest sector is transportation, at 39 percent, followed by
commercial and industrial (32 percent), residential (25 percent), solid waste (3 percent) and
wastewater (1 percent).
11 In November 2014, city staff contacted the County of San Diego Public Works Department in response to a comment
on the draft CAP. County staff reported that for 2011, it calculated GHG emissions from Palomar landfill at 6,703
MTCO2e. Although it is unknown why the reported figure is higher than the assumed figure for the city’s GHG inventory update, County staff did note that their GHG calculation methodology had changed in 2010. The difference
in the County’s calculations of GHG emissions from Palomar landfill does not have a material effect on the
assumptions, conclusions, or recommendations of this CAP.

Table 2-6 shows the source of growth in emissions. The largest increase in emissions came
from commercial electricity usage (37% of increase), followed by residential electricity usage
(29%). All other emissions increased at a slower pace than the rate of population growth, with
emissions from residential natural gas consumption increasing by 9 percent, and all other
sources increasing by 5 percent, or decreasing, in the case of roadway emissions.
For electricity, the increase was largely caused by the increase (35%) in the CO2 generated by
SDG&E electricity since 2005. For example, residential electricity consumption increased by
10 percent but emissions from that source increased by 29 percent. Commercial electricity
consumption went up by 8 percent while related emissions increased by 37 percent—an even
higher increase as some commercial customers in the greater San Diego region switched from
cleaner direct access electricity to sources producing more CO2.

Table 2-7 shows the sources of emissions, ordered by volume of overall contribution. The
largest contributor continues to be transportation, but that has declined in proportion as
emissions from building energy consumption have grown faster. These sources—roadway
VMT, off-road vehicles, and private electricity and natural gas consumption—account for 96

2.3 Government Operations Inventory
Government operations represent a small portion (1.2%; see end of this section) of the
communitywide GHG emissions. However, more detailed information is available to
characterize GHG emissions by source and sector. The city has the ability to directly influence
emissions from government operations, and can provide community leadership in reducing
GHG emissions. As described before, the four sectors included in the government operations
inventory are buildings and facilities, vehicle fleet, public lighting, and water and wastewater
transport.
Buildings and Facilities
The inputs for this sector are electricity and natural gas. Data was entered by individual facility
along with departmental information. Table 2-8 lists all of the buildings and facilities operated

VEHICLE FLEET
The inputs for this sector are all vehicles used by the city. The key data used are fuel consumed
and VMT, broken out by model year, vehicle type, and fuel type. CACP uses fuel consumption
to calculate CO2 emissions and VMT to calculate NO2 and CH4 emissions.
Although the vehicle fleet data from the city was broken down by department, the inputs were
loaded into CACP as a single set for the entire city due to the time-consuming nature of
processing and entering this very detailed information.
Table 2-9 summarizes the inputs by vehicle and fuel type. Gasoline accounted for the largest
amount of fuel consumption (167,345 gallons) and greatest vehicle miles traveled (1,965,416
VMT).

mileage to account for the likely reality of most hybrid miles being under electric power during
low speed driving on local streets.
Public Lighting
This sector covers electricity consumed from three sources: traffic signals, streetlights, and
other outdoor lighting. As shown in Table 2-10, streetlights make up the great majority of
electricity consumption in this sector. Between 2005 and 2011, the city retrofitted its existing
streetlights with more energy-efficient lamps.

Greenhouse Gas Reduction
Target, Forecasts, and
Emissions “Gap”
This chapter describes the greenhouse gas (GHG) reduction targets provided by state law,
provides a baseline forecast of community GHG emissions, and models forecasts of future
community and local government GHG emissions through 2035. The chapter also quantifies
GHG reductions from (1) state and federal actions and (2) the updated Draft General Plan
policies and actions, and applies these reductions to the community forecast. The emissions
“gap” between the forecasts (with GHG reductions) and the emissions targets is addressed by
the Climate Action Plan (CAP) GHG reduction strategies in Chapter 4.
3.1 GHG Reduction Target
Governor’s Executive Order S-3-05 and the Global Warming
Solutions Act of 2006 Statewide GHG Reduction Targets and
2017 CARB Scoping Plan
Executive Order S-3-05 (EO S-3-05) and the California Global Warming Solutions Act of 2006
(AB 32 and SB 32) provide the basis for the CAP’s GHG emissions targets. EO S-3-
05Collectively they commits California to reduce its GHG emissions to 1990 levels by 2020,
to 40 percent below 1990 by 2030, and to 80 percent below 1990 levels by 2050. AB 32
codifies the 2020 target and tasks CARB with developing a plan to achieve this target.
CARB first approved the Scoping Plan in 2008, which provides guidance for local
communities to meet AB 32 and EO S-3-05 targets. The Scoping Plan recommended “a
greenhouse gas reduction goal for local governments of 15 percent below today’s levels by
2020 to ensure that their communitywide emissions match the state’s reduction targets.12 s that

FORECASTS, AND EMISSIONS “GAP”
local governments target 2020 emissions at 15 percent below 2005 levels to account for
emissions growth since 1990, as proxy for 1990 emissions, since few localities know those
levels. The 2014 First Update to Scoping Plan repeated that emissions reduction target and
provided guidance for local governments to develop post-2020 GHG reduction targets. It stated
that “there is a need for local government climate action planning to adopt mid-term and long-
term reduction targets that are consistent with…the statewide goal of reducing emissions 80
below 1990 levels by 2050.”13
CARB’s 2017 Climate Change Scoping Plan recommended statewide targets of “no more than
six metric tons CO2e per capita by 2030 and no more than two metric tons CO2e per capita by
2050.”14 These goals are based upon the 2030 and 2050 goals of 40 percent and 80 percent
reductions below 1990 levels and the projected population for those years. Using the statewide
GHG inventories, percentage reductions can be derived for various baseline years
Total Carlsbad GHG emissions from the 2005 2012 inventory were 630,310977,000 metric
tons carbon dioxide equivalents (MTCO2e) per year. Therefore, the 2020 target under State
guidance is a 415 percent reduction from 2005 2012 emissions, which corresponds to a target
of 535,763939,000 MTCO2e. The 2030 target would be 42 percent below 2012 levels and the
2050 goal would be 81 percent below 2012 levels.
The long range 2050 target set by EO S-3-05 is an 80 percent reduction from 2020 emissions
target, which represents the level scientists believe is necessary to stabilize the climate. The
2050 target for Carlsbad is citywide emissions of 107,153 MTCO2e. This is a substantial
decrease in overall emissions, over 500,000 MTCO2e below baseline 2005 emissions levels.
While CARB’s Scoping Plan does not specifically set target levels for intermediate years
between 20202030 and 2050, the Scoping Plan recommends a linear progression in annual
GHG emissions reductions to meet the final targets.
The horizon year for this CAP is 2035, corresponding with the Draft General Plan horizon. The
CAP uses a linear trajectory in emissions reductions between 2020 2030 and 2050 to determine
the 2035, target. Table 3-1 summarizes these emissions targets and the percentage reduction
from 2005 2012 emissions. Figure 3-1 graphs the emissions targets, following a linear
trajectory, from 2020 to 2035. As can be seen, the baseline exceeds the 2020 reduction target
by 15 percent, and the 2035 target by 49 percent.

3.2 Business as Usual Forecast
The first step in projecting GHG emissions is to calculate the business as usual forecast (BAU).
The business as usual (BAU) forecast estimates community emissions through the year 2035,
based on the growth in emissions from the 2005 to 2011 citywide inventoryin the absence of
any new policies or programs. The BAU calculation relies upon the latest data available, as
well as the most recent projections for population, housing and job growth. The increase in
community emissions from 2005 to 2011 was linearly projected outward to the year 2035. The
BAU forecast simply assumes that emissions will increase in the future at the same growth rate
that occurred between the 2005 and 2011 citywide inventories. Thus, BAU emissions are
forecast to reach 1,007,473 MTCO2e in the year 2035. The BAU calculation typically
represents a linear extrapolation of the most recent data, holding other variables constant.
The BAU includes emissions projections in the following categories:

The Statewide Energy Efficiency Collaborative model (SEEC) is used to predict community
GHG emissions across all sectors to 2035. A product of the collaborative, this tool is based on
the International Council for Environmental Initiatives’ (ICLEI’s) Clean Air and Climate
Protection (CACP) model used to estimate the 2005 and 2011 emissions inventories. The
primary reason for using SEEC rather than CACP is that SEEC includes the effects of the
Renewable Portfolio Standard (RPS) and Pavley I Fuel Economy Standards, whereas CACP
requires manual adjustment to account for the state-mandated electrical production and fuel
efficiency improvements. Section 3.4 quantifies other state and federal actions that reduce
GHG emissions and incorporates these actions into the forecast.
The SEEC community forecast predicts all direct GHG emissions15 from sources within the
boundaries of the City of Carlsbad, including fuel combusted in the community16 and direct
emissions from landfills within the community. Indirect emissions associated with the
consumption of energy that is generated outside the borders of the city are also included. Other
indirect or embodied emissions are not covered in the forecast, in accordance with ICLEI
standards. The SEEC community forecast tallies emissions from seven sectors:
Residential
Commercial
Industrial
Transportation
Solid Waste
15 GHGs considered in the report are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons.
The emissions have been converted to carbon dioxide equivalents (CO2e), which converts the three other GHGs into
the equivalent volume of carbon dioxide.
16 This does not include the Encina Power Station, for reasons described in Chapter 2.

Landfills17
Wastewater
The emissions projected in the SEEC community forecast use the activity data (or usage) from
the 2005 community inventory as an initial value, and the 2011 inventory to provide an
intermediate value to adjust the model. The predicted growth in each sector is then added into
the model to project future emissions. The following section describes how the predicted
growth in each section was determined.
Inputs
ResidentialOn-Road Transportation
Emissions related to on-road transportation are based upon the vehicle miles traveled (VMT)
and the average vehicle emission rate for the San Diego region. VMT is calculated using the
SANDAG Activity-Based Model and the Origin-Destination (O-D) method. 2035 VMT
projections are estimated from extrapolating SANDAG Series 14 2016 VMT data according
to service population. The service population is the sum of population and jobs, which is
projected to be 207,940 in 2035. With an average annual VMT of 1,231,554,425 miles, and an
average vehicle emission rate of 361 pounds of CO2e per mile, the projected 2020 emissions
from on-road transportation are 452,000 MTCO2e and 2035 emissions total 445,000 MTCO2e.
Electricity
Emissions projections from the residential electricity sector are from electricity and natural gas
demand. The growth in residential electricity and natural gas consumption was assumed to
scale with population growth, estimated at 0.9 percent per year thorough 2035, based on
General Plan buildout estimates. based upon the per capita electricity use on 2014 (2,159 kWh
per person per year) multiplied by the SANDAG Series 14 population forecast. The
commercial and industrial emissions projections are based upon per-job electricity
consumption on 2016 (6,936 kWh per commercial job per year and 10,126 kWh per industrial
job per year) multiplied by the SANDAG Series 13 job growth forecast. The projected 2020
emissions from electricity are 274,000 MTCO2e and 2035 emissions total 296,000 MTCO2e.
CommercialNatural Gas
The emissions projections for natural gas are calculated similar to those for electricity. Per
capita consumption for 2016 (118 therms per person per year, 151 therms per commercial job
per year, and 126 therms per industrial job per year) multiplied by population and job growth
forecasts. The projected 2020 emissions from natural gas are 137,000 MTCO2e and 2035 total
147,000 MTCO2e.
increase in commercial demand for electricity and natural gas was assumed to scale with the
General Plan employment forecasts to 2035 in the commercial sector by land use category:
17 The 2011 inventory considered landfill emissions as part of solid waste. The SEEC model separates out landfills from
solid waste as an emissions source, so the separation has been preserved in this chapter.

commercial, hotel, office, and other, including construction and transportation-related
employment. For 2010 to 2035, an annual growth of 1.1 percent was used.
IndustrialSolid Waste
The emissions from solid waste disposal are based upon the per capita disposed in 2016 (3.5
kilograms per person per day) multiplied by forecasted population growth. The projected 2020
emissions from solid waste are 36,000 MTCO2e and 2035 emissions total 37,000 MTCO2e.
growth rate in industrial electricity and natural gas demand was based on General Plan
employment forecasts to 2035 in the industrial sector. An annual growth rate of 0.8 percent
was used through 2035.
Off-Road Transportation—With General Plan Land Use and Circulation
System
The emissions from off-road transportation include four categories: lawn and garden
equipment, light commercial equipment, construction and mining, and industrial. Lawn and
garden equipment include sources such as lawn mowers, chainsaws and leaf blowers. Light
commercial equipment includes sources such as generators and pumps. The construction and
mining emissions sources include excavators, off highway tractors and paving equipment.
Industrial equipment sources include forklifts, aerial lifts and sweepers. These emissions are
derived from several models, such as OFFROAD2007 and RV2013, and the CARB In-Use
Off-Road Equipment 2011 Inventory. The projected 2020 emissions from off-road
transportation are 15,000 MTCO2e and 2035 emissions total 19,000 MTCO2e.
Transportation emissions are based on the emissions associated with VMT. The VMT
projections were taken from SANDAG GIS models of regional VMT projections clipped to
the city boundaries and adjusted to remove through trips, or trips that did not originate nor end
within city boundaries.18 The SANDAG data was reported as daily weekday VMT. This was
converted to annual VMT by multiplying it by 347, as recommended by CARB.19
The VMT forecasts incorporate GHG reductions from General Plan land use projections and
new roadway construction thorough 2035. These VMT forecasts reflect the General Plan land
use patterns, include the effects of compact and infill, mixed-use, and transit-oriented
development, and the protection of open space. New roadway construction includes the effects
of street extensions and citywide traffic signalization. The land use projections and new
roadway construction are described in detail in the General Plan.
The SEEC model automatically incorporates the effect of Pavley I Fuel Economy Standards.
Table 3-2 shows the citywide VMT for 2011 and projected VMT forecast, used to estimate
transportation emissions.

Solid Waste
Waste emissions from solid waste disposed of in Carlsbad and taken to landfills elsewhere,
was assumed to scale with population growth at 0.9 percent per year through 2035.
LandfillWater
The emissions from water are based upon the 2016 per capita water consumption (141 gallons
per person per day for potable water and 32 gallons per person per day for recycled water)
multiplied by forecasted population growth. The projected 2020 emissions from water are
9,000 MTCO2e and 2035 emissions total 9,000 MTCO2e.
Emissions from the landfill sector are an estimate of methane generation from the anaerobic
decomposition of all organic waste sent to a landfill. Within city boundaries, landfill emissions
are comprised of leaking methane from the closed Palomar Airport Landfill. Currently, most
of the methane generated at this capped landfill is captured. The EPA estimates 95 percent
methane capture rate for capped landfills and estimates that emissions follow a first-order
exponential decay. Therefore, baseline landfill emissions were estimated to decrease
exponentially over time, at a decay rate of 5 percent over 10 years to 2035, the largest allowed
percentage decrease in the model.
Wastewater
The emissions from wastewater are based upon the 2016 per capita wastewater generation (53
gallons per person per day) multiplied by forecasted population growth. The projected 2020
emissions from wastewater are 3,000 MTCO2e and 2035 emissions total 3,000 MTCO2e.
The Carlsbad Municipal Water District’s 2010 Urban Water Management Plan (UWMP) was
used to determine the growth in emissions from wastewater treatment.21 The demand for
20 VMT includes the effect of an additional 327 units above the growth cap in the Northwest Quadrant by 2035, as shown in the 2014 Draft General Plan. While the City Council will adjust housing sites or densities at adoption time so that
the development cap is not breached, the inclusion of these units in the CAP represents a conservative estimate that
leads to a slightly higher VMT (and corresponding GHG emissions) above levels anticipated under General Plan that
would be adopted.
21 Carlsbad Municipal Water District serves the majority of the city, with the exception of the southeast corner of the
City, which is served by Olivenhain Municipal Water District, and Vallecitos Water District. The changes in water
demand from the UWMP were assumed to be representative of the city as a whole for the purposes of the SEEC model.

wastewater treatment was assumed to scale with projected 2035 water deliveries listed in the
UWMP. The UWMP includes the effect of conservation policies. Table 3-3 shows water

Table 3-34 shows the emissions from the business-as-usualSEEC community forecast for each
sector—residential, commercial, industrial, transportation, solid waste, landfill, and
wastewater—and the sum total community emissions. The forecast includes the reduction from
RPS and Pavley I Fuel Economy Standards, which are quantified separately in Section 3.5,
below. The forecast also includes the effect of the General Plan land use and circulation system
on transportation emissions (compact, infill, mixed-use, and transit-oriented development,
open space protection, new traffic signals and roadway extensions). The Carlsbad General Plan
EIR quantifies the reduction in VMT due to the proposed General Plan in comparison to higher
VMT under the existing General Plan (the No Project alternative).
The greatest projected emissions continue to be from the on-road transportation sectorcategory,
which accounts for 48.91 percent of emissions in 2020 and 36 46.5 percent of emissions in
2035. Residential Electricity emissions are the next largest sectorcategory, with 29.66 percent
of emissions in 2020 and 28 just under 31 percent of the total in 2035. Commercial, industrial,
andEmissions from solid waste, off-road transportation, water and wastewater remain
relatively low compared to other categories., and landfill emissions are the next largest sectors
in order of total emissions.

The BAU projections of 926,000 MTCO2e for the Carlsbad community GHG emissions fall below
the 2020 target emissions level of 939,000 MTCO2e. Therefore, the next steps in the projections of
emissions only include a forecast for 2035.

Figure 3-4 shows the change in SEEC-modeled community forecast emissions over time. Total
emissions are projected to decrease from 705,744 MTCO2e in 2011 to 565,873 MTCO2e in
2020 (a decrease of 20 percent). The initial drop in emissions is mostly caused by the
implementation of the RPS, which causes a decrease in residential, commercial, and industrial
emissions, and Pavley I Fuel Economy Standards, which decrease transportation emissions.
Over time, the decreases in emissions from an increased amount of renewable power usage and
fuel efficiency improvements are canceled out by population growth, which cause emissions
to increase from 2020 values to 589,873 MTCO2e in 2035 (an increase of 4 percent).
In 2020, the total emissions of 565,873 are about 30,000 MTCO2e above the AB 32 target
emissions. The following section quantifies GHG reductions from State and Federal actions
and applies them to the emissions forecast.

3.43.3 Government Operations Forecast
Methodology
The SEEC government operations forecast, which is a subset of the community forecast, covers
direct emissions from the sources the City of Carlsbad owns and/or controls. The emissions
from government operations are included in the totals shown in Table 3-4 and Figure 3-4 above.
This section separates out emissions from government operations for accounting purposes. The
government operations forecast includes mobile combustion of fuel for city vehicles and the
use of natural gas to heat city buildings. Indirect emissions associated with the consumption of
electricity, steam, heating, or cooling for city operations that are purchased from an outside
utility are also forecast. All other indirect emissions sources, including employee commute and
the decomposition of government-generated solid waste, are not included as part of the local
government forecast, but rather are counted in the community forecast. The government
operations inventory covers emissions from the following sectors:

Wastewater Transport
The government operations forecast uses 2005 inventory to represent baseline emissions, and
the 2011 inventory to provide an intermediate value to adjust the model.
Within each sector, certain types of emissions are assumed to scale with population growth,
projected to grow at 0.9 percent annually through 2035, while other types of emissions are
expected to remain constant or decrease with efficiency improvements. The following sections
describe the assumptions underlying the forecast growth rates for each government operations
sector.
Buildings and Facilities
The 2005 and 2011 inventories of emissions from all buildings and facilities operated by the
city were used to determine the future growth for this sector. The natural gas and electricity
demands were assumed to scale with population for departments such as Police, Fire, and Parks
and Recreation, while others, such as Administration and Utilities, would remain staffed at
current levels. These growth rates were then combined to determine an aggregate annual
growth rate of 0.7 percent, which was applied to the buildings and facilities sector.
Vehicle Fleet
An estimate of the growth in the number of City employees was used to determine City fleet
use. The growth in fleet emissions beyond 2011 was estimated by assuming—similar to the
Buildings and Facilities sector—that certain departments would scale with population growth,
while others would remain staffed at current levels. These growth rates were then combined to
determine an aggregate annual growth rate of 0.6 percent, which was applied to the city fleet
sector.
Public Lighting
From 2005 to 2011, electricity use for streetlights decreased approximately 4 percent due to
the installation of some energy-saving induction streetlights. Following the completion of the
installation of all induction streetlights, the City’s electricity demand for streetlights was
further reduced, which is reflected in the forecast energy demands for this sector.
Water Delivery and Wastewater
The increased demand for energy usage for water delivery and wastewater was assumed to be
proportional to the amount of water delivered by the Carlsbad Municipal Water District
(CMWD), as projected in the 2010 Urban Water Management Plan (UWMP). CMWD’s
service area covers about 85 percent of the City, and it was assumed that water and wastewater
usage in the remaining 15 percent of the City, served by Olivenhain Municipal Water District

and Vallecitos Water District, would follow similar water use patterns as outlined in the 2010
UWMP.
Results
The city operations forecast for 2020 and 2035 is shown by sector in Table 3-5. Government
operations emissions are projected to decrease from the 2011 inventory total of 8,205 MTCO2e
to 5,185 MTCO2e in 2020. The decrease in emissions is primarily due to the implementation
of the RPS and the fuel efficiency gains from Pavley I standards. Emissions are forecast to then
increase at a low rate through the year 2035 to 5,922 MTCO2e, due to projected increases in
city staff in select departments to accommodate an increased need for city services.
The relative contribution of each sector to the total city operations emissions is generally
constant over time. The two largest emissions sectors are buildings and facilities, comprising
about 40 percent of total emissions, and fleet emissions, which are approximately 33 percent
of the total emissions. Streetlights are about 15 percent of total emissions, followed by
wastewater facilities at 8 percent, and water delivery facilities at 1 percent. Overall,
government operations emissions are forecast to remain a small portion of community
emissions, about 0.9 percent in 2020 and 1 percent in 2035. Chapter 4 discusses mitigation
measures that will reduce government operations emissions.

3.53.4 GHG Reductions to Community Forecast from
State and Federal and State Actions
Methodology
The next step in projecting GHG emissions is the consideration of GHG reductions from state
and federal actions and other trends to the community forecast are quantified in this section.
This projection is known as the legislatively-adjusted BAU since it still lacks any potential
GHG reductions from local policies and programs.
July 14, 2020 Item #17 Page 48 of 128
CARLSBAD CLIMATE ACTION PLAN

The federal and state actions included in the legislatively-adjusted BAUThese reductions
include the following:
Renewable Portfolio StandardFederal and California Vehicle Efficiency Standards
Pavley I fuel economy standardsCalifornia Energy Efficiency Standards
Low Carbon Fuel StandardCalifornia Solar Policy, Programs and 2019 Mandates
Title 24 building efficiency improvementsRenewable Portfolio Standard
Reductions in VMT from rising gasoline prices22
The GHG reductions from these factors were quantified using the EPIC mitigation calculator.
The Energy Policy Initiatives Center (EPIC) at the University of San Diego developed this
model to create business-as-usual projections, set targets, and calculate levels of mitigation
measures for all local jurisdictions in the San Diego region. As the EPIC model was developed
specifically for cities within San Diego County and the mitigation calculator calculates the
effect of the federal and statewide reductions, it was selected to quantify these policies and
actions. GHG reductions from the RPS and Pavley I fuel economy standards were accounted
for in the SEEC model; however, they are quantified separately in this section for informational
purposes.
Renewable Portfolio Standard (RPS)Federal and California Vehicle
Efficiency Standards
California’s RPS, established in 2002 by the California State Senate in Senate Bill 1078,
accelerated in 2006 and expanded in 2011, is one of the most ambitious renewable energy
standards in the country. The RPS requires that investor-owned utilities like SDG&E supply
33 percent of their electricity from renewable resources by 2020. While a renewable portfolio
standard past 2020 has not been established, the assumption used in the EPIC mitigation
calculator was that the 33 percent renewable standard would be extended through the year
2035—a conservative assumption, given that this is targeted to already be attained by 2020. .
Table 3-6 lists the reductions from the RPS in 2020 and 2035.
The federal and California vehicle efficiency standards vary by type of vehicle. For passenger
cars and light-duty vehicles, the applicable standards are the Federal Corporate Average Fuel
Economy (CAFE) standards and California Advanced Clean Car (ACC) Program. The CAFE
standards are developed by the U.S Department of Transportation’s National Highway
Transportation Safety Administration (NHTSA) and regulate how far vehicles must travel on
22 The rise in gasoline prices are not a result of any state or federal policy or action, but are included in this section as
part of a larger systemic trend forecast to occur regardless of other emission reduction measures.

a gallon of fuel. The ACC program was adopted by CARB and combined the control of smog-
causing pollutants and GHG emissions into a single coordinated package of regulations.
For heavy-duty vehicles (heavy-duty trucks, tractors, and buses), the applicable regulations are
the U.S. Environmental Protection Agency’s (US EPA) Phase-I GHG Regulation and CARB
Tractor-Trailer GHG Regulation. The US EPA regulation was developed in coordination with
the NHTSA and calls for GHG emissions and fuel economy standards. The CARB regulation
reduces GHG emissions by improving aerodynamic performance and reducing the rolling
resistance of tractor-trailers. The reductions projected from the federal and California vehicle
efficiency standards total 113,968 MTCO2e in 2035.

Pavley I Fuel Economy StandardsCalifornia Energy Efficiency Programs
In 2009, CARB adopted amendments to the Pavley regulations to reduce GHG emissions in
new passenger vehicles from 2009 to 2016. The standards set became the model for the updated
Corporate Average Fuel Economy (CAFE) standards set by the US EPA. The emissions
reductions from the improved fuel efficiency standards were calculated using the EPIC
mitigation calculator, and were phased in following the 2011 inventory. Table 3-7 lists the
emissions reductions from Pavley I fuel economy standards in 2020 and 2035. These
reductions are already quantified and applied in the SEEC community forecast, and have been
listed separately here for reference purposes. In September 2017, the California Public
Utilities Commission (CPUC) adopted energy efficiency goals for ratepayer-funded energy
efficiency programs (Decision 17-09-025); these went into effect in 2018. The sources of the
energy savings include, but are not limited to, rebated technologies, building retrofits,
behavior-based initiatives, and codes and standards. The reductions projected from the
California energy efficiency programs total 19,110 MTCO2e in 2035.

Low Carbon Fuel StandardCalifornia Solar Policy, Programs and 2019
Mandates
The Low Carbon Fuel Standard, adopted by CARB, is performance-based and is designed to
reduce the GHG intensity of transportation fuels by 10 percent by 2020. The regulation
established annual performance standards that fuel producers and importers must meet
beginning in 2011. The Low Carbon Fuel Standard applies to all fuels used for transportation
in California, including gasoline, diesel fuel, E85, compressed or liquefied natural gas, biogas,
and electricity. The Standard is also “lifecycle” based, meaning the entire extraction, recovery,
production and transportation of the fuel is taken into account. The default assumption of 10
percent reduction in GHG intensity was assumed to continue through 2035 for the EPIC
mitigation calculator. Table 3-8 shows the reductions from the Low Carbon Fuel Standard in
2020 and 2035. California has several policies and programs to encourage customer-owned,
behind-the-meter PV systems, including the California Solar Initiatives, New Solar Home
Partnership, Net Energy Metering, and electricity rate structures designed for solar customers.
The California Solar Initiative is the solar rebate program for customers of the investor-owned
utilities, including SDG&E. The New Solar Home Partnership provides financial incentives
and other support to home builders to encourage the construction of new, energy efficient solar
homes. This assistance terminates on December 31, 2021. Net Energy Metering provides utility
customers a credit for the unused electricity produced by their solar system. The new California
2019 Building Energy Efficiency Standards, which went into effect on January 1, 2020, require
all newly constructed single-family homes, low-rise multi-family homes, and detached
accessory dwelling units (ADUs) to have PV systems installed, unless the building receives an
exception. The reductions projected from the California solar policy, programs and 2019
mandates total 37,125 MTCO2e in 2035.

Title 24 Building Efficiency ImprovementsRenewable Portfolio Standard
Title 24 is California’s Building Energy Code, which is updated every three years. In 2010,
Title 24 was updated to include the California Green Building Standards Code, referred to as
CALGreen. CALGreen requires that new buildings reduce water consumption, increase system
efficiencies, divert construction waste from landfills, and install low pollutant-emitting finish
materials. CALGreen has mandatory measures that apply to nonresidential and residential
construction. The most recent CALGreen code became effective in 2014.

3-18
The Title 24 building efficiency improvements determine the effect of the CALGreen code
mandatory measures for new building construction using the 2010 code update.23 Table 3-9
lists the GHG reductions from building efficiency improvements in new construction
calculated using the EPIC mitigation calculator in 2020 and 2035. SB 100, the 100 Percent
Clean Energy Act of 2018, adopts a 60% RPS for all of California’s retail electricity suppliers
by 2030; this increased the RPS standard from 50% to 60%. The legislation also provides goals
for the intervening years before 2030 and establishes a State policy requiring that “zero-
carbon” resources supply 100% of all retail electricity sales to end-user customers and all State
agencies by December 31, 2045. If interpolated linearly between 60% renewable in 2030 and
100% zero-carbon in 2045, the interim 2035 target would be 73% renewable. The reductions
projected from the RPS total 186,115 MTCO2e in 2035.

Reduction in VMT from Rising Gasoline Prices
The U.S. Energy Information Administration (EIA) collects, analyzes and disseminates
independent and impartial energy information, including projections of future gasoline prices.
The 2013 EIA gasoline projection estimate a pump price of gasoline of $4.00 per gallon in
2020 and $6.00 in 2035 per gallon in California.24
The EPIC mitigation calculator measures emissions reductions from changes in fuel
consumption as a result of gasoline price increases. The reductions in GHG emissions based
on the Energy Information Administration gasoline prices are shown in Table 3-10. Although
the projected rise in gasoline prices is not the direct result of a federal or state policy, this effect
was considered in this section, as it is a larger systemic trend that is forecast to occur regardless
of other emissions reductions measures.

3.63.5 Modified Baseline: GHG Reductions from
Additional General Plan Policies and Actions
Methodology
This section describes General Plan policies and actions that reduce GHG emissions, quantifies
emissions reductions, and explains how these policies and actions will be implemented. These
reductions are from policies and actions in addition to Pavley I, the RPS, and the General Plan
land use and circulation system, which incorporate reductions from “No Project” conditions
which are already reflected in the SANDAG modeling discussed previouslyBAU and
legislatively-adjusted BAU discussed in previous sections. The General Plan policies and
actions are organized according to the following categories:
Bikeway System Improvements
Pedestrian Improvements and Increased Connectivity
Traffic Calming
Parking Facilities and Policies
Transportation Improvements
The California Air Pollution Control Officers Association’s (CAPCOA’s) Quantifying
Greenhouse Gas Mitigation Measures report was developed as a resource for local
governments to assess emissions reductions from GHG mitigation measures. This section uses
the methodology outlined in the CAPCOA report for each category to quantify emissions
reductions from the General Plan policies and actions.25 The reductions are applied to the
community forecast in the following section to get the “modified baseline” forecast.

Policy/Action Description
The Carlsbad Bikeway Master Plan, referenced in the General Plan, recommends the
enhancement of the existing bicycle network with the implementation of new Class I bike
paths, new Class II bike lanes, and new Class III bike routes, resulting in a 111.5 mile bikeway
system. The planned bikeways include the Coastal Rail Trail, a Class I bike path on Carlsbad
25 While many of the policies and actions quantified in the report are project-level in nature, much of the supporting
literature is from studies on a citywide, countywide, or regional context. The methodology in this section is based on
these regional studies, which is therefore applicable to the General Plan policies and actions listed in this section.

Boulevard at Ponto, two Class II bike lanes – one on Hillside Drive and another on Avenida
Encinas, and five Class III bike route projects in the northwest quadrant of the city.
In addition to Bikeway Master Plan recommendations, the Mobility Element identifies the
following new connections to improve connectivity in the area:
A new Class I trail at the terminus of Cannon Road and extending eastward toward the
City of Oceanside
A new Class I trail along the Marron Road alignment between El Camino Real and the
City of Oceanside
A new crossing of the railroad tracks at Chestnut Avenue.
Also, CalTrans’ North Coast Corridor Public Works Plan includes, among other
improvements, a new North Coast Bike Trail and new bicycle/pedestrian connections across
Batiquitos and Agua Hedionda Lagoons.
Finally, the city can install new and enhanced bicycle facilities as opportunities arise in
conjunction with street maintenance and rehabilitation, and as part of “road diet” projects.
Quantification
An estimated 0.05 percent reduction in transportation GHG emissions is assumed to occur for
every two miles of bike lane per square mile in areas with density greater than 2,000 people
per square mile.26 Carlsbad currently has approximately 2,700 people per square mile, greater
than the threshold of 2,000 people per square mile.
With the 111.5 miles of bicycle facilities, there would be approximately 2.85 miles of bikeways
per square mile, which corresponds to a 0.07 percent reduction in VMT emissions, or about
164 MTCO2e in 2020, and 147 608 MTCO2e in 2035.27
Implementation
The bikeway system enhancements will occur incrementally (at approximately .6 miles/ year)
through the implementation of the General Plan and planned and opportunistic bikeway
improvements (e.g., in conjunction with street maintenance and rehabilitation, or as part of a
“road diet”). Improvements will be funded and/or installed as conditions on new private
development as well as through the city’s multi-year CIP and annual operating budget process.
Funding sources may include development impact fees, general funds, local, state, and federal
grants.

Policy/Action Description
Pedestrian Improvements
Carlsbad has adopted several programs and plans related to improving the walking
environment. The city’s Pedestrian Master Plan guides the future development and
enhancement of pedestrian facilities to ensure that walking becomes an integral mode of
transportation in Carlsbad. The Carlsbad Residential Traffic Management Program provides a
mechanism for community members to report issues relating to speeding and traffic volumes
on residential roadways, assisting the city in “calming” traffic in these areas to make them
more comfortable for pedestrian travel.
Physical barriers to pedestrian access include gaps in sidewalks, high-volume, high-speed
streets, a circuitous roadway system in several parts of the city, and regional infrastructure such
as freeways and railways that presents barriers to pedestrian mobility. There are four significant
concentrations of high pedestrian improvement needs across the City of Carlsbad, including
the following locations:
The entire northwest quadrant, especially the Carlsbad Village area
The southern coastal area along Carlsbad Boulevard, between Cannon Road and La
Costa Avenue
Several locations along El Camino Real, near Camino Vida Roble, Aviara Parkway/Alga
Road and La Costa Avenue
The southeastern portion of the city, stemming from the intersection of La Costa Avenue
and Rancho Santa Fe Road
A range of potential improvement projects exists throughout the city, as identified in the
pedestrian master plan, to enhance pedestrian mobility, local connectivity, usage, safety and
accessibility. These improvements include filling in gaps in sidewalk connectivity, upgrading
substandard sidewalks, creating new connections to pedestrian attracting designations (such as
access across the railroad track to the beach at Chestnut Avenue, for example), establishing
safe routes to school, enhancing crosswalks, installing pedestrian countdown signals,
improving signage, and providing ADA improvements.

3-24
Increased Connectivity
Increasing connectivity in the city is critical to achieving the Carlsbad Community Vision.
There are a number of improvements described in the General Plan that will enhance
connectivity for bicycles and pedestrians, as noted below:
Cannon Road east of College Boulevard – Provide a bicycle/pedestrian facility that
would begin at the current eastern terminus of Cannon Road and continue eastward to
the city’s eastern boundary.
Marron Road Connection – Provide a bicycle/pedestrian facility that would begin at the
current eastern terminus of Marron Road and extend eastward to the city’s eastern
boundary.
Additional crossings of Interstate-5 and the railroad – Continue to look for opportunities
to add crossings of these two barriers and improve east-west connectivity to and from the
coast. Key connections will include a crossing at Chestnut Avenue (bicycle, pedestrian,
and vehicular) under the freeway and (bicycle and pedestrian) across the railroad, and a
Chinquapin Avenue connection (bicycle, pedestrian, and vehicular) over the freeway and
(bicycle and pedestrian) across the railroad. Additionally, Caltrans is designing a number
of new pedestrian and bicyclist connections along and across Interstate-5 and near the
lagoons as part of the Interstate-5 North Coast Corridor Public Works Plan. The city will
continue to coordinate with Caltrans on these improvements.
Improved accessibility to the lagoons and to the coast are envisioned to improve
connectivity to those areas.
Quantification
Providing an improved pedestrian network and increasing connectivity encourages people to
walk more and results in people driving less, causing a reduction in VMT. An estimate of a 1
percent reduction in VMT from pedestrian improvements and connectivity was assumed,
which corresponds to a reduction of 2,341 MTCO2e in 2020 and 2,106615 MTCO2e in 2035.28
Implementation
Pedestrian improvements and increased connectivity will occur through implementation of the
Pedestrian Master Plan, the Residential Traffic Management Program, and the General Plan,
and through planned and opportunistic pedestrian improvements (e.g., in conjunction with
street maintenance and rehabilitation, or as part of a “road diet”). Improvements will be funded
and/or installed as conditions on new private development as well as through the city’s multi-
year CIP and annual operating budget process. Funding sources may include development
impact fees, general funds, local, state, and federal grants.

Policy/Action Description
The Carlsbad Residential Traffic Management Program provides a mechanism for community
members to report issues relating to speeding and traffic volumes on residential roadways,
assisting the City in “calming” traffic in these areas to make them more safe and comfortable
for pedestrian travel. Traffic calming devices include speed tables, speed bumps, roundabouts,
and other devices that encourage people to drive more slowly or to walk or bike instead of
using a vehicle, especially for short trips in and around residential neighborhoods. The
residential traffic management program is implemented by the Transportation Division and
funded through the annual budget appropriation process.
Quantification
CAPCOA’s “Quantifying Greenhouse Mitigation Measures” was used to quantify the effect of
traffic calming devices. A 0.25 percent reduction in VMT was assumed to occur from these
improvements, which corresponds to a reduction of 585 MTCO2e in 2020 and 526 969
MTCO2e in 2035.
Implementation
The traffic calming improvements will occur through the implementation of the Residential
Traffic Management Program and the General Plan.

Policy/Action Description
Getting parking right is critical to ensuring the success of any urban area. Inadequate parking
is inconvenient and frustrating for businesses and residents. Too much parking underutilizes
valuable land, results in lower density development, discourages use of other forms of
transportation (such as public transit), spreads out land uses, and creates gaps in store fronts;
thereby practically requiring the use of the automobile. Additionally, too much parking also
requires more driveways for accessibility, introducing conflicts between pedestrians and
vehicles. Overly high parking requirements—particularly in downtown areas or urban cores—
can impact the ability to renovate or repurpose older buildings and revitalize activity centers
that can be better served and connected by enhancing facilities and amenities for bicyclists and
pedestrians. Therefore, it is important to “right size” and manage parking such that there is

enough to support the needs generated by the use, but not so much that it wastes land and
impairs other ways of getting around.
The city’s Zoning Ordinance provides standards for parking facilities based on development
types within the city. To promote “right sizing” of parking facilities, the following techniques
are included as part of the General Plan Mobility Element:
Shared Parking – continue to allow uses that have different parking demands at different
times of the day to share the same parking facilities. This is an effective way to minimize
pavement, allow denser land use, provide for more landscaping, and provide improved
walkability within a mixed use area. The best example of shared parking is an office
building and an apartment building as office’s peak parking demand occurs at 10:00 a.m.
and apartment’s peak parking demand occurs at 11:00 p.m.
Collective Parking – allow uses in mixed use projects/areas to utilize up to 50 percent of
project site’s vacant on-street parking to count toward their parking supply requirements.
Unbundled Parking – rather than provide free guaranteed parking, “unbundle” the
parking from the development and require residents and/or employees to pay for use of
a parking space.
Park Once – a strategy in destination districts to enable visitors to “park once” and visit
a series of destinations. Park once strategies work well in areas like the Village and areas
that are well connected by pedestrian and bicycle facilities. The creation of centralized
parking areas supports this strategy.
In Lieu Parking Fees – continue strategies in appropriate areas by which developers can
contribute fees toward the development of a common parking facility in lieu of providing
on-site parking. This works best in downtown or concentrated commercial areas, works
well to assist in paying for unified structured parking, and provides developers an
opportunity to increase density on their parcels.
Parking Management Strategies –a business district or businesses manage high demand
parking locations and destinations through a number of different strategies including
demand pricing, time restrictions, valet parking, and other techniques.
Public-Private Partnerships –the city, business owners, and developers collaborate to
provide both private and public parking opportunities. Instances where this works well
include parcels owned by the city, where a private entity comes in and develops,
manages, and enforces the parking in these public lots.
Parking Locater Signs – electronic monitoring devices that identify the available parking
in a given facility and utilize changeable message signs to assist travelers in identifying
available parking locations. Please note that this may require modifications to the city’s
zoning ordinance to be implemented in some areas of the city.
Parking Wayfinding Signs – signs identifying where public parking is available, which
support the “park once” concept.
July 14, 2020 Item #17 Page 60 of 128
CARLSBAD CLIMATE ACTION PLAN
3-27
Reduced Parking Standards – reduce parking standards in areas that are well served by
transit, provide shuttle accessibility to the COASTER station, provide parking cash out
programs (where employers pay employees to not park on site), or provide other
programs that will reduce parking demand.
Biking Equals Business Program – businesses provide bicycle parking or corrals and
provide incentives to encourage their patrons and employees to ride rather than drive.
Transit Equals Business Program – businesses provide their customers and employees
incentives to encourage them to use transit rather than drive.
Bicycle Corrals in Lieu of Vehicle Parking – for certain businesses, reduce required
onsite parking for vehicles if they provide a bicycle corral that accommodates more
people.
Although there are additional parking strategies that are available and may become available
in the future, most of the strategies work best in smart growth/mixed use development areas
and will be necessary to accomplish the goals and visions identified in the General Plan and
the General Plan Mobility Element.
Quantification
According to CAPCOA’s Quantifying GHG Mitigation Measures, parking strategies have
estimated VMT reductions. Reduced parking standards and other policies reducing parking
availability have an estimated 5 to 12.5 percent VMT reduction, unbundled parking cost has a
2.6 to 13 percent VMT reduction, and parking management strategies have a 2.8 to 5.5 percent
VMT projection.29 Conservatively assuming the combined effect of these parking reduction
strategies would result in the lower end of the strategies results, and considering that the
strategies would be most applicable in future growth and infill areas, the cumulative reduction
from implementations would result in a 2 percent VMT reduction to give an estimated 4,682
MTCO2e reduction by 2020, and a 4,2116,618 MTCO2e reduction by 2035.
Implementation
The parking strategies will occur through the implementation of the Zoning Ordinance and the
General Plan. The city’s Planning Division is primarily responsible for developing new
ordinances and updating existing ones. Parking policy and ordinance changes would be carried
out under the Planning division’s annual budget authority.

Policy/Action Description
Transit in Carlsbad includes bus service, ADA paratransit service, and the COASTER
commuter rail; indirectly, transit service is also provided by the Sprinter light rail system,
Amtrak rail service, and Metrolink commuter rail. Future transit service in the city will
primarily be coordinated by the North County Transit District (NCTD). In addition, there are
several planned transit improvements for Carlsbad that are part of San Diego Association of
Governments (SANDAG) regional planning efforts. These are reflected in the General Plan
Mobility Element:
Coastal rail improvements are proposed for the tracks serving the COASTER and
Surfliner trains in San Diego County along the Los Angeles to San Diego Rail Corridor.
These proposed improvements include double tracking, bridge replacements, and station
improvements. Improvements to the COASTER service (2020 and 2030) are also
proposed and would increase service and reduce headways.
Route 471 (2020) is a proposed rapid bus providing frequent service between Carlsbad
and San Marcos via Palomar Airport Road. This route will operate with 10 minute
headways during peak and off-peak hours. In the city, this rapid bus route is envisioned
to be supported by signal priority at intersections.
AMTRAK will add service to Carlsbad.
As previously described, the above future transit improvements will continue to advance
the backbone transit infrastructure. However, one key component to improving transit
use is improving the “first mile/last mile” access and experience for transit users. This
typically includes end of trip facilities (bike racks, showers, changing rooms, etc.) and
better connectivity from the transit stop to the ultimate destination via bicycle facilities,
pedestrian facilities, local transit circulators, etc.
Carlsbad’s future transit effectiveness will depend on major employers assisting with
providing some of these “first mile/last mile” facilities through transportation demand
management (TDM) measures. TDM is envisioned to include shuttle circulators to
major employers and destinations, showers and changing rooms at those locations, and
a host of other typical TDM techniques that would support transit usage and the
connection to the ultimate destination. This Mobility Element also supports TDM
through potential incentives (such as reduced parking standards for TDM
implementation) to further support transit access to these destinations.
The final component to improving transit use in the city is working with NCTD to
improve the transit experience, particularly along the bus routes. This includes
improving bus stops in the city to ensure that they are well lit, have seating, and are
covered to protect users from inclement weather.
As part of the FY 2014-2015 capital improvement program, the city initiated work on a Coastal
Mobility Readiness Plan. This plan will complement current and planned bicycle and
pedestrian improvements by recommending policy and infrastructure investments that will:
improve accessibility to transit and para-transit services; fill in transportation gaps (“first mile-
last mile” solutions); support and encourage expanded use of low-emission and zero emission
vehicles; provide viable alternatives to private, single-occupant vehicle use (such as through
July 14, 2020 Item #17 Page 62 of 128

3-29
car-sharing, bike-sharing, and local shuttles); and recommend other transportation/parking
demand management strategies. The plan will emphasize efficiently connecting residents and
visitors among the city’s various coastal activity centers, beaches, the state campground, and
to and from major hotels and resorts, the Village, major shopping centers, and other significant
visitor-serving activity centers. The plan will identify effective, proven tools, and seek out
promising and emerging technologies. The plan will also identify potential funding partners
such as NCTD (e.g. Cooperative Agreements in accordance with NCTD Board Policy 22),
private funding and/or public grants. The plan is expected to be completed at the end of 2015,
with implementation beginning in 2016.
The city has also implemented a state-of-the-practice traffic signal management (TSM) system.
This system integrates traffic signals in the city to a single access point, allowing city staff to
monitor and update signal timings to improve safety and mobility for all users in the city. The
Mobility Element supports further implementation of this program and use of other
technologies that become available, which have the ability to improve mobility for all users of
the city’s transportation system.
Quantification
Transportation system improvements can result in VMT reductions. According to CAPCOA’s
Quantifying Greenhouse Gas Mitigation Measures, transit system improvements can result in
the following reductions: 0.02 to 3.2 percent VMT reduction from a bus rapid transit system,
0.1 to 8.2 percent VMT reduction from expanding the transit network, 0.02 to 2.5 percent VMT
reduction from increasing transit service frequency and speed, and 0.5 to 24.6 percent VMT
reduction from increasing transit accessibility. Reductions from TSM were estimated using
Cambridge Systematics’ Moving Cooler report as a 0.01 percent VMT reduction.
Conservatively assuming the combined effect of these strategies, summing the low end of the
VMT reduction ranges gives a 0.63 percent reduction in VMT emissions.
Implementation
Transit improvements will primarily be coordinated by NCTD and will also be implemented
by SANDAG regional planning and funding efforts. City-led improvements will be carried out
through the city’s multi-year CIP and annual operating budget appropriation process.
Results
Table 3-12 shows the GHG reductions from each of the above General Plan policies and
actions. The largest reduction comes from parking facilities and policies, followed by
transportation improvements, traffic calming, pedestrian improvement and increased
connectivity, transportation improvements, traffic calming, and bikeway system
improvements. VMT emissions are projected to fall in the future due to higher fuel efficiency
standards; however, as the efficiency gains are expected to be largely achieved by 2020 but the
VMT is projected to continue climbing in the future, the effect of the VMT reductions are
greater in 2020 than in 2035 for all General Plan policies and actions considered in this section.
For example, the reductions from traffic calming in 2035 are 526 MTCO2e, which is less than
the reduction in 2020 of 585 MTCO2e. The reductions from these policies and actions are
incorporated into the community emissions forecast in the following section.

Table 3-13 shows the total community emissions with the reductions from the following
policies and actions:

Federal and State and federal actions
Additional General Plan policies and actions
Figure 3-6 shows the “modified baseline forecast,” which incorporates the reductions discussed
thus far in comparison to the emissions targets. Emissions drop steeply to 2020 from the
combined effect of GHG reduction policies and actions, continue a gradual decline to 2030,
but then start rising again after that, given that no increases in federal or state standards relating
to fuel efficiency or renewable energy are assumed, even though these may well occur by that
time. The BAU forecast for 2020 already meets the target reduction of four percent below
baseline; therefore, no analysis of the effects of federal and state policies and additional
General Plan policies was necessary. With the effect of all the GHG reductions considered in
this chapter, the total community forecast emissions are 473,082 MTCO2e in 2020, and
455,556 MTCO2e in 2035. Table 3-13 shows that Carlsbad will meetmet its target for 2020
without any additional measures. However, by 2035, there is a GHG emissions “gap” of
134,098116,817 MTCO2e —approximately one-third20 percent of the total projected
community emissions.

CAP GHG Reduction
Measures
The forecast emissions in Chapter 3 incorporate reductions from (1) state and federal actions,
(2) General Plan land use and roadways, and (3) additional General Plan policies and actions.
This chapter describes additional GHG reduction measures to close the emissions “gap”
between emissions targets and forecast emissions for 2035. These are:
Residential, Ccommercial and industrial photovoltaic systems
Building cogeneration
Single-family, multi-family and commercial efficiency retrofits
Commercial commissioning
CALGreen building code
Solar water heater/heat pump installation
Efficient lighting standards
Increased zero-emissions vehicle travel
Transportation Demand Management (TDM)
Citywide renewable projects
Water delivery and conservation
The sections below describe the GHG reduction measures and explain how they will be
implemented. The GHG reductions from these measures were quantified using the Energy
Policy Initiatives Center (EPIC) mitigation calculator, a tool developed by the University of
San Diego for cities within San Diego County. The EPIC mitigation calculator includes a
“business as usual” (BAU) forecast for each measure estimating GHG reductions from trends
already underway that will occur without any additional city intervention, based on regional
San Diego Gas & Electric (SDG&E) forecasts. For example, under the BAU forecast for
residential photovoltaic (PV) systems, the EPIC mitigation calculator estimates that by the year
2035, energy produced by residential PV systems in the City of Carlsbad will be about 15.9
megawatts (MW), which will offset about 6,233 metric tons CO2e (MTCO2 e).

4: CAP GHG REDUCTION MEASURES
4-2
The GHG reduction measures describe goals, amount of reduction in 2035, and actions to meet
the target levels. The actions are categorized as short-term actions that will be implemented
within one to two years of CAP adoption; or mid-term actions that will be implemented within
two to five years of CAP adoption. Actions identified as short to long-term, or mid to long-
term are those actions that will begin in the short or mid-term, but take longer than five years
to fully implement. Ongoing actions are those that continue throughout the duration of CAP
implementation. The mixture of short-term, mid-term, and long-term, and ongoing actions
presented for each measure are intended to meet the goals in a realistic timeframe and provide
an effective combination to reach the targets set forth. The “already-projected” amount is based
on the forecast BAU emissions reduction, followed by a target level to reach the goal of the
measure. The measures are then described in greater detail, as is the method of quantifying the
GHG emissions reduction, and the responsibility and implementation of the measure is
discussed. Each measure qualitatively describes costs and benefits, both to the city and the
private sector. Overall benefits of GHG emissions reductions include decreased costs through
energy efficiency, reduced risk to human health and welfare, and less global climate change.
The GHG reduction mitigation measures identified in this chapter are expected to achieve the
targeted emission reductions. However, the nature, location, timing, size and other
characteristics of future development projects may vary widely and additional project-level
mitigation measures may be helpful or necessary to assist individual projects to achieve the
targeted reductions. Accordingly, Appendix E to this Climate Action Plan provides a non-
exclusive list of mitigation measures to be considered by the City and project applicants during
project-level environmental review and adopted as needed to ensure that individual
development projects achieve the targeted emission reductions.
Note: CAP Amendment No. 1, approved May 5, 2020, recalculated the anticipated 2035 GHG
reductions for all measures, based upon new state and federal policies and the interaction
between the existing measures and new Measure P – Community Choice Energy. Four
measures, Measures A, C, G and H, were eliminated for reasons described below. CAP
Amendment No. 1 also updated the Actions calling for ordinance adoption; however, no other
Actions were updated with this amendment. This update will occur with the comprehensive
CAP update being processed in 2020-21.
4.1 Residential, Commercial and Industrial Photovoltaic
Systems
Measure A: Promote Installation of Residential Photovoltaic Systems – Deleted in CAP
Amendment No. 1
Goal: Promote installation of residential PV systems to produce
an additional 9.1 MW above already projected amounts, or the
equivalent of 2,682 more homes with PV systems, by 2035.
2035 Reduction: 10,136 MTCO2eN/A
This Measure is no longer needed due to Section 150.1(c)14 of the 2019 California Energy Code,
mandating all new low-rise residential construction include solar photovoltaic energy generation systems.
Actions:
A-1: Temporarily—for a period of one year—suspend residential and commercial PV system permit
fees, together with a publicity campaign to promote PV systems installation (Short-term)
July 14, 2020 Item #17 Page 67 of 128
CARLSBAD CLIMATE ACTION PLAN
4-3
A-2: On a continuing basis, ensure that regulatory provisions - such as complying with regulations for
zoning, structure height, permit submittal and review, etc. - do not hinder residential and
commercial PV system installation. (Short to Long-term)
A-3: Adopt an ordinance, similar to those passed by Lancaster and Sebastopol, which requires new
homes to install PV panels to offset a portion of their energy use. (Short-term)
Already-Projected Amount: Solar photovoltaic (PV) systems convert solar energy into
electricity. The projected power generation30 of residential PV systems at 4,685 homes is 15.9
MW31 in the year 2035, which is enough to fully power these homes.32
Target: The target is 25 MW in the year 2035, which is the equivalent amount of production
to power 7,367 homes.33
GHG Reduction Measure Description: PV systems convert solar energy into electricity.
Producing renewable energy locally through residential, commercial, and industrial PV
systems reduces the need to construct costly new power plants that produce air pollution, use
natural resources, and impact the environment.
The San Diego region has among the highest rates of solar energy production in the nation,
producing an annual average of about 6.5 kWh per square meter per day, according to the
National Renewable Energy Laboratories. A 2006 estimate found that existing PV technology
could supply over 100 percent of the peak electricity demands for San Diego County, and over
half of the total energy load.34 Measure A is to promote the installation of PV systems on single-
family and multi-family homes above the already-projected amount (4,685 homes) by an
additional 2,682 homes, or a total of about 15 percent of homes.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure A.
Responsibility and Implementation: The City of Carlsbad currently participates in three
Property Assessed Clean Energy (PACE) programs: CaliforniaFIRST, FigTREE, and
30 The maximum amount of power produced is also referred to as solar capacity.
31 Solar capacity (MW) was converted into an annual energy total (kWh per year) as follows: The standard assumption
is about 5 hours of production per day per solar system. The capacity was multiplied by 5 hours per day times 365
days per year to get a total production in kWh per year. Therefore, 15.9 MW converts to 29,017,500 kWh per year.
32 Average household energy use was calculated as follows: The California per capita electricity use in 2010 was 2,337
kWh (source: http://www.eia.gov/state/?sid=CA). The average household size in 2010 was 2.65 people per
household (source: http://www.census.gov/newsroom/releases/archives/2010_census/cb11-cn137.html). Therefore,
the average household energy use in 2010 was: 6,193.1 kWh per year.
33 It was assumed that residential PV systems produce the equivalent amount of energy to the amount consumed in each
household on an annual basis.

California HERO. PACE programs provide financing to eligible property owners for
sustainable energy projects, thereby offering a source of funding for residential PV systems.
Property owners can finance PV system installations and energy efficiency improvements
through a voluntary assessment on their property tax bills. Several other financing options are
available to residents, including Federal Housing Financing Administration- (FHFA) insured
Energy Efficient Mortgages, HUD Title 1 Home Improvements Loans, and FHA PowerSaver
Loans.
The city will temporarily suspend residential and commercial solar PV system permit fees. The
city will also on a continuing basis ensure that regulatory provisions—such as complying with
regulations for zoning, structure height, permit submittal and review process, etc.—do not
hinder PV panel installation.
Costs and Benefits:
Private: Private costs would come from the installation and maintenance of a residential PV
system, which can be supported by PACE programs and other incentives. Benefits would
accrue from reduced energy bills and increased property values.
City: City costs would occur from the analysis of potential regulatory barriers and adopting an
ordinance requiring new homes to install PV systems. Revenue would be lost when permit fees
are temporarily suspended.
Measure B: Promote Installation of Commercial and Industrial Photovoltaic Systems
Goal: Promote installation of commercial and industrial PV
systems to produce an additional 10.711.24 MW per year above
projected amounts, or roughly 15 percent of projected
commercial and industrial electricity use, by 2035.
2035 Reduction: 13,3364,457
MTCO2e
Actions: (See also actions A1 and A2 above).
B-1: Adopt a commercial energy conservation ordinance requiring all new nonresidential developments
with more than 50 cars surface parked or on roofs of parking structures to use PV panels over at
least half of the surface/roof-parked cars, or provide equivalent energy conservation/generation by
other means (over and above other requirements). (Short-term)Implement and enforce Title 18,
Chapter 18.30, Section 18.30.130 of the Carlsbad Municipal Code, mandating solar photovoltaic
energy generation systems on new non-residential buildings. (Ongoing)
B-2: Implement and enforce Title 18, Chapter 18.30, Section 18.30.130 of the Carlsbad Municipal Code,
mandating solar photovoltaic energy generation systems on existing non-residential buildings
undergoing major renovations.(Ongoing)Adopt an ordinance requiring existing nonresidential
developments to install PV panels to offset a portion of their energy use. (Mid-term)
Already-Projected Amount: The projected power generation from commercial and industrial
PV systems is 22.3 MW in the year 2035, which is about 30 percent of projected commercial
and industrial electricity use.
July 14, 2020 Item #17 Page 69 of 128
CARLSBAD CLIMATE ACTION PLAN
4-5
Target: The target is the PV production of 33 MW in the year 2035, which is the equivalent
amount of power production to supply about 45 percent of projected commercial and industrial
demand.
GHG Reduction Measure Description: Photovoltaic (PV) systems convert solar energy into
electricity. Measure B promotes the installation of PV systems on commercial buildings and
industrial facilities above the already-projected amount of 22.3 MW, by an additional
11.2410.7 MW. Together with the already-projected amount of power generation, Measure B
would reach the target PV production of 33 MW in 2035.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure B.
Responsibility and Implementation: See Measure A (above) for implementation.Property
owners engaging in new construction and major renovations will be responsible for providing
PV systems. The City is responsible for enforcing the ordinance, as well as encouraging the
voluntary installation of non-residential PV systems through the city website and other means.
Costs and Benefits:
Private: Private costs would result from the installation and maintenance of commercial and
industrial PV systems. Benefits would accrue from reduced energy bills and increased property
values.
City: City costs would occur from removing potential regulatory barriers and preparing
andimplementing and enforcing a nonresidential PV systems ordinance. Revenue would be lost
when permit fees are temporarily suspended.
4.2 Building Cogeneration
Measure C: Promote Building Cogeneration for Large Commercial and Industrial Facilities –
Deleted in CAP Amendment No. 1
Goal: Promote building cogeneration for large commercial and
industrial facilities, with the goal of producing 6.9 MW.
2035 Reduction: 1,067 MTCO2eN/A
This Measures will no longer result in significant GHG reductions due to the high renewable electricity
content associated with SDG&E’s RPS and the CEA CCE.Actions:
C-1: Promote cogeneration by publicizing grant opportunities and financial incentives, such as the Self-
Generation Incentive Program and feed in tariffs for cogeneration systems, for renovations of
existing buildings by posting these on the city’s website and by other means. (Short-term)
C-2: Install cogeneration systems on large city facilities that can benefit from the installation of these
systems, and apply for funding through the Energy Efficiency Financing for Public Sector Projects
program, or other similar funding sources. (Mid to Long-term)
C-3: Require cogeneration systems for large commercial and industrial facilities that have on-site
electricity production, both for new construction and retrofits. (Mid-term)

4-6
Already-Projected Amount: The forecast capacity of building cogeneration systems is 6.9
MW in the year 2035.
Target: The target is to reach the already-projected amount.
GHG Reduction Measure Description: Building cogeneration, also known as combined heat
and power (CHP), is the use of building power stations to simultaneously generate electricity
and heat. Instead of purchasing electricity from a utility and burning fuel in an on-site furnace
to produce needed heat, an industrial or commercial user can use building cogeneration to
provide both electricity and heat in one energy-efficient step. Examples of facilities able to use
building cogeneration include manufacturing plants, hospitals, water and wastewater treatment
facilities,35 and large office buildings.
Building cogeneration reduces building energy costs, provides stability in the face of uncertain
electricity prices, and enhances energy reliability. Building cogeneration also provides the
opportunity to improve critical infrastructure resiliency, by allowing critical facilities to run
without any interruption in service if the electrical grid is impaired. Measure C is to promote
the installation of building cogeneration systems on large commercial and industrial facilities
to reach the projected capacity of 6.9 MW by 2035.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure C.
Responsibility and Implementation: The City of Carlsbad will apply for funding to install
cogeneration systems on city facilities that would benefit from the use of these systems. The
city will also publicize incentives for the construction of cogeneration systems, and require
cogeneration systems for new construction and retrofits of large commercial and industrial
facilities through the permitting process, where the facility has on-site non-renewable
electricity generation.
A number of funding sources exist to provide financial support for the installation of
cogeneration systems. Funding for cogeneration systems for city facilities is available through
the Energy Efficiency Financing for Public Sector Projects program. In addition to city
government buildings, the program also applies to schools and other public or institutional
facilities. There is no minimum loan amount, but the maximum loan amount per application is
$3 million. The interest rate is 1 percent, and loans must be repaid from energy cost savings
within 15 years, including principal and interest. As well, the city will consider use of its
Infrastructure Replacement Funds (IRF) to install feasible cogeneration systems as part of
refurbishment of existing city facilities.
The Self-Generation Incentive Program (SGIP) provides financial incentives for the
installation of new qualifying technologies, including cogeneration, that are installed to meet

all or a portion of the electric energy needs of a facility.36 SGIP is funded by the California
Public Utilities Commission, and administered by the California Center for Sustainable Energy
in SDG&E’s service area. San Diego’s 2014 share is approximately $10 million per year.
Under the SGIP program, cogeneration systems receive an incentive of $1.83 per watt
produced. SDG&E also offers seminars on the benefits of cogeneration and fuel cell options
for large facilities.
For cogeneration systems that produce electricity in excess of the facility’s needs, the state of
California has initiated a feed-in tariff, which provides a cost-based price for renewable energy
produced.

Costs and Benefits:
Private: Private costs would come from the installation and maintenance of building
cogeneration systems, and which could be reduced through funding programs, such as SGIP.
Benefits would accrue from reduced energy bills and increased property values.
City: City costs would come from promoting cogeneration systems, and incorporating the
consideration of cogeneration into the permitting process for commercial and industrial
facilities. Benefits could accrue from reduced energy bills for city facilities that utilize
cogeneration systems.
4.3 Single-family, Multi-family, Commercial, and City
Facility Efficiency Retrofits
Measure D: Encourage Single-Family Residential Energy Efficiency Retrofits
Goal: Encourage single-family residential efficiency retrofits with
the goal of a 50 percent energy reduction compared to baseline
in 30 percent of the total single-family homes citywide by 2035
(approximately 10,000 single-family homes out of a total of
35,000).
2035 Reduction: 1,1327,986 MTCO2e
Actions:
D-1: Publicize available incentive and rebate programs, such as SDG&E’s Residential Energy Efficiency
Program, on the city’s website and by other means. (Short-term)
D-2: Create a citywide “Energy Challenge,” similar to the Department of Energy’s Better Buildings
Challenge, to promote cost-effective energy improvements, while having residents and building
owners commit to reducing energy consumption. (Short-term)
D-3: Adopt a residential energy conservation ordinance, which requires residential property owners to
conduct and disclose an energy audit at the time of major renovations (as defined by the
ordinance), to ensure that homes and residential developments meet specified low cost energy
efficiency measures—such as requisite ceiling insulation, insulated pipes, water heater blankets
and exterior door weather stripping. (Short-term)Implement and enforce Title 18, Chapter 18.30,
Section 18.30.190, mandating energy efficiency measures in existing residential buildings
undergoing major renovations. (Ongoing)
Already-Projected Amount: There is no projection for retrofits that would occur without this
measure.
Target: The target is a 50 percent energy reduction in 30 percent of single-family homes
citywide by the year 2035.
GHG Reduction Measure Description: As single-family homes use a large portion of the
city’s total energy and older homes are substantially less efficient than newly constructed
homes, there is a large opportunity to reduce GHG emissions through the retrofitting of existing
homes. When a single-family homeowner seeks to make major improvements, the owner

4-9
would be required to conduct an energy audit, and meet low-cost energy efficiency measures—
such as changing light bulbs and switches, insulating exposed hot water piping, sealing air
ducts, improving insulation, or installing a “cool roof.” Additional voluntary energy efficiency
measures could include providing weather stripping, promoting natural lighting and
ventilation, and using “smart” thermostats to regulate energy use for heating and cooling.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure D.
Responsibility and Implementation: Homeowners would implement this measure. SDG&E
offers a Residential Energy Efficiency Program, which offers residential customers rebates to
improve the efficiency of appliances, such as water heaters, washers, refrigerators, air
conditioners, building insulating, and ceiling fans. The City will publicize this and related
programs on its website and by other means.
Costs and Benefits:
Private: Private costs would come from homeowners conducting energy audits and
implementing efficiency retrofits. The cost of these retrofits is frequently 1 percent or less of
the total renovation cost. Benefits would occur through reduced energy costs. Rebates are
available as described above.
City: City costs would come from promoting incentive programs, creating an “Energy
Challenge” program, and adopting implementing and enforcing a residential energy
conservation ordinance.
Measure E: Encourage Multi-Family Residential Efficiency Retrofits
Goal: Encourage multi-family residential efficiency retrofits with
the goal of a 50 percent energy reduction in 30 percent of the
projected amount of multi-family homes citywide by 2035
(approximately 5,000 out of a total of 17,000).
2035 Reduction: 3,993351 MTCO2e
Actions: See Measure D (above).
Action D-1: Publicize available incentive and rebate programs, such as SDG&E’s Residential Energy
Efficiency Program, on the city’s website and by other means. (Short-term)
Action D-2: Implement and enforce Title 18, Chapter 18.30, Section 18.30.190, mandating energy
efficiency measures in existing residential buildings undergoing major renovations. (Ongoing)
Already-Projected Amount: There is no projection for retrofits that would occur without this
measure.
Target: The goal is a fifty percent energy reduction in thirty percent of the projected amount
of multi-family homes citywide by the year 2035.
GHG Reduction Measure Description: Multi-family residential retrofits provide an
opportunity to reduce building energy use. Multi-family residential retrofits are similar to the
July 14, 2020 Item #17 Page 74 of 128
4: CAP GHG REDUCTION MEASURES
4-10
single-family retrofits described in Measure D, but can provide increased energy savings; for
example, increasing insulation between residential units benefits both units. Other examples of
potential multi-family residential retrofits energy efficiency improvements include replacing
incandescent and halogen lamps with LED or CFL lamps, installing energy-efficient windows
and efficient appliances, and using “smart” thermostats to regulate energy use for heating and
cooling.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure E.
Responsibility and Implementation: Multi-family residential unit owners would implement
this measure. SDG&E offers a Residential Energy Efficiency Program, which offers residential
customers rebates to improve the efficiency of appliances, such as water heaters, washers,
refrigerators, air conditioners, building insulating, and ceiling fans. The City will publicize this
and related programs on its website and by other means.
Costs and Benefits:
Private: Private costs would come from multi-family residential unit owners conducting
energy audits and implementing efficiency retrofits. Benefits would occur through reduced
energy costs. Rebates are available as described above.
City: City costs would come from promoting incentive programs, and implementing and
enforcing a residential energy conservation ordinance.and creating an “Energy Challenge”
program.
Measure F: Encourage Commercial and City Facility Efficiency Retrofits
Goal: Encourage commercial and city facility efficiency retrofits
with the goal equivalent to a 40 percent energy reduction in 30
percent of commercial square footage citywide and in city
facilities by 2035.
2035 Reduction: 7,57918,377
MTCO2e
Actions:
F-1: Undertake a program of energy efficiency retrofits for city-owned buildings, with the goal of 40
percent reduction in energy use, beginning with retrofits that would result in the most substantial
energy savings. (Short-term)
F-2: Promote available incentive and rebate programs, such as SDG&E’s Energy Efficiency Business
Rebates and Incentives Program, on the city’s website and by other means. (Short-term)
F-3: Implement and enforce Title 18, Chapter 18.21, Section 18.21.155, mandating energy efficiency
measures in new non-residential buildings and existing non-residential buildings undergoing major
renovations. (Ongoing)Adopt a commercial energy conservation ordinance, which requires
property owners to ensure that commercial buildings meet specified energy efficiency measures—
such as requisite heating, ventilation, and air conditioning improvements, service water system
requirements, and improved refrigeration equipment, at the time of conducting major renovations
(as defined by the ordinance). (Short-term)
July 14, 2020 Item #17 Page 75 of 128
CARLSBAD CLIMATE ACTION PLAN
4-11
Already-Projected Amount: There is no projection for retrofits that would occur without this
measure.
Target: The target is equivalent to a 40 percent energy reduction in 30 percent of the projected
amount of commercial square footage and in city facilities.
GHG Reduction Measure Description: Relatively straightforward fixes to commercial and
city-owned buildings can significantly reduce spending on fuel and electricity for commercial
buildings. Examples of retrofits include installing efficient boilers and equipment, installation
of high-quality windows, efficient lighting, and other building energy improvements.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure F.
Responsibility and Implementation: Building owners would implement this measure for
commercial buildings.37 Funding is available through incentive and rebate programs, such as
SDG&E’s Energy Efficiency Business Rebates and Incentives Program. SANDAG is
preparedpreparing an Energy Roadmap for the city, which included energy audits for most city
facilities and will identifiedy energy conservation measures the city can use to reduce energy
use in city municipal operations.38 Funding for city retrofits can be provided through the
Energy Efficiency Financing for Public Sector Projects program, described above in Measure
C. As well, the city will use its IRF to install energy efficiency retrofits as part of refurbishment
of existing city facilities.
Costs and Benefits:
Private: Private costs would come from building owners and business owners implementing
efficiency retrofits. Benefits would occur through reduced energy costs. Costs could be offset
through incentive and rebate programs.
City: City costs would come from retrofitting city facilities, providing resources to help guide
building owners to implement this measure, promoting available incentive and rebate
programs, and adopting implementing and enforcing a commercial energy conservation
ordinance.
37 AB 8021103, the California Nonresidential Building Energy Use Disclosure Program, requires an owner of a nonresidential building 50,000 square feet or larger to benchmark the building’s energy use data and annually disclose
the energy use to the state.prior to the sale of the building, or the lease and financing of the entire building. This
benchmark data can be used to guide implementation of efficiency measures for buildings renovated after a recent
sale.

4.4 Commercial and City Facility Commissioning
Measure G: Promote Commercial and City Facility Commissioning – Deleted in CAP Amendment
No. 1
Goal: Encourage commercial and city facility commissioning, or
improving existing and new building operations, with the goal
equivalent to a 40 percent energy reduction in 30 percent of
commercial square footage citywide and in city-owned buildings
by 2035.
2035 Reduction: 18,377 MTCO2eN/A
This measure is now administered through the utility energy efficiency programs and accounted for in the
legislative business-as-usual projection for state policy and programsActions:
G-1: Promote commissioning programs on the city’s website such as San Diego RCx, and similar
programs for commercial buildings. (Short-term)
G-2: Commission city facilities to improve building operations and reduce energy costs, with a goal of 40
percent energy reduction in 30 percent of city facility square footage. (Mid-term)
Already-Projected Amount: There is no projection for commercial commissioning that
would occur without this measure.
Target: The target is equivalent to a 40 percent energy reduction in 30 percent of existing and
new commercial square footage citywide and in city facilities.
GHG Reduction Measure Description: Commercial commissioning is a systematic process
of ensuring that a building performs according to its design and the occupant’s operational
needs. Commissioning allows the design developed to be successfully constructed and
operated. Examples includes measuring temperatures and flow rates from heating, ventilation,
and air conditioning (HVAC) systems to calibrate to a known standard, as well as reviewing
operations to verify that controls are properly functioning.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure G.
Responsibility and Implementation: The City is responsible for commissioning city
facilities. Building owners would implement this measure for commercial buildings. Programs
exist to offer assistance with the commissioning. San Diego RCx, a SDG&E program, provides
a free engineering study to qualified buildings to identify opportunities to save energy. After
opportunities are identified, the program offers financial assistance to help pay the cost of
implementing measures, which are typically low or no cost. Once implementation is complete,
energy savings are confirmed with the utility, and the program pays the building owner the cost
of the improvements. Commissioning of existing city facilities can occur concurrently with
the 10-year master refurbishments schedule, using IRF.
Costs and Benefits:
July 14, 2020 Item #17 Page 77 of 128
CARLSBAD CLIMATE ACTION PLAN
4-13
Private: Private costs would come from building owners paying for building commissioning,
which may be offset entirely through commissioning programs. Benefits would occur through
reduced energy costs.
City: City costs would come from commissioning city facilities and from promoting
commissioning programs to help guide building owners to implement this measure. Benefits
would occur through reduced energy costs.
4.5 Green Building Code
Measure H: Implement Green Building Measures – Deleted in CAP Amendment No. 1
Goal: Implementation of a 5 percent improvement in energy
efficiency above the City of Carlsbad residential green building
code (based on CALGreen, the statewide green building code),
for new construction.
2035 Reduction: 179 MTCO2eN/A
This Measure is no longer needed because new and future building codes are already more efficient than
the 2013 CALGreen code.Action:
H-1: Adopt residential and commercial energy conservation ordinances requiring a 5 percent
improvement in energy efficiency for residential and nonresidential new construction, above the
existing City of Carlsbad green building code. (Short-term)
Already-Projected Amount: There are no projections for this measure.
Target: The target is a five percent improvement in energy efficiency above the mandatory
requirements set in CALGreen.
GHG Reduction Measure Description: CALGreen, also known as Title 24, is California’s
Building Energy Code. CALGreen requires that new buildings reduce water consumption,
increase system efficiencies, divert construction waste from landfills, and install low pollutant-
emitting finish materials. CALGreen has mandatory measures that apply to nonresidential and
residential construction. The most recent CALGreen code was adopted in 2013 and became
effective in 2014. This measure applies a five percent improvement in energy efficiency above
CALGreen as part of a local Green Building Code.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure H.
Responsibility and Implementation: The City of Carlsbad shall adopt a Green Building Code
with a standard of five percent improvement in energy efficiency above CALGreen, which
would also apply to any subsequent updates of the CALGreen Building Code. The Green
Building Code would apply to new construction within the city.
Costs and Benefits:

Private: Private costs would occur in implementing the improvements in energy efficiency
above the CALGreen code in new construction.
City: There is no cost to the City of Carlsbad, other than adopting the ordinance.
4.6 Efficient Lighting Standards
Measure I: Promote Replacement of Incandescent and Halogen Bulbs with LED or Other Energy
Efficient Lamps
Goal: Replace 50 percent of incandescent and halogen light
bulbs citywide with LED or similarly efficient lighting by 2035. 2035 Reduction: 21,90022 MTCO2e
Actions:
I-1: Replace 50 percent of incandescent or halogen light bulbs in city facilities with LED or similarly
efficient lighting, or follow SANDAG Energy Roadmap recommendations for lighting in city
facilities, whichever results in greater energy savings. (Short-term)
I-2: Promote the use of LED or other energy efficient lamps by publicizing rebate programs and
information from SDG&E on the benefits of the use of LED or other energy efficient lighting on the
city’s webpage. (Short-term)
I-3: Evaluate the feasibility of adopting a minimum natural lighting and ventilation standard, developed
based on local conditions. Demonstrate natural lighting and ventilation features in future city
facility upgrade or new construction. (Mid-term)
Already-Projected Amount: There are no projections for this measure.
Target: The target is to replace 50 percent of incandescent and halogen bulbs citywide with
LED bulbs or similarly efficient lighting by 2035.
GHG Reduction Measure Description: Replace inefficient incandescent and halogen light
bulbs with more efficient light bulbs to reduce the amount of energy needed to power the bulbs,
which will reduce the demand for electricity and thus the amount of GHG emissions created
by the electrical power generation. In November 2019, the California Energy Commission
(CEC) voted to ban the sale of inefficient light bulbs, effective January 2020. Inefficient light
bulbs are defined as any general service lamps with a efficacy of less than 45 lumens per watt.
Under AB 1109 (2007), minimum energy efficiency standards are structured to reduce
statewide electrical consumption by 50 percent or greater from 2007 levels for indoor
residential lighting and by 25 percent or greater from 2007 levels for indoor commercial and
outdoor lighting by 2018. The improved efficiency standards from AB 1109 will help to meet
the goals of this measure. SANDAG is preparingprepared an Energy Roadmap for the city,
which may include lighting replacement recommendations for city facilities. Either the
measures in the Energy Roadmap or the goal of 50 percent of incandescent and halogen light
bulbs will be followed for city facilities, whichever results in greater energy savings.which
included energy audits for most municipal facilities and energy conservation measures the city
can use to reduce energy use in city municipal operations. For existing city facilities, tThe city

has, and will continue to, implement the will also time the lighting efficiency replacements
with the master refurbishment schedule.
Quantification of GHG Emissions Reductions: An estimated 17 percent of residential and
commercial energy nationwide39 and about 25 percent in California40 is used for lighting.
Applied to citywide energy use, 25 percent corresponds to about 78,000 MTCO2e of forecast
emissions in 2035 (from the SEEC community forecast with General Plan land use and
roadways). LED light bulbs reduce energy consumption and therefore GHG emissions by 75
percent compared to incandescent lighting.41 This measure assumes that about 75 percent of
the bulbs citywide are currently incandescent or halogen, and sets the target of replacing half
of these bulbs with more efficient ones by 2035. 42 New construction could set at a goal of 75
percent of bulbs to be LED or similarly efficient. This would overall lead to a 28 percent
decrease in emissions compared to halogen/incandescent bulbs, which equates to emissions
reductions of 21,900 MTCO2e.43 Promotions and rebates, outreach and education, and the
recent CEC decision have all contributed to lighting efficiency replacements in both the
residential and commercial sectors. Therefore, the GHG reductions from this measure are not
significant.
Responsibility and Implementation: Carlsbad’s street lights were replaced in 2011 with
energy-saving induction units, leading to a reduction of approximately 1,240 MTCO2e per year
(already taken into account). The City has been and will continue to replace light bulbs within
City facilities with LED or similarly efficient lighting, as facilities are upgraded. For residential
and commercial customers, SDG&E currently does not offer rebates for the purchase of LED
or similarly efficient lighting, but the City will promote rebates as they come available on its
website and by other means. The City will also provide information on the benefits of the use
of LED and efficient lighting from SDG&E and other sources.
Costs and Benefits:
Private: Private costs would be from purchasing LED light bulbs for new construction, and
replacing existing light bulbs over time. Benefits would be from reduced energy costs and
reduced cost to replace light bulbs (as LED lights last substantially longer).
City: City costs would come from replacing existing inefficient lighting in City facilities with
more efficient light bulbs over time, providing information to homeowners and business

Measure J: New Construction Residential and Commercial Solar Water Heater Installation
Goal: Install solar water heaters or heat pumps on all new
residential and commercial construction. Retrofit up to 30
percent of existing homes and commercial buildings to include
solar water heaters or heat pumps.
2035 Reduction: 11,6042,813
MTCO2e
Actions:
J-1: Promote the installation of solar water heaters and heat pumps by publicizing incentive, rebate and
financing programs, such as PACE programs and the California Solar Initiative for renovations of
existing buildings by posting this information on the city’s website and by other means. (Short-term)
J-2: Adopt residential and commercial energy conservation ordinances requiring new residential and
commercial buildings to install solar water heaters or heat pumps, or use alternative energy (such as
PV-generated electricity) for water heating needs. (Short-term)Implement and enforce Title 18,
Chapter 18.30, Sections 18.30.150 and 18.30.170, mandating alternative water heating
requirements in new residential and non-residential buildings. (Ongoing)
Already-Projected Amount: There are no solar water heaters/heat pumps projected to be
installed.
Target: The target is to install solar water heaters or heat pumps on all new residential and
commercial construction, and retrofit up to 30 percent of existing homes and commercial
buildings to include solar water heaters or heat pumps.
GHG Reduction Measure Description: Solar water heaters use water heated by the sun to
provide domestic and commercial hot water. Solar water heaters reduce the demand for energy
used to heat water. A solar water heater can contribute 30 to 80 percent of the energy needed
for residential water heating.44 Heat pumps are devices that use a small amount of energy to
move heat from one location to another.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure J.
Responsibility and Implementation: The City of Carlsbad currently participates in three
Property Assessed Clean Energy (PACE) programs: CaliforniaFIRST, Ygrene, and California
HERO. PACE programs provide financing to eligible property owners for sustainable energy
projects, including The three PACE programs described in Measure A also provide financing
for the installation of solar water heaters and heat pumps to improve residential energy

ordinance. Retrofit of existing homes could occur through a combination of additional
encouragement and incentives.
Costs and Benefits:
Private: Private costs would occur through the installation of residential and commercial solar
water heaters, which would be passed onto building owners. Benefits would occur through
reduced water heating costs.
City: City costs would occur from adopting implementing and enforcing an ordinance requiring
new homes and commercial buildings to install solar water heaters or heat pumps.

4.8 Transportation Demand Management
Measure K: Promote Transportation Demand Management Strategies
Goal: Promote Transportation Demand Management Strategies
with a goal of achieving a 10 percent increase in alternative
mode use by workers in Carlsbad, for a total of 32 percent
alternative mode use.
2035 Reduction: 23,5496,325
MTCO2e
Actions:
K-1: Adopt aImplement the citywide transportation demand management (TDM) plan, as described in
the General Plan Mobility Element, detailing a mix of strategies to reduce travel demand,
specifically of single occupancy vehicles. SANDAG’s 2012 “Integrating Transportation Demand
Management Into the Planning and Development Process”45 provides a guide to designing and
implementing a TDM plan and will be used as a reference document to develop the city’s TDM
plan. TDM and strategies evaluated in the plan include parking ordinances, subsidized or
discounted transit programs, transit marketing and promotion, carsharing, bikesharing, parking
pricing, and bike parking. (Short-termOngoing)
K-2: Adopt a TDM ordinance, defining a minimum trip generation threshold for nonresidential
development projects. The city will set performance requirements for minimum alternative mode
use based on project type. All projects above the threshold shall submit a TDM plan, which
includes a description of how the minimum alternative mode use will be achieved and maintained
over the life of the project. Potential TDM trip reduction measures can include carpool and vanpool
ridematching services; designated employees as contacts for trip reduction programs; providing a
direct route to transit in coordination with NCTD; developing public-private transit partnerships;
passenger loading zones; pedestrian connections; showers and clothes lockers; carsharing,
bikesharing long–term bicycle parking and shuttle programs. (Mid-term)Implement and enforce
Title 18, Chapter 18.51, mandating TDM improvements and strategies for non-residential
development. (Ongoing)
Already-Projected Amount: There are no projections for this measure. As of 2012,
alternative (non-single occupancy vehicle use—such as working at home, carpooling, transit,
walking and biking) mode use by Carlsbad workers is 22 percent.46 Of these alternative uses,
most workers work at home (44 percent) and carpool (36 percent), followed by public transit
(10 percent), other means (including biking, 6 percent), and walking (5 percent).
Target: The Carlsbad General Plan promotes the use of Transportation Demand Management
(TDM), but does not specify a target goal. This measure specifies a goal of achieving an
additional 10 percent use of alternative modes, for an overall 32 percent alternative mode use
by workers employed in Carlsbad. This is projected to be achieved through 40 percent
alternative mode use by workers in new nonresidential buildings, and 30 percent alternative
mode use by workers in existing (as of 2013) nonresidential buildings.

GHG Reduction Measure Description: Chapter 3 quantifies emissions reductions from the
Carlsbad General Plan due to bikeway system improvements, pedestrian improvements, traffic
calming, parking facilities and policies, and transportation improvements. This measure is
distinct from these reductions because it focuses on TDM, or the application of strategies and
policies to reduce travel demand, or redistribute it in time and space. This measure reduces
VMT by shifting single occupancy vehicle use to alternative modes, reducing the average
commute length, promoting an alternate work schedule, and promoting telecommuting.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure K.
Responsibility and Implementation: The City of Carlsbad will develop implement a TDM
plan describing strategies to reduce travel demand. The city will also develop implement an
ordinance applying to nonresidential developments meeting a specified minimum trip
generation threshold, providing connections to public transportation whenever possible. The
city will facilitate a coordinated effort between local businesses and NCTD to develop a route
expansion and ridership plan wherever feasible. SANDAG’s iCommute program assists
commuters by providing free carpool and ridematching services, a subsidized vanpool
program, the Guaranteed Ride Home program, SchoolPool carpooling programs for parents,
and information about teleworking, all of which can support the city’s TDM goals.
Costs and Benefits:
Private: Private costs could include need for a TDM coordinator for private businesses,
providing on-site facilities (showers, lockers), and shuttle programs. Benefits would accrue
from reduced spending on gasoline, and reduced traffic from less employee commute.
City: City costs would result from developing, implementing, and enforcing a TDM plan and
ordinance. Implementation costs would include conducting an outreach and education
campaign to promote the benefits of TDM.

4.9 Increased Zero-Emissions Vehicle (ZEV) Travel
Measure L: Promote an Increase in the Amount of Zero-Emissions Vehicle Travel
Goal: Promote an increase in the amount of ZEV47 miles
traveled from a projected 15 4.5 percent to 25 percent of total
vehicle miles traveled by 2035.
2035 Reduction: 54,15849,912
MTCO2e
Actions:
L-1: Working with industry partners, construct a “PV to EV” pilot project to install a PV charging station at
a city facility (such as the Faraday Center), to charge city ZEVs. The purpose of the pilot project
would be to evaluate the feasibility of incorporating more ZEV into the city’s fleet. (Short-term)
L-2: Prepare a community-wide charging station siting plan, which evaluates site visibility and exposure,
EV driving ranges, high volume destinations, locations with high ownership or interest in EVs, and
cost of construction. (Short-term)
L-3: Construct ZEV charging stations based on the community-wide charging station siting plan
described in L-2 above. The ZEV charging stations will be funded by grant funds when available,
and the city will post signage directing ZEVs to charging stations. (Mid-term)
L-4: Offer dedicated ZEV parking, and provide charging stations adjacent to ZEV parking as identified in
the community-wide charging station siting plan. (Mid-term)
L-5: Adopt requirements for ZEV parking for new developments. (Short-term)
L-6: Implement and enforce Title 18, Chapter 18.21, Sections 18.21.140 and 18.21.150, mandating
electric vehicle charging infrastructure in new residential and non-residential building and existing
residential and non-residential buildings undergoing major renovations. (Ongoing)Adopt a residential
energy conservation ordinance, similar to Palo Alto, requiring the installation of EV chargers or pre-
wiring in new residential construction and major renovations. (Short-term)
L-7: Update the city’s Fleet Management Program to include a low and zero-emissions vehicle
replacement/purchasing policy. Increase the proportion of fleet low and zero–emissions vehicle miles
traveled to 25 percent of all city-related VMT by 2035. (Short-term)
Already-Projected Amount: According to the EPIC mitigation calculator, 15 4.5 percent of
the vehicle miles traveled in 2035 are projected to be from ZEVs.
Target: The target is to increase the proportion of vehicle miles traveled from 15 4.5 percent
to 25 percent by the year 2035.
GHG Reduction Measure Description: Driving ZEVs reduces carbon emissions by
eliminating direct tailpipe emissions of carbon dioxide and other GHGs. The production of
electricity used to power electric vehicles generates GHGs; however, SDG&E electricity
generates much less GHGs than the direct combustion of fossil fuels. Furthermore, electric
vehicles can be charged at home or the workplace using energy produced by PV panels,
47 Zero-Emissions Vehicle (ZEV) is a vehicle that emits no tailpipe pollutants from the onboard source of power. ZEVs
include electric vehicles, fuel cell vehicles, and plug-in hybrids, when in electric mode.

4-21
eliminating GHG emissions completely, at least for the months when PV panels produce the
full amount of electricity needed for operations. The ability to provide entirely emissions-free
transportation through the use of PV panels to charge ZEVs should be capitalized on whenever
possible.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure L.
Responsibility and Implementation: The city will promote an increase in the amount of
electric vehicle travel by constructing ZEV charging stations using the community-wide station
siting plan. Grant funding for the construction of the ZEV charging stations can come from the
California Energy Commission’s Electric Vehicle Charging Infrastructure grant, or other
similar grant programs. The city would be responsible for operating (including electricity
provision, for stations not using PV panels) and maintaining charging stations.
The city will is also promoteing the use of ZEVs by offering requiring dedicated ZEV parking
and adopting requirements for ZEV parkingcharging infrastructure for new development and
major renovations. The city will create an ordinance requiring the installation of ZEV chargers
or pre-wiring in new residential construction and major renovations.48 Through its Fleet
Vehicle Replacement Fund, the City of Carlsbad will is increasinge the city fleet mix of ZEVs,
hybrids, and other low- or zero-emissions vehicles to increase low and zero–emissions vehicle
miles traveled to 25 percent by 2035.
Costs and Benefits:
Private: The private cost would be the purchase of an electric vehicle and the cost of electricity
to power the electric vehicle, for community members who elect to purchase an electric vehicle.
Costs may also occur from installing EV chargers or pre-wiring into new residential
construction or major renovations. Benefits would accrue from reduced spending on gasoline.
City: City costs would be from planning for, constructing, operating (including providing
electricity, for stations not using PV panels) and maintaining ZEV charging stations, which
may be offset by potential user fees or grants from the California Energy Commission, or other
similar agencies. City costs may occur from developingwould also be from implementing
ordinances to require the installation of ZEV chargers in new residential construction and major
renovations.. City costs may also occur from fleet purchases of ZEV vehicles. Benefits would
accrue from reduced spending on gasoline.
48 Assembly Bill 1092 (2013) requires the Department of Housing and Community Development to propose minimum
building standards for the installation of future electric vehicle charging infrastructure for parking spaces in multi-
family dwellings and nonresidential development.

4.10 Citywide Renewable Projects
Measure M: Develop More Citywide Renewable Energy Projects
Goal: Produce the equivalent amount of energy to power 2,000
homes (roughly equivalent to a 5 percent reduction) by 2035
from renewable energy projects.
2035 Reduction: 4,5802,774 MTCO2e
Actions:
M-1: Conduct a feasibility study to evaluate citywide renewable energy projects and prioritize
accordingly. (Short-term)
M-2: Incorporate renewable energy measures such as PV system installation on city buildings and
parking lots, or microturbine installation on city facilities, with the goal of producing approximately
12,000 megawatt-hours per year. (Mid to Long-term)
M-3: Pursue available funding sources for the construction of renewable energy projects by the city,
such as Energy Efficiency Financing for Public Sector Projects and SGIP. (Mid to Long-term)
Already-Projected Amount: There is no projected amount for this measure.
Target: The target is the production of 12,341 megawatt-hours per year, approximately the
energy required to power 2,000 homes.
GHG Reduction Measure Description: The City of Carlsbad has a number of renewable
energy projects in various stages of planning and development. The Maerkle Reservoir
Hydropower Project, which has been permitted by the Federal Energy Regulatory Commission
(FERC), is estimated to produce about 833 MWh per year. In 2014, Alga Norte Community
Park was outfitted with a PV system in the parking area, which will generate some 360 MWh
of electricity per year. Other planned projects include a second pressure-reducing hydroelectric
generator, similar to the Maerkle Reservoir Hydropower Project, and a potential large PV
system at the Maerkle Reservoir property.
Quantification of GHG Emissions Reduction: The production of 12,341 megawatt-hours per
year was converted into MTCO2e using the 2010 SDG&E coefficient of 742.2 lb CO2e per
megawatt-hour. This corresponds to a reduction of 4,5802,774 MTCO2e.
Responsibility and Implementation: The City of Carlsbad would be responsible for
conducting a feasibility study, determining suitable renewable technologies, siting renewable
projects, and constructing and maintaining the renewable energy projects. Funding sources
include the Energy Efficiency Financing for Public Sector Projects, which includes renewable
energies such as PV systems and other distributed generation technologies, as well as the Self-
Generation Incentive Program (SGIP), as described above in Measure C. As well, the city will
use IRF to install renewable energy systems as part of refurbishment of existing city facilities,
where it is feasible to do so.
Costs and Benefits:
Private: There are no direct private costs from this measure.

City: City costs are planning (including a feasibility study), constructing and maintaining the
renewable facilities, some of which may be offset through the funding sources described above.
Benefits accrue from electricity savings to City through net energy metering.
4.11 Water Utilities System Improvements
Measure N: Reduce GHG Intensity of Water Utilities Supply Conveyance, Treatment, and
Distribution 49
Goal: Reduce the intensity of GHG emissions from water utilities
(including water supply, wastewater, and recycled water)
conveyance, treatment, and distribution by 8 percent by 2035.
2035 Reduction: 5,968713 MTCO2e
Action:
N-1: Improve water utilities (including water supply, wastewater, and recycled water) conveyance,
treatment and distribution, and other system improvements. (Mid to Long-term)
Already-Projected Amount: The goal of an 8 percent reduction by 2035 is the default value
in the EPIC mitigation calculator.
Target: The target is to achieve the already-projected amount.
GHG Reduction Measure Description: This measure estimates emissions reductions from
changes in the efficiency of water utilities (including water supply, wastewater, and recycled
water) conveyance, treatment, and distribution facilities within the City of Carlsbad.50 This
combines improvements in overall system efficiency, the reduction in GHG intensity of
electricity used to move water, wastewater, and recycled water, and replacing potable water
needs with expanded recycled water supply. Carlsbad’s Sewer Master Plan, for example, calls
for eliminating several sewer lift stations and replacing them with gravity pipelines, which
would reduce energy usage.51 The Encina Water Pollution Control Facility exemplifies GHG
reductions from water treatment; the facility currently is able to satisfy 60 percent of its energy
needs through methane capture and cogeneration and has a long-term goal of energy
independence from purchased energy. The 2012 Carlsbad Municipal Water District Recycled
Water Master Plan estimates that, by 2030, recycled water demand could double from 4,100
acre-feet/year to about 9,100 acre-feet/year. Expanding the recycled water system would
appreciably reduce the need for more expensive imported water needs in the future.
49 For purposes of this measure, water utilities include potable water treatment and conveyance, sewer conveyance, and
recycled water treatment and conveyance systems.
50 Note: The GHG reductions from water conservation measures detailed in the 2010 Carlsbad Municipal Water District
Urban Water Management Plan (UWMP) have already been considered in the GHG forecasts. Further GHG reductions may be possible through greater conservation efforts than those outlined in the UWMP, including Ordinance No. 44 (2009); however, these have not been quantified in this CAP.
51 The City is replacing three sewer lift stations, which use a combined total of approximately 6,200 kWh of electricity
per year with gravity pipelines, in addition to other planned rehabilitation upgrades included in the Sewer Master Plan.

4: CAP GHG REDUCTION MEASURES
4-24
Quantification of GHG Emissions Reduction: The EPIC mitigation calculator was used to
quantify emission reductions for Measure N, which estimates wastewater emissions reductions
from methane capture, reductions from water treatment and distribution facilities, and changes
in the supply network, including greater use of recycled water.
Responsibility and Implementation: The City of Carlsbad would be responsible for making
the improvements to water supply conveyance, treatment, and distribution, which could occur
through improvements to the Carlsbad Municipal Water District’s system.
Costs and Benefits:
Private: There would be no private costs for this measure.
City: Costs to the City of Carlsbad are from implementing the improvements to the water
utilities system. Benefits occur by reducing energy costs and having newer water delivery
infrastructure.
Measure O: Encourage the Installation of Greywater and Rainwater Collection Systems
Goal: Encourage the installation of greywater and rainwater
collection systems with a goal of 15 percent of homes by 2035.
2035 Reduction: 1,205137 MTCO2e
Actions:
O-1: Host workshops on greywater and rainwater collection systems through the Carlsbad Municipal
Water District, or partner with existing workshop providers, for homeowners interested in installing
systems suitable for their property. (Mid-term)
O-2: Create a design reference manual, or provide links to an existing one, for the design of greywater
and rainwater collection systems. (Mid-term)
O-3: Evaluate the feasibility of offering a rebate for residential greywater systems that require a permit
to cover the cost of obtaining a permit. (Mid-term)
Already-Projected Amount: There is no projection for this measure.
Target: The target is for 15 percent of single-family homes to have greywater and rainwater
collection systems installed by 2035.
GHG Reduction Measure Description: Greywater is wastewater generated from hand
washing, laundry machines, and showers and baths that have not been contaminated by any
toilet discharge. Greywater can be recycled onsite for toilet flushing and subsurface (below
ground) landscape irrigation using a greywater system. The regulations for the design,
construction and use of greywater systems are in Chapter 16A of the California Plumbing
Code. Some small greywater systems that involve laundry machines or single fixtures only are
exempt from permits. More complicated greywater systems require building permits from the
City. Rainwater harvesting is the practice of collecting rainwater from hard surfaces, such as
July 14, 2020 Item #17 Page 89 of 128
CARLSBAD CLIMATE ACTION PLAN
4-25
roofs, and storing it in barrels or cisterns, which can be used for landscape irrigation. Measure
O is to promote the use of on-site greywater and rainwater collection systems for residences.
Quantification of GHG Emissions Reductions: Nationwide, about seven percent of U.S.
GHG emissions are from water and wastewater service provision to urban populations.52 For
this measure, it was assumed that seven percent of the citywide emissions are from water
provision and wastewater services.53 Therefore, about 32,000 MTCO2e of 2035 emissions are
from water provision and wastewater services.
If maximally pursued, the use of greywater and rainwater collection systems could reduce
water demands by 25 percent on a statewide scale.54 For this measure, it was assumed the 25
percent reduction in water demand would scale to individual houses that implement greywater
and rainwater collection systems. A goal of 15 percent of homes with greywater and rainwater
harvesting systems was chosen. A 25 percent reduction of water use in 15 percent of homes
corresponds to a GHG reduction of about 1,205137 MTCO2e.
Responsibility and Implementation: Homeowners would be responsible for the installation
of greywater and rainwater collection systems. The City of Carlsbad will, through the Carlsbad
Municipal Water District, host greywater and rainwater harvesting workshops, or partner with
existing workshop providers. The City will also reference or develop a greywater and rainwater
collection system design manual and consider offering a rebate for residential greywater
systems that require a permit to cover the cost of obtaining a permit.
Costs and Benefits:
Private: Costs to homeowners would be from constructing and maintaining greywater and
rainwater collection systems. Benefits would accrue over time through water savings.
City: Costs to the City of Carlsbad are from hosting workshops and developing or reviewing
greywater and rainwater collection manuals to adopt.

Goal: Achieve 100% renewable electricity by 2030 for 95% of
the residential bundled load and 85% commercial + industrial
bundled load.
2035 Reduction: 56,207 MTCO2e
Action:
P-1: Continue participation in the Clean Energy Alliance Community Choice Energy program (Ongoing).
P-2 Explore the purchase of renewable energy credits if Community Choice Energy program is not
reaching 2035 goal.
Already-Projected Amount: There is no projection for this measure.
Target: The target is for 95 percent of the bundled residential load and 85 percent of the
bundled commercial plus industrial load to use 100% renewable electricity.
GHG Reduction Measure Description: California Assembly Bill 117 allows local
governments to form Community Choice Aggregations, commonly referred to as Community
Choice Energy (CCE) program. These programs offer an alternative electric power option to
customers with the area currently served by an investor-owned utility. CCEs allow local
jurisdictions to increase the proportion of renewable energy available to customers that, in turn,
lowers the GHG emissions from electricity consumption. Another means to lower electricity-
related GHG emissions is to purchase renewable energy credits as an offset to the consumption
of electricity from non-renewable generation sources.
Quantification of GHG Emissions Reductions: The GHG emissions reductions anticipated
with this measure are derived from the Community Choice Energy Technical Feasibility Study
(prepared by EES Consulting, Inc. and dated March 28, 2019), which was prepared for the
cities of Carlsbad, Del Mar, Encinitas and Oceanside. The study evaluates three renewable
energy portfolio scenarios: an SDG&E equivalent; 100% renewable by 2030; and, 100%
renewable upon inception. The GHG emissions reductions associated with this measure are
beyond the reductions assumed by the state mandated renewable portfolio standard.
Responsibility and Implementation: The Clean Energy Alliance Joint Powers Authority and
its staff are responsible for implementing the Community Choice Energy program. Electricity
customers can choose the proportion of renewable energy they consume (50% or 100%). City
staff will monitor the program participation rates and renewable proportions, amount of
renewable energy procured, and the resulting GHG emissions reductions to determine the need
for purchasing renewable energy credits to meet the 2035 reduction target.
Costs and Benefits:
Private: Costs to electricity customers will be a function of the Clean Energy Alliance rate
structure and the proportion of renewable energy purchased through the program.

4.124.14 Combined Effect of CAP GHG Reduction
Measures and Forecast with CAP
Table 4-1 shows a summary of the CAP GHG reduction measures. While the individual
measures may be implemented over different timescales, for the purposes of calculating their
impact in this section, it was assumed that the effect of all measures would begin in the mid-
term time frame and increase linearly to reach the full reduction potential in the year 2035.
Table 4-2 shows proposed residential energy conservation, commercial energy conservation,
and transportation demand management ordinances adjacent to the applicable reduction
measures.
As a whole, the CAP GHG reduction measures were designed to enable Carlsbad to achieve
its GHG reduction target in the year 2035. The combined GHG reductions from these measures
is 185,919142,918 MTCO2e in 2035, which covers the emissions “gap” identified in Chapter
3. Table 4-23 adds the effect of the CAP GHG reduction measures to the community forecast,
and compares the resulting forecast with CAP GHG reduction measures to emission targets.
As proposed, this CAP meets the emissions targets for both 2020 and 2035. Interim “milestone”
years 2025 and 2030 are presented in Table 4-3 in order for the city to check its progress
towards meeting the 2035 target. Figure 4-1 shows the forecast with CAP reduction measures
compared to the emissions targets to demonstrate that both 2020 and 2035 targets will be met
with the implementation of this CAP.
For this CAP to successfully be implemented, the City of Carlsbad must play a prominent role
in implementing the CAP GHG reduction measures. In addition to responsibility and
implementation covered for each measure in this chapter, the following chapter discusses how
the CAP will be revised and updated in the future to ensure that the targets are met.

Implementation, Monitoring
and Reporting
Chapters 3 and 4 identify a comprehensive set of goals and specific, enforceable measures and
actions that the city will take in order to meet its GHG emissions targets. Implementation and
monitoring are key to ensuring that the city is successful in reaching those targets. The city will
use an adaptive management approach to CAP implementation. Adjustments to management
actions will be made as needed to support continuous improvement based on measured results,
monitoring effectiveness, new technology, or in response to deficiencies in program
assessment results. This chapter describes how the City of Carlsbad will implement the CAP
and monitor and report on its effectiveness, consistent with State CEQA Guidelines Sections
15183.5(b)(1)(D) and (E).
For discretionary projects seeking to use CEQA streamlining provisions, in an environmental
document the city shall refer to the required measures in this CAP as mandatory conditions of
approval or as mitigation. This will enable projects to benefit from CEQA streamlining
provisions, while ensuring that the city can achieve the reduction targets outlined in this plan.
5.1 Implementation

VMT = vehicle miles traveled
Implementation Timeframe: The schedule by which each action is to be implemented,
beginning from the year the CAP is adopted, as follows:
Short-term – one to two years
Mid-term – two to five years
Short to Long-term, or Mid-to Long-term – actions that will begin in the short or mid-
term, but take longer than five years to fully implement.

5.2 Monitoring and Reporting
This CAP serves as a toolkit for the City of Carlsbad to reduce community-wide GHG
emissions and meet emissions targets. Climate action planning, however, is an iterative and
adaptive management process: it requires administration, public outreach, monitoring progress
and measuring results, periodically revisiting assumptions and adjusting provisions when
necessary. Through regular monitoring and measuring the performance of CAP activities, the
city will learn what is working and what is not. This will enable the city to make timely
adjustments to existing measures, replace ineffective actions, and/or add new measures as
changes in technology, federal and state programs, or other circumstances warrant.
Figure 5-1 shows the steps in the process of climate action planning.

the process of climate action
planning, the City of
Carlsbad will follow these
steps:

Administration
Following adoption of this CAP, the city will designate a CAP administrator and form an
interdisciplinary CAP implementation team from within the city organization. The
administrator, in conjunction with the implementation team, will be responsible for initial
program start-up activities and for overseeing implementation, monitoring and reporting of all
actions described in the CAP. The composition of the implementation team may vary from
time to time as needed, but it is expected that core members will include staff from Public

Works, Community and Economic Development, Finance, and Communications departments.
As some of the monitoring and reporting activities will require coordination with other
agencies, the implementation team will need to foster effective partnerships accordingly.
Operating resources for administering the CAP will be provided through the city’s annual
budget process. To maximize efficiency and maintain costs, the city will integrate CAP
implementation activities into existing workloads and programs whenever possible. Potential
private and public funding resources for individual GHG reduction measures are identified in
the measure descriptions in Chapter 4. However, since program incentives and funding sources
change over time, the CAP administrator and Implementation Team will need to keep current
on available resources as GHG reduction measures are implemented.
Education and Outreach
A program of this scope and consequence will require substantial community support in order
to succeed. Key to garnering this support is to raise the level of community awareness through
education and outreach. Most of the individual GHG reduction measures in Chapter 4 include
a promotion and education component. Appendix A provides a listing of internet resources on
a variety of climate change-related topics. In addition to these features built into the CAP, the
city will utilize its website, social media, and other communications channels to provide
information about climate change science and anticipated impacts, and by providing residents
and businesses with information and resources to help them take action. The city’s website
already has a good deal of information related to energy and water efficiency programs, and
other environmental sustainability efforts. This Climate Action Plan is also available on the
city’s website. The city will build upon this base of resources by providing current information
and links to various local, state and federal incentive programs to reduce one’s carbon footprint,
and provide assistance to homeowners, businesses, and contractors seeking to make energy
efficiency improvements.
Monitoring and Reporting
The City of Carlsbad will annually monitor and report on CAP implementation activities. The
annual monitoring report will include implementation status of each action and progress
towards achieving the performance targets of the corresponding emissions reduction measure.
The annual monitoring report will also include information on the status of the federal and state
level emissions reductions measures identified in Chapter 3 of this CAP, as well as any new
efforts that may emerge in the reporting year. The annual report will be presented to the City
Council at a public meeting during which interested parties may comment on the report.
Updating GHG Inventory and the CAP
The city will update the community and government operations inventories for calendar year
2014 for inclusion in the first annual report, and then will update the inventories every three
years thereafter. For continuity, the inventory updates will tally emissions from the same
sectors analyzed in Chapter 2 of this CAP. If an updated inventory reveals that the plan is not
making adequate progress toward meeting the GHG target, or that new technologies and
programs emerge that warrant inclusion in the CAP, the city will adjust the CAP by modifying,
adding, and/or replacing measures as necessary. New opportunities for GHG reductions,
July 14, 2020 Item #17 Page 114 of 128
5: IMPLEMENTATION, MONITORING AND REPORTING
5-18
including new funding sources and the ability to link city reduction actions to the city’s Capital
Improvement Plan, Infrastructure Replacement and Fleet Vehicle Replacement schedules, and
other programs can also be incorporated into future updates of the CAP. Interim “milestone”
targets for years 2025 and 2030 as shown in Table 4-3 will be used to gauge whether the city
is making adequate progress toward meeting the 2035 target. Recommendations to adjust the
CAP may be presented to the City Council as part of the annual report or at any other time
throughout the year as necessary to ensure effective CAP implementation.
5.3 Project Review Thresholds and Checklist
Compliance with CAP
During the course of project review, city will evaluate whether a project is subject to provisions
of this CAP, using the screening criteria below. Once this is established, a project shall comply
with the CAP in one of two ways:
Checklist Approach. The Project Review Checklist below provides direction about
measures to be incorporated in individual projects, which will be used during the normal
development review process. Project features that help a project meet the provisions of
the CAP shall then become part of project conditions of approval.
Self-Developed Program Approach. Rather than use the standard checklist, project
proponents can develop their own program that would result in the same outcome as the
checklist. Appendix E provides a non-exclusive list of potential mitigation measures that
can be applied at the project level to reduce project-level greenhouse gas emissions.
Other measures not listed in the Appendix may be considered, provided that their
effectiveness in reducing greenhouse gas emissions can be demonstrated. The self-
developed program approach and selection of mitigation measures shall be subject to city
review and approval.
CEQA Streamlining
Project Screening Thresholds
The California Air Pollution Control Officers Association (CAPCOA) published various
screening thresholds to guide lead agencies in determining which projects require greenhouse
gas analysis and mitigation for significant impacts related to climate change. Utilizing this
guidance, the City has determined that new development projects emitting less than 900
MTCO2e annual GHG would not contribute considerably to cumulative climate change
impacts, and therefore do not need to demonstrate consistency with the CAP.
The city prepared a “Climate Action Plan Consistency Checklist” and “Guidance to
Demonstrating Consistency with the Climate Action Plan For Discretionary Projects Subject
to CEQA,” which lists the types and sizes of projects that correspond to the 900 MTCO2e
screening threshold. The documents were revised to reflect adoption of CAP ordinances. For
proposed projects above the screening threshold, project proponents shall complete the
Checklist. Table 5-2 lists types and sizes of projects that correspond to the 900 MTCO2e

screening threshold; projects equal to or exceeding these thresholds would be subject to CAP
measures.55

Source: Adapted from California Air Pollution Control Officers Association (CAPCOA). CEQA and Climate Change, Evaluating and Addressing Greenhouse Gas Emissions from Projects Subject to the California Environmental Quality Act (January 2008).
Note: For project types not listed in this table, the need for GHG analysis and mitigation will be made on a project-specific basis, considering the 900 MTCO2e screening threshold.
Project Review Checklist
For proposed projects above the screening thresholds, project proponents shall complete the
CAP Project Review Checklist (similar to that shown in Table 5-3). For each item on the
checklist, project proponents shall indicate whether or not the measure is included as part of
the project, or if it is not applicable. The checklist is designed to meet the targets set for the
measures presented in Chapter 4. The checklist shown in Table 5-3 is preliminary and
illustrative of the items that will be included in the finalized checklist. The city will provide a
final checklist incorporating requirements in ordinances drafted for the CAP.
TABLE 5-3: PRELIMINARY CAP PROJECT REVIEW CHECKLIST

Explanation:
A completed CAP Project Review Checklist, including supporting documentation for
applicable measures, demonstrates a proposed project complies with the CAP.
As an alternative to utilizing the Project Review Checklist, a project proponent may develop a
project-specific GHG emissions reduction program that would achieve the same required GHG
reductions. Appendix E to the CAP provides a non-exclusive list of mitigation measures which
may be considered by a project proponent for inclusion in a project-specific GHG emissions
reduction program. The reduction measures identified in the CAP and Appendix E are non-
exclusive, and other effective reduction measures may be available or become available in the
future. The type, character, and level of mitigation would depend on the project type, size,
location, context, and other factors. The availability of mitigation measures changes over time,
as well, with new technologies, building materials, building design practices, and other
July 14, 2020 Item #17 Page 118 of 128

5-22
changes. Therefore, in developing project-specific reductions measures, the city recommends
that a project proponent refer to current guidance from CAPCOA, ARB, OPR, California
Attorney General, and SANDAG to determine applicable mitigation measures and estimate
their effectiveness (see references in Appendix C).
Updating Project Review Checklist
The Project Review Checklist will be finalized by the City of Carlsbad during the first year of
CAP implementation, and updated as necessary to reflect lessons learned through project
streamlining. Federal, state, and San Diego Air Pollution Control District actions will be
monitored to identify future changes to federal or state standards or guidelines that affect
implementation of the CAP. Any changes to California Environmental Quality Act (CEQA)
and CEQA Guidelines will also be integrated into the Project Review Checklist.

1.0 INTRODUCTION AND BACKGROUND
On Sept. 22, 2015, City of Carlsbad City Council adopted Resolution Nos. 2015‐242 and 2015‐
244, approving the Climate Action Plan (CAP) along with the General Plan Update and Program
Environmental Impact Report (PEIR 13‐02). The purpose of the CAP is to describe how
greenhouse gas (GHG) emissions within the City of Carlsbad will be reduced in accordance with
statewide targets through the implementation of certain measures.
The CAP was adopted as a qualified greenhouse gas reduction plan (Qualified Plan) under
California Code of Regulations Title 14 (hereinafter, “State CEQA Guidelines”) Section
15183.5(b). Compliance with Section 15183.5(b) allows later development projects to use the
CAP for their CEQA GHG analyses. Implementation of the CAP also serves as mitigation for the
City’s 2015 General Plan Update.
In order to be considered a Qualified Plan, Section 15183.5(b)(1) states that the CAP should:
“(A) Quantify greenhouse gas emissions, both existing and projected over a specified
time period, resulting from activities within a defined geographic area;
(B) Establish a level, based on substantial evidence, below which the contribution to
greenhouse gas emissions from activities covered by the plan would not be
cumulatively considerable;
(C) Identify and analyze the greenhouse gas emissions resulting from specific actions
or categories of actions anticipated within a geographical area;
(D) Specify measures or a group of measures, including performance standards, that
substantial evidence demonstrates, if implemented on a project‐by project basis,
would collectively achieve the specified emissions level;
(E) Establish a mechanism to monitor the plan’s progress toward achieving the level
and to require amendment if the plan is not achieving specified levels;
(F) Be adopted in a public process following environmental review.”
The current CAP GHG reduction targets and emissions forecast are based upon the 2005
community GHG inventory, as prepared by ICLEI – Local Governments for Sustainability and
revised by Dyett & Bhatia. The inventory revision, described in Appendix B‐2 of the CAP,
adjusted the vehicle miles traveled (VMT) amounts in response to the newly adopted San Diego
Association of Goverments (SANDAG) Technical White Paper entitled, “Vehicle Miles Traveled
Calculations Using the SANDAG Regional Travel Demand Model,” dated May 2013.
During ongoing CAP monitoring, staff determined that the CAP used an incorrect figure in the
VMT calculations, resulting in an incorrect baseline inventory, targets and forecast. This finding
was presented to the City Council on Jan. 21, 2020 through an informational presentation, at
which time staff noted this error necessitated an amendment to the CAP to be considered a
Qualified CAP pursuant to State CEQA Guidelines Section 15183(b)(1)(A), (C) and (D).

Since the adoption of the CAP in 2015, several things have occurred that would guide any
update or amendment to a CAP. In November 2017, the California Air Resources Board issued
the 2017 Climate Change Scoping Plan that contains new guidance on calculating GHG
reduction targets based upon the statewide mass reduction targets of 40% below 1990 levels
by 2030 and 80% below 1990 levels by 2050. Also, some state and federal policies affecting
GHG reduction efforts have changed, such as the energy efficiency and renewable energy
requirements of the 2019 California Building Code and the Governor’s Executive Order to boost
supply of electric vehicles and charging infrastructure. These policy changes need to be
accounted for when forecasting future GHG emissions in a CAP update or amendment.
More locally, in June 2018, the SANDAG Board of Directors accepted the Regional Climate
Action Planning Framework (ReCAP). The ReCAP seeks to provide guidance on the preparation
of CAPs through regionally consistent approaches, methodologies, and data sources. This policy
and technical guidance include derivation of GHG inventories, targets and forecasts, as well as
calculation of GHG reductions from various potential CAP measures.
Carlsbad city staff, working with University of San Diego’s Energy Policy Initiatives Center (EPIC),
derived a 2012 community GHG inventory consistent with ReCAP guidance. EPIC also followed
the ReCAP in preparing an updated GHG emissions forecast, using 2012 as a baseline and
incorporating the current state and federal policies.
The city’s revised GHG reduction targets were based upon the 2017 Scoping Plan and Table 28
of ReCAP Technical Appendix I, which indicate that the 2020 target is a four percent reduction
below 2012 levels and the 2035 target is a 52 percent reduction below 2012 levels.
Given that the existing CAP underestimates the GHG inventory and forecast, additional GHG
reduction measure(s) are needed to reach the newly derived targets. In November 2019, the
City of Carlsbad joined with the cities of Del Mar and Solana Beach to form the Joint Powers
Authority (JPA) for the Clean Energy Alliance (CEA), a Community Choice Energy (CCE) provider.
The CEA will allow local customers to purchase power from more renewable sources starting in
2021, which will significantly reduce the emissions related to electricity consumption.
On May 12, 2020, the City Council received a CAP Progress Report that noted the incorporation
of the updated inventory, targets and forecast, and the inclusion of CCE as a CAP GHG reduction
measure, would allow the CAP to reach the 2020 and 2035 targets. The CAP amendment
analyzed by this Addendum proposes to implement these revisions. More detail on the
proposed CAP amendment is contained in Section 4.0.
2.0 CEQA REQUIREMENTS
State CEQA Guidelines Sections 15162 through 15164 discuss a lead agency’s responsibilities in
handling new information that was not included in a project’s final environmental impact
report.
July 14, 2020 Item #17 Page 122 of 128

Section 15162 of the State CEQA Guidelines states:
“(a) When an EIR has been certified…for a project, no subsequent EIR shall be prepared for
that project unless the lead agency determines, on the basis of substantial evidence in
the light of the whole record, one or more of the following:
1. Substantial changes are proposed in the project which will require major revisions of
the previous EIR…due to the involvement of new significant environmental effects or
a substantial increase in the severity of previously identified significant effects;
2. Substantial changes occur with respect to the circumstances under which the project
is undertaken which will require major revisions of the previous EIR …due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified significant effects; or
3. New information or substantial importance, which was not known and could no
have been known with the exercise of reasonable diligence at the time the previous
EIR was certified as complete…shows any of the following:
(A) The project will have one or more significant effects not discussed in the
previous EIR;
(B) Significant effect previously examined will be substantially more sever than
shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in
face be feasible and would substantially reduce one or more significant effects of
the project, but the project proponents decline to adopt the mitigation measure
or alternative; or
(D) Mitigation measures or alternatives which are considerably different from those
analyzed in the previous EIR would substantially reduce one or more significant
effects on the environment, but the project proponents decline to adopt the
mitigation measure or alternative.”
Alternatively, where some changes or additions are necessary to the previously certified EIR,
but none of the changes or additions meeting the standards as provided for a subsequent EIR
pursuant to State CEQA Guidelines, Section 15162, then the lead agency is directed to prepare
an Addendum to the Final EIR (State CEQA Guidelines, Section 15164). The Addendum should
include a “brief explanation of the decision not to prepare a subsequent EIR pursuant to Section
15162,” and that “explanation must be supported by substantial evidence” (State CEQA
Guidelines, Section 15164(e)). The Addendum need not be circulated for public review, but may
simply be attached to the Final EIR (State CEQA Guidelines Section 15164(c)).

3.0 DESCRIPTION OF APPROVED PROJECT
The City of Carlsbad CAP, approved along with the General Plan Update and Program EIR on
Sept. 22, 2015, is intended to describe how greenhouse gas (GHG) emissions within the City of
Carlsbad will be reduced in accordance with statewide targets through the implementation of
certain measures.
As stated in PEIR 13‐02, dated June 2015, the CAP, “…includes goals, policies, and actions for
Carlsbad to reduce GHG emissions and address climate change and includes:
An inventory of Carlsbad’s citywide and local government GHG emissions;
Forecasts of future citywide and local government GHG emissions;
A comprehensive, citywide strategy and actions to mange and reduce GHG
emissions, with emission targets through year 2035; and
Actions that demonstrate Carlsbad’s commitment to achieve state GHG
reduction targets by creating enforceable measures, and monitoring and
reporting process to ensure targets are met.”
The current CAP is based upon a revised 2005 community GHG inventory, which as discussed in
Section 1.0 contains incorrect VMT calculations and resulted in incorrect targets and forecast.
The CAP contains 15 GHG reduction measures, as follows:
Measure A – Install residential PV systems
Measure B – Install commercial and industrial PV systems
Measure C – Promote building cogeneration for large commercial and industrial facilities
Measure D – Encourage single‐family residential efficiency retrofits
Measure E – Encourage multi‐family residential efficiency retrofits
Measure F – Encourage commercial and city facility efficiency retrofits
Measure G – Promote commercial and city facility commissioning, or improving building
operations
Measure H – Implementation of Green Building Code
Measure I – Replace incandescent bulbs with LED bulbs
Measure J – New construction residential and commercial solar water heater/heat
pump installation and retrofit of existing residential
Measure K – Promote Transportation Demand Management
Measure L – Increase zero‐emissions vehicle travel
Measure M – Develop more citywide renewable energy projects
Measure N – Reduce the GHG intensity of water supply conveyance, treatment and
delivery
Measure O – Encourage the installation of greywater and rainwater systems
July 14, 2020 Item #17 Page 124 of 128

Each of these measures has a quantified goal (e.g. produce an additional 9.1 megawatts of solar
PV generated power by 2035) and a corresponding 2035 GHG reduction amount. All measures
have between one and seven implementing actions, such as the adoption of an ordinance
requiring solar PV installations. The CAP also contains information on implementation,
monitoring and reporting. The original 2005 inventory and the revised 2005 and 2011 inventory
are included as appendices.
4.0 DESCRIPTION OF PROPOSED CHANGES TO PROJECT
The proposed CAP amendment entails several components:
Use of the 2012 Community GHG inventory
Calculation of 2020 and 2035 targets using the 2012 inventory and guidance from
CARB’s 2017 Climate Change Scoping Plan
Addition of CCE as a GHG reduction measure
Recalculation of pre‐existing CAP measures in light of changed state and federal policies
and the changed electrical generation emissions factor associated with CCE.
The CAP amendment will adjust the appropriate sections of the 2015 CAP to reflect the changes
listed above. Other portions of the CAP will remain intact, except for the correction of a cross‐
references to revised information.
Specifically, the CAP amendment will:
Revise Chapter 1 – “Introduction” with updated background information on global
temperatures and state and federal legislation and regulations
Revise Chapter 2, Section 2.2 – “Community Inventory” by replacing the 2005 and 2011
GHG inventories with a 2012 inventory.
Revise Chapter 3 – “Greenhouse Gas Reduction Target, Forecasts, and Emissions “Gap””
as follows:
o Revise Section 3.1 – “GHG Reduction Target” with updated information on the
California Air Resources Board Scoping Plan guidance
o Revised Table 3‐1: “2005 Emissions and Emissions Targets” with 2012 emissions
and Scoping Plan derived targets
o Revise Sections 3.2 through 3.7 in accordance with the 2012 inventory, 2017
Scoping Plan derived targets, and updated forecast
Revise Chapter 4 – “CAP GHG Reduction Measures” as follows:
o Revise Sections 4.1 through 4.11 by replacing content within tables containing
Goals, 2035 Reductions and Actions for all measures
o Delete Measures A, C and H
o Add a section for the CCE measure (Measure P)
o Revise existing Section 4.12 – “Combined Effect of CAP GHG Reduction Measures
and Forecast with CAP” to include updated text, revise Table 4‐1: “CAP GHG
July 14, 2020 Item #17 Page 125 of 128

Reduction Measures Summary,” delete Tables 4‐2 and 4‐3, and update Figure 4‐
1: “Forecast Community Emissions with CAP Reduction Measures and Targets.”
Delete Appendix B‐1 – “2005 City of Carlsbad Greenhouse Gas Inventory”
Revise and retitle Appendix B‐2 – “2011 Carlsbad Community and Local Government
Operations Greenhouse Gas Inventory Updates” by replacing pages 1 through 10 with
the 2012 GHG inventory technical report.
Figure 1 below shows the GHG inventories, targets, and forecast contained in the proposed CAP
amendment.
Figure 1 – Forecast Community Emissions with CAP Reduction Measures and Targets
5.0 ANALYSIS OF POTENTIAL ENVIRONMENTAL IMPACTS
The use of a new GHG inventory, derivation of new targets, recalculation of GHG reductions
from pre‐existing measures, and establishment of new GHG forecasts are administrative
actions. These actions do not change the activities necessary to carry out CAP GHG reduction
measures and, in and of themselves, would not constitute a project under CEQA. Therefore,
this addendum only discusses the potential environmental impacts of the implementation of
the new CCE measure.
July 14, 2020 Item #17 Page 126 of 128

On December 19, 2019, the CEA JPA approved their CCE Implementation Plan. The
implementation plan, dated December 2019, was approved by the California Public Utilities
Commission (CPUC) on March 16, 2020. The plan details the operations of the CCE, including
how the Clean Energy Alliance will procure electricity for its customers. Section 6.10 of the
implementation plan states:
“CEA will initially secure necessary renewable power supply from its third‐party
electric supplier(s). CEA may supplement the renewable energy provided under the
initial power supply contract(s) with direct purchases of renewable energy from
renewable energy facilities or from renewable generation developed and owned by
CEA. At this point in time, it is not possible to predict what projects might be
proposed in response to future renewable energy solicitations administered by CEA,
unsolicited proposals or discussions with other agencies. Renewable projects that are
located virtually anywhere in the Western Interconnection can be considered as long
as the electricity is deliverable to the CAISO control area, as required to meet the
Commission’s RPS rules and any additional guidelines ultimately adopted by the
Alliance.”
The City of Carlsbad Initial Study form, dated April 2019, includes 20 environmental factors that
should be evaluated for any project, as defined by California Public Resources Code Division 13
Section 21065. The environmental factors of aesthetics, agricultural and forestry resources, air
quality, biological resources, cultural resources, geology and soils, hazards and hazardous
materials, hydrology and water quality, land use and planning, mineral resources, noise,
population and housing, public services, recreation, transportation, tribal cultural resources,
utilities and service systems and wildfire all deal with the potential environmental impact from
a physical development. The environmental factor of energy does require an evaluation of the
project’s potential conflict with or obstruction of “a state or local plan for renewable energy or
energy efficiency.” The greenhouse gas environmental factor requires an evaluation of the
project’s potential “conflict with an applicable plan, policy or regulation adopted for the
purposes of reducing the emissions of greenhouse gases.”
While the implementation plan does anticipate the possibility of procuring electricity from
renewable generation developed and owned by CEA, the timing, location, and scope of these
potential projects are unknown and not reasonably foreseeable. The projects, if located within
California, would be subject to permitting and environmental review, at which time any
potentially significant impact could be identified and addressed. To evaluate all of the possible
project types and the various potential characteristics of the site and surroundings would be
wholly speculative. According to State CEQA Guidelines Section 15145: “If, after thorough
investigation, a Lead Agency finds that a particular impact is too speculative for evaluation, the
agency should note its conclusion and terminate discussion of the impact.”
July 14, 2020 Item #17 Page 127 of 128

With regard to the energy and greenhouse gas environmental factors, the CEA is subject to
CPUC oversight and, therefore, any proposed renewable generation project would need to be
consistent with a state plan for renewable energy or energy efficiency. Locally, CCE is being
added to the CAP for the expressed purpose of lowering GHG emissions through renewable
energy and is inherently consistent. The CCE measure also calls for the purchase of renewable
energy credits (RECs) if needed to reach the 2035 goal. RECs support the construction and
operation of renewable energy generation facilities and are, therefore, also consistent with the
furthering of renewable energy and lowering of GHG emissions.
Therefore, the proposed CAP amendment does not constitute a substantial change in the
project or circumstances involving significant environmental effects or a substantial increase in
the severity of previously identified effects. There is no new information that would indicate
new or increased impacts. The mitigation measures previously included and remaining in the
CAP, and the newly included CCE implementation measure remain feasible.
6.0 CONCLUSION
The proposed CAP amendment is timely and necessary. The changes to state and federal GHG
reduction policies, state guidance on target derivation and the adoption of the SANDAG ReCAP
all provide the opportunity for an updated CAP. The corrections to the original inventory,
targets and forecast are needed to allow the CAP to serve as a CEQA streamlining resource for
development projects under discretionary review. The proposed amendment will allow the CAP
to be a Qualified Plan by meeting the required contents as described in State CEQA Guidelines
Section 15183.5(b)(1).
As discussed in Section 5.0, the inclusion of CCE as a CAP GHG reduction measure will not
create any foreseeable environmental impacts. While there is a potential for future CEA‐
developed renewable energy generation projects, environmental review of potential future
developments would be an impossible task involving a wholly speculative evaluation of
impacts. Also, as discussed in Section 5.0, the proposed CAP amendment does not necessitate a
subsequent EIR because it does not create any of the situations contained in State CEQA
Guidelines Section 15162.

Introduction
1.1 Scope and Purpose
Background and Purpose
The Climate Action Plan (CAP) is designed to reduce Carlsbad’s greenhouse gas (GHG)
emissions and streamline environmental review of future development projects in the city in
accordance with the California Environmental Quality Act (CEQA).
The original CAP, adopted in September 2015, was prepared concurrently with the city’s
updated General Plan and included actions to carry out the General Plan’s goals and policies,
consistent with the Community Vision articulated during Envision Carlsbad. The original CAP
was also correlated with the Environmental Impact Report (EIR) on the General Plan, with the
CAP GHG reduction target synchronized with the EIR. CAP Amendment No. 1, adopted in
May 2020, revised the greenhouse gas inventory, reduction targets and forecast, updated
reductions from existing measures, and incorporated Community Choice Energy as a new
reduction measure (Measure P). An Addendum to the EIR was also prepared.
Community Vision and Environmental Stewardship
Carlsbad has long been a steward of environmental sustainability. In 2007, the Carlsbad City
Council adopted a set of sustainability and environmental guiding principles (Resolution No.
2007-187) to help guide city investments, activities, and programs. Sustainability emerged as
a key theme during the Envision Carlsbad community outreach process, and reflected as a Core
Value of the Community Vision:
Core Value 6: Sustainability. Build on the city’s sustainability initiatives to emerge as
a leader in green development and sustainability. Pursue public/private partnerships,
particularly on sustainable water, energy, recycling, and foods.
The General Plan
The General Plan includes strategies such as mixed-use development, higher density infill
development, integrated transportation and land use planning, promotion of bicycle and
pedestrian movements, and transportation demand management. It also includes goals and
policies to promote energy efficiency, waste reduction, and resource conservation and
1: INTRODUCTION
1-2
recycling. These strategies, goals, and policies would result in GHG reduction compared to
baseline trends.
CAP
The CAP includes goals, policies, and actions for Carlsbad to reduce GHG emissions and
combat climate change and includes:
• An inventory of Carlsbad’s citywide and local government GHG emissions;
• Forecasts of future citywide and local government GHG emissions;
• A comprehensive, citywide strategy and actions to manage and reduce GHG emissions,
with emission targets through 2035; and
• Actions that demonstrate Carlsbad’s commitment to achieve state GHG reduction targets
by creating enforceable measures, and monitoring and reporting processes to ensure
targets are met.
The timeframe for the Plan extends from the date of adoption through 2035.
1.2 Climate Change and Greenhouse Gases Overview
Greenhouse Effect and GHGs
Gases that trap heat in the atmosphere are often called “greenhouse gases” (GHGs). The
greenhouse effect traps heat in the troposphere through a threefold process as follows: Short-
wave radiation emitted by the sun is absorbed by the earth; the earth emits a portion of this
energy in the form of long-wave radiation; and GHGs in the upper atmosphere absorb this
long-wave radiation, emitting some of it into space and the rest back toward the earth. This
“trapping” of the long-wave (thermal) radiation emitted back toward the earth is the underlying
process of the greenhouse effect (Figure 1-1).
Principal GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone
(O3), and water vapor (H2O). Some GHGs, such as CO2, CH4, and N2O, occur naturally and
are emitted to the atmosphere through natural processes and human activities. Since different
gases contribute to the greenhouse effect in different proportions, the term CO2e (carbon
dioxide equivalent) provides the reference frame based on comparison to CO2’s contribution.
The greenhouse effect is a natural process that contributes to regulating the earth’s temperature.
Without it, the temperature of the earth would be about 0°F (−18°C) instead of its present 57°F
(14°C) and unlikely to support human life in its current form.

Carbon Cycle and Global Temperatures
The global carbon cycle is complex and incorporates natural sources of atmospheric carbon
dioxide, including respiration of aerobic organisms, wildfires, and volcanic outgassing, and
sinks such the removal of CO2 from by land plants for photosynthesis, and absorption by the
ocean. Data collected on global GHG concentrations over the past 800,000 years demonstrates
that the concentration of CO2, the principal GHG, has increased dramatically since pre-
industrial times, from approximately below 300 parts per million (ppm) in 1800, to about 353
ppm in 1990, 379 ppm in 2005, and 407 in 2018.1
Increased atmospheric concentrations of GHGs have led to a rise in average global
temperatures. Figure 1-2 shows the increase in global temperatures from 1880 to 2019. While
average global temperatures fluctuate on a yearly basis, the general trend shows a long-term
temperature increase. All of the ten warmest years since 1880 have occurred since the year
2000, and scientists expect the long-term temperature increase to continue as well. The
consensus among climate scientists is that earth’s climate system is unequivocally warming,

and rigorous scientific research demonstrates that anthropogenic2 greenhouse gases are the
primary driver.

Climate Change
Global climate change concerns are focused on the potential effects of climate change resulting
from excessive GHGs in the atmosphere and how communities can mitigate effects and adapt
to change in the short and long term.
Numerous observations document the impacts of global climate change, including increases in
global average air and ocean temperatures, the widespread melting of snow and ice, more
intense heat waves, and rising global average sea level. Scientists have high confidence that
global temperatures will continue to rise in the foreseeable future, largely due to anthropogenic
GHG emissions. In addition to the physical impacts to the environment from increased
temperatures, sea level rise, and more frequent extreme weather events, global climate change
is predicted to continue to cause ecological and social impacts. Ecological impacts of climate
change include greater risk of extinction of species, loss of species diversity, and alteration of
global biogeochemical cycles, which play an essential role in nutrient distribution. The social

impacts of climate change include impacts on agriculture, fisheries, energy, water resources,
forestry, construction, insurance, financial services, tourism and recreation.
Higher temperatures, changes in precipitation, decreased water supplies accompanied by
increased demand, increased risk of wildfire, a greater number of extremely hot days, the
decline or loss of plant and animal species, and other impacts of climate change are expected
to continue to affect Carlsbad. Climate change also has public health impacts. City residents
who are already more vulnerable to health challenges are likely to be the most affected by
climate change. These populations tend to be the young and the old, the poor, and those who
are already sick. Increases in extreme heat events can increase the risk of heat-related illness
or death, or the worsening of chronic health conditions. Food scarcity and higher food prices
from impacts to agriculture can cause increased hunger and reduced availability of nutrition.
The increased frequency of natural disasters such as floods, droughts, wildfires, and storm
surges can cause injury or death, illness, and increases or shifts in infectious diseases.
1.3 California GHG Reduction Legal Framework
California has taken an aggressive stance to reduce GHG emissions in order to combat the
impacts of climate change.
Governor’s Executive Order S-3-05
Executive Order S-3-05 (EO S-3-05) recognizes California’s vulnerability to increased
temperatures causing human health impacts, rising sea levels, and reduced Sierra snowpack
due to a changing climate. The Executive Order established targets to reduce GHG emissions
to 2000 levels by 2010, to 1990 levels by 2020, and to 80 percent below 1990 levels by 2050.
Global Warming Solutions Act of 2006 and CARB Scoping Plans
The Global Warming Solutions Act of 2006 (Assembly Bill 32, or AB 32) codifies the target
set in EO S-3-05 of statewide reductions to 1990 emissions levels by 2020. AB 32 directs the
California Air Resources Board (CARB) to develop and implement a scoping plan and
regulations to meet the 2020 target.
CARB approved the first Scoping Plan in 2008, which provided guidance for local
communities to meet AB 32 and EO S-3-05 targets. The Scoping Plan adopted a quantified cap
on GHG emission representing 1990 emission levels, instituted a schedule to meet the emission
cap, and developed tracking, reporting, and enforcement tools to assist the State in meeting the
required GHG emission reductions. California is currently on track to meet or exceed the AB
32 target of reducing GHG emissions to 1990 levels by 2020.
Executive Order B-3015 (EO B-30-15) established a new GHG emissions reduction target of
40 percent below 1990 levels by 2030 and directed CARB to update the Scoping Plan. In
September 2016, Senate Bill 32 (SB 32) was signed into law and codified EO B-30-15. In
November 2017, CARB published the 2017 Climate Change Scoping Plan, which offers the
framework for achieving the 2030 reductions set forth in EO B-30-15 and SB 32.

1.4 Federal and State Emissions Reductions Strategies
and Standards
Several federal and state standards have been adopted to reduce GHG emissions, in addition to
and in support of the targets set in EO S-3-05 and AB 32.
Federal Standards
The United States Environmental Protection Agency (EPA) regulates and tests gas mileage or
fuel economy in order to deter air pollution in the United States. As the transportation sector
produces approximately 30 percent of GHG emissions in the U.S. as a whole, fuel economy
regulations are an important way to reduce GHG emissions.3 The EPA’s Corporate Average
Fuel Economy (CAFE) standards require vehicle manufacturers to comply with the gas
mileage or fuel economy standards to reduce energy consumption by increasing the fuel
economy of cars and light trucks. Also, in 2007, the U.S. Supreme Court ruled that CO2 is an
air pollutant under the Federal Clean Air Act, confirming that the EPA can regulate GHG
emissions.
State Standards
California Senate Bill 375
SB 375 (2008) requires each Metropolitan Planning Organization (MPO) in the state to adopt
a Regional Transportation Plan (RTP) aimed at achieving a coordinated and balance regional
transportation system, including mass transit, highways, railroads, bicycles, and pedestrians,
among other forms of transit. Each MPO is required to prepare a Sustainable Communities
Strategy (SCS) which sets forth forecast development patterns and describes the transportation
system that achieve the regional GHG emission reduction targets set by CARB.
Governor’s Executive Order S-1-07 (Low Carbon Fuel Standard)
Executive Order S-1-07, the Low Carbon Fuel Standard (LCFS), requires a reduction of at least
10 percent in the carbon intensity of California’s transportation fuels by 2020. The LCFS
requires oil refineries and distributors to ensure that the mix of fuel sold in California meets
this reduction. The reduction includes not only tailpipe emissions but also all other associated
emissions from the production distribution and use of transport fuels within the state.
Renewable Portfolio Standards
California’s Renewable Portfolio Standard (RPS), established in 2002 by the California State
Senate in Senate Bill 1078, accelerated in 2006 and expanded in 2011 through SB X1-2, is one
of the most ambitious renewable energy standards in the country. The RPS requires each
energy provider to supply electricity from eligible renewable energy resources to 33 percent of
the total supply by 2020. In 2015, SB 350 increased the RPS to 50 percent renewable by 2030
and a doubling of energy savings in electricity and natural gas customers. In 2018, SB 100
3 In 2011, GHG emissions from transportation were about 28 percent of the total 6,702 million metric tons CO2
equivalents (Source: http://www.epa.gov/climatechange/ghgemissions/sources/transportation.html)
CARLSBAD CLIMATE ACTION PLAN
1-7
updated SB X1-2 and requires 100 percent of electric retail sales and 100 percent of electricity
procured to serve state agencies be carbon-free by 2045.
Pavley Fuel Economy Standards (AB 1493)
In 2009, CARB adopted amendments to the Pavley regulations to reduce GHG emissions in
new passenger vehicles from 2009 to 2016. The standards became the model for the updated
federal CAFE standards.
Title 24 Building Standards & CALGreen
Title 24 is California’s Building Energy Code, which is updated every three years. In 2010,
Title 24 was updated to include the “California Green Building Standards Code,” referred to
as CALGreen. CALGreen requires that new buildings reduce water consumption, increase
system efficiencies, divert construction waste from landfills, and install low pollutant-emitting
finish materials. CALGreen has mandatory measures that apply to nonresidential and
residential construction. The most recent CALGreen code was adopted in 2019 and became
effective in 2020. CALGreen contains voluntary Tier 1 and Tier 2 levels, which are designed
to exceed energy efficiency and other standards.
1.5 Planning Process
How This Plan Was Prepared
The CAP reflects the city’s commitment to the Core Values presented in the General Plan, and
links the elements of the plan—including Sustainability; Open Space and the Natural
Environment; Access to Recreation and Active, Health Lifestyles; Walking, Biking, Public
Transportation, and Connectivity; and Neighborhood Revitalization, Community Design, and
Livability—with the goal of GHG reduction. The original CAP was prepared in 2013 by City
staff and consultants, with input from the public.
On August 22, 2013 the City of Carlsbad hosted a Community Workshop on the CAP. The
workshop provided an opportunity to present the citywide emissions inventory that had been
completed, and discuss potential emission reduction strategies. Feedback from the Community
Workshop was used to guide the preparation of this document.
Relationship to the California Environmental Quality Act
The California Environmental Quality Act (CEQA) is a statute that requires local agencies to
identify significant environmental impacts of their actions and avoid or mitigate those impacts,
if feasible. In 2007, California’s lawmakers enacted Senate Bill (SB) 97, which expressly
recognizes the need to analyze GHG emissions as part of the CEQA process. SB 97 required
the Governor’s Office of Planning and Research (OPR) to develop recommended amendments
to address GHG emissions as an environmental effect.
In 2010, OPR’s amendments to the CEQA guidelines addressing GHG emissions became
effective. Lead agencies are now obligated to describe, calculate or estimate the amount of
GHG emissions resulting from a project, by using a model or methodology to quantify GHG
1: INTRODUCTION
1-8
emissions resulting from a project or relying on a qualitative analysis or performance-based
standards. The lead agency should determine whether a project’s GHG emissions significantly
affect the environment by considering whether the project’s emissions, as compared to the
existing environmental setting, exceeds a threshold of significance that the lead agency
determines applies to the project, and the extent to which the project complies with the
regulations or requirements adopted to implement a statewide, regional, or local plan for the
reduction or mitigation of GHG emissions. In addition, the lead agency is required to impose
feasible mitigation to eliminate or substantially reduce significant effects.
The CAP will help the city with compliance with CEQA Guidelines Section 15183.5(b):
Tiering and Streamlining the Analysis of Greenhouse Gas Emissions, which became effective
in 2010.4 The required elements of a CAP, as cited in the guidelines, state that a plan for the
reduction of GHG emissions should:
• Quantify greenhouse gas emissions, both existing and projected over a specified time
period, resulting from activities within a defined geographic area;
• Establish a level, based on substantial evidence, below which the contribution to
greenhouse gas emissions from activities covered by the plan would not be cumulatively
considerable;
• Identify and analyze the greenhouse gas emissions resulting from specific actions or
categories of actions anticipated within the geographic area;
• Specify measures or a group of measures, including performance standards, that
substantial evidence demonstrates, if implemented on a project-by-project basis, would
collectively achieve the specified emissions level;
• Establish a mechanism to monitor the plan’s progress toward achieving the level and to
require amendment if the plan is not achieving specified levels;
• Be adopted in a public process following environmental review.
The CAP is intended to fulfill these requirements. The CAP also contains a Project Review
Checklist, which allows for streamlined review of GHG emissions for projects that demonstrate
consistency with the CAP, as described in CEQA Guidelines Section 15183.5(b).
Relationship to General Plan and Future Projects
Carlsbad’s approach to addressing GHG emissions within the General Plan is parallel to the
climate change planning process followed by numerous California jurisdictions. A General
Plan is a project under CEQA, and projects under CEQA are required to estimate CO2 and other
GHG emissions, as described above. According to the Attorney General, “in the context of a
4 15183.5(b) of CEQA Guidelines states, “Plans for the Reduction of Greenhouse Gas Emissions. Public agencies may
choose to analyze and mitigate significant greenhouse gas emissions in a plan for the reduction of greenhouse gas
emissions or similar document. A plan to reduce greenhouse gas emissions may be used in a cumulative impacts analysis as set forth below. Pursuant to sections 15064(h)(3) and 15130(d), a lead agency may determine that a
project’s incremental contribution to a cumulative effect is not cumulatively considerable if the project complies with
the requirements in a previously adopted plan or mitigation program under specified circumstances.”
CARLSBAD CLIMATE ACTION PLAN
1-9
general plan update, relevant emissions include those from government operations, as well as
from the local community as a whole. Emissions sources include, for example, transportation,
industrial facilities and equipment, residential and commercial development, agriculture, and
land conversion.” The CAP is designed to provide discrete actions to operationalize the General
Plan policies that help with GHG reduction, as well as outline additional actions to help meet
GHG reduction targets. The preparation of a CAP is also consistent with CEQA Guidelines
Section 15183.5 that allows jurisdictions to analyze and mitigate the significant effects of GHG
at a programmatic level, by adopting a plan to reduce GHG emissions.
Project-specific environmental documents prepared for projects consistent with the General
Plan may rely on the programmatic analysis contained in the CAP and the EIR certified for the
Carlsbad General Plan. The thresholds presented in Section 5.3 present a clear method for
determining the significance of GHG emissions for future projects.
1.6 How to Use This Plan
The CAP is intended to be a tool for policy makers, community members and others to guide
the implementation of actions that limit Carlsbad’s GHG emissions. Ensuring that the
mitigation measures in the CAP translate from policy language to on-the-ground results is
critical to the success of the CAP. Chapter 5 describes how the city will review development
projects to achieve the GHG reduction measures in Chapter 4, consistent with state CEQA
Guidelines. This chapter also outlines how the city will monitor progress in reducing emissions,
and periodically revisit assumptions and key provisions of the plan.

Emissions Inventory
This chapter identifies the major sources and the overall magnitude of greenhouse gas (GHG)
emissions in Carlsbad, pursuant to Sections 15183.5(b)(1)(A) and 15183.5(b)(1)(C) of the state
CEQA Guidelines. The City of Carlsbad prepared an inventory for communitywide GHG
emissions in 2012, 2014 and 2016, the latter of which was provided through the San Diego
Association of Government’s (SANDAG) Regional Climate Action Planning (ReCAP)
program. The city also prepared a 2005 and 2011 inventory of government operations.
Appendix B-1 provides the communitywide inventories in detail and Appendix B-2 contains
the government operations inventories, both of which are summarized in Section 2.2 and 2.3
in this chapter, respectively.
The inventory follows the standards developed by the International Council for Local
Environmental Initiatives (ICLEI) for community and government operations GHG
inventories. The inventory methodology is described first, followed by the inputs, and results.
2.1 Methodology
The community inventories cover all direct GHG emissions5 from sources within the
boundaries of the City of Carlsbad, including fuel combusted in the community and direct
emissions from landfills within the community. Indirect emissions associated with the
consumption of energy (such as electricity, with no end point emissions) that is generated
outside the borders of the city are also included. The U.S Community Protocol for Accounting
and Reporting of Greenhouse Gas Emissions (U.S. Community Protocol), published by ICLEI
USA, requires a minimum of five basic emissions-generating activities to be included in
Protocol-compliance community-scale inventories. The emissions from off-road transportation
(e.g. lawn and garden, construction and industrial equipment) are considered in the inventories.
5 GHGs considered in the report are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons.
The emissions have been converted to carbon dioxide equivalents (CO2e), which converts the three other GHGs into
the equivalent volume of carbon dioxide.
1: INTRODUCTION
2-2
The seven emissions-generating activities included in the community inventories are:
• On-Road Transportation;
• Electricity;
• Natural Gas;
• Solid Waste;
• Off-Road Transportation;
• Water; and
• Wastewater.
As the city has much greater ability to influence its own operations, the government operations
inventory is presented separately, and covers direct emissions from sources the City of
Carlsbad owns and/or controls. This includes mobile combustion of fuel for city vehicles and
the use of natural gas to heat city buildings. Indirect emissions associated with the consumption
of electricity, steam, heating or cooling for city operations that are purchased from an outside
utility are also included. All other indirect emissions sources, including employee commutes
and the decomposition of government-generated solid waste, are not included as part of the
local government operations, but rather counted in the community inventory. The government
operations inventory covers emissions from the following sectors:
• Buildings and Facilities;
• Vehicle Fleet;
• Public Lighting; and
• Water and Wastewater Transport within city borders
The majority of emissions are calculated using activity data and emissions factors. Activity
data refers to a measurement of energy use or another GHG-generation process, such as
residential electricity use, or vehicle miles traveled. Emissions factors are used to convert
activity data to emissions, and are usually expressed as emissions per unit of activity data (e.g.
metric tons carbon dioxide [CO2] per kilowatt hour of electricity). To estimate emissions, the
following basic equation is used:
[Activity Data] x [Emissions Factor] = Emissions
As an example, multiplying the total amount of residential electricity use (activity data,
expressed in kilowatt-hours) by the emissions factor (expressed as CO2e emissions per
kilowatt-hour) produces the emissions in CO2e from residential energy use. Table 2-1 below
describes data sources for estimating activities and emissions factors.

1: INTRODUCTION
2-4
Certain emissions that occur in the city are not counted in the community inventory. For
example, emissions related to the Encina Power Plant are not included in Carlsbad’s GHG
inventory. The reason is as follows: embodied emissions, such as those resulting from power
generation that is produced locally but distributed regionally, are not covered in Carlsbad’s
inventory, in accordance with ICLEI standards. These emissions are included at the points
where energy is consumed (some of which are in Carlsbad) rather than where it is simply produced—otherwise emissions would either be double counted, or if only counted at the
production source, electricity consumption (which is the second largest contributor to GHG)
in climate action planning would be meaningless.
The McClellan-Palomar airport is county owned and operated, and is outside of the city’s
jurisdiction. The city has little, if any, influence over airport operations, and emissions
associated with airport flight operations are excluded because they occur in a regional context.
For transportation trips that originate or end in Carlsbad, emissions for half of the entire trip
are included, and not just for the miles traveled within Carlsbad; however, trips that just pass
through Carlsbad are excluded, as their emissions would be reflected at their trip ends.6
Furthermore, although pass-through trips contribute a substantial amount to VMT totals, the
city and Carlsbad community has limited ability to influence them.
2.2 2012 Baseline Community GHG Inventory
GHG Emissions By Category
As discussed in Section 2.1, a GHG inventory describes the emissions in various categories for
a given calendar year. Some of the inputs, such as electricity and natural gas, are based directly
on consumption data. Others, such as on-road transportation, are based upon model outputs. In
order to determine a community’s GHG emissions reduction targets, and its consistency with
state reduction targets, a baseline GHG inventory is needed. The City of Carlsbad is using the
2012 community GHG inventory as its baseline for the purpose of deriving GHG reduction
targets. A detailed description of the community GHG inventory, including methods and
inputs, is contained in Appendix B-1.
6 For example, for a trip that begins in downtown San Diego and ends in Carlsbad, the entire trip length is calculated for
that trip. Half of the entire trip length is assigned to Carlsbad, and the other half is assigned to the City of San Diego.
Using half the trip length is standard SANDAG methodology for assigning regional VMT to a particular city.

communitywide GHG emissions. However, more detailed information is available to
characterize GHG emissions by source and sector. The city has the ability to directly influence
emissions from government operations, and can provide community leadership in reducing
GHG emissions. As described before, the four sectors included in the government operations
inventory are buildings and facilities, vehicle fleet, public lighting, and water and wastewater
transport.

VEHICLE FLEET
The inputs for this sector are all vehicles used by the city. The key data used are fuel consumed
and VMT, broken out by model year, vehicle type, and fuel type. CACP uses fuel consumption
to calculate CO2 emissions and VMT to calculate NO2 and CH4 emissions.
Although the vehicle fleet data from the city was broken down by department, the inputs were
loaded into CACP as a single set for the entire city due to the time-consuming nature of
processing and entering this very detailed information.
Table 2-9 summarizes the inputs by vehicle and fuel type. Gasoline accounted for the largest
amount of fuel consumption (167,345 gallons) and greatest vehicle miles traveled (1,965,416
VMT).

This sector covers electricity consumed from three sources: traffic signals, streetlights, and
other outdoor lighting. As shown in Table 2-10, streetlights make up the great majority of
electricity consumption in this sector. Between 2005 and 2011, the city retrofitted its existing
streetlights with more energy-efficient lamps.

Greenhouse Gas Reduction
Target, Forecasts, and
Emissions “Gap”
This chapter describes the greenhouse gas (GHG) reduction targets provided by state law,
provides a baseline forecast of community GHG emissions, and models forecasts of future
community and local government GHG emissions through 2035. The chapter also quantifies
GHG reductions from (1) state and federal actions and (2) the updated Draft General Plan
policies and actions, and applies these reductions to the community forecast. The emissions
“gap” between the forecasts (with GHG reductions) and the emissions targets is addressed by
the Climate Action Plan (CAP) GHG reduction strategies in Chapter 4.
3.1 GHG Reduction Target
Statewide GHG Reduction Targets and 2017 CARB Scoping Plan
Executive Order S-3-05 (EO S-3-05) and the California Global Warming Solutions Act of 2006
(AB 32 and SB 32) provide the basis for the CAP’s GHG emissions targets. Collectively they
commit California to reduce its GHG emissions to 1990 levels by 2020, to 40 percent below
1990 by 2030, and to 80 percent below 1990 levels by 2050.
CARB first approved the Scoping Plan in 2008, which provides guidance for local
communities to meet AB 32 and EO S-3-05 targets. The Scoping Plan recommended “a
greenhouse gas reduction goal for local governments of 15 percent below today’s levels by
2020 to ensure that their communitywide emissions match the state’s reduction targets.7 . The
2014 First Update to Scoping Plan repeated that emissions reduction target and provided
guidance for local governments to develop post-2020 GHG reduction targets. It stated that
“there is a need for local government climate action planning to adopt mid-term and long-term
7 CARB 2008. Climate Change Scoping Plan. Pursuant to AB 32 the California Global Warming Solutions Act of 2006,
pg. ES-5.

reduction targets that are consistent with…the statewide goal of reducing emissions 80 below
1990 levels by 2050.”8
CARB’s 2017 Climate Change Scoping Plan recommended statewide targets of “no more than
six metric tons CO2e per capita by 2030 and no more than two metric tons CO2e per capita by
2050.”9 These goals are based upon the 2030 and 2050 goals of 40 percent and 80 percent
reductions below 1990 levels and the projected population for those years. Using the statewide
GHG inventories, percentage reductions can be derived for various baseline years
Total Carlsbad GHG emissions from the 2012 inventory were 977,000 MTCO2e per year.
Therefore, the 2020 target under State guidance is a 4 percent reduction from 2012 emissions,
which corresponds to a target of 939,000 MTCO2e. The 2030 target would be 42 percent below
2012 levels and the 2050 goal would be 81 percent below 2012 levels. While CARB’s Scoping
Plan does not specifically set target levels for intermediate years between 2030 and 2050, the
Scoping Plan recommends a linear progression in annual GHG emissions reductions to meet
the final targets.
The horizon year for this CAP is 2035, corresponding with the General Plan horizon. The CAP
uses a linear trajectory in emissions reductions between 2030 and 2050 to determine the 2035
target. Table 3-1 summarizes these emissions targets and the percentage reduction from 2012
emissions.

3.2 Business as Usual Forecast
The first step in projecting GHG emissions is to calculate the business as usual forecast (BAU).
The BAU forecast estimates community emissions through the year 2035, based on the growth
in emissions in the absence of any new policies or programs. The BAU calculation relies upon
the latest data available, as well as the most recent projections for population, housing and job
growth. The BAU calculation typically represents a linear extrapolation of the most recent data,
holding other variables constant.

The BAU includes emissions projections in the following categories:
• On-road Transportation
• Electricity
• Natural Gas
• Solid Waste
• Off-road Transportation
• Water
• Wastewater
Methodology
The Series 14 Regional Growth Forecast included in the SANDAG 2019 Federal Regional
Transportation Plan was used to obtain the population and job growth in Carlsbad. As of March
2020, SANDAG Series 14 Growth Forecast does not have a breakdown of the number of jobs
by employment type (e.g. construction, agriculture) for each jurisdiction. Therefore, the ratio
of the number of jobs by each employment type to total number of jobs from SANDAG Series
13 Growth Forecast were applied to the job forecast from Series 14. The BAU projections of
926,000 MTCO2e for the Carlsbad community GHG emissions fall below the 2020 target
emissions level of 939,000 MTCO2e. Therefore, the next steps in the projections of emissions
only include a forecast for 2035.
Table 3-2 shows the population and job growth projections for 2035.

On-Road Transportation
Emissions related to on-road transportation are based upon the vehicle miles traveled (VMT)
and the average vehicle emission rate for the San Diego region. VMT is calculated using the
SANDAG Activity-Based Model and the Origin-Destination (O-D) method. 2035 VMT
projections are estimated from extrapolating SANDAG Series 14 2016 VMT data according
to service population. The service population is the sum of population and jobs, which is
projected to be 207,940 in 2035. With an average annual VMT of 1,231,554,425 miles, and an
average vehicle emission rate of 361 pounds of CO2e per mile, the projected 2020 emissions
from on-road transportation are 452,000 MTCO2e and 2035 emissions total 445,000 MTCO2e.

1: INTRODUCTION
3-4
Electricity
Emissions projections from the residential electricity sector are based upon the per capita
electricity use on 2014 (2,159 kWh per person per year) multiplied by the SANDAG Series 14
population forecast. The commercial and industrial emissions projections are based upon per-
job electricity consumption on 2016 (6,936 kWh per commercial job per year and 10,126 kWh
per industrial job per year) multiplied by the SANDAG Series 13 job growth forecast. The
projected 2020 emissions from electricity are 274,000 MTCO2e and 2035 emissions total
296,000 MTCO2e.
Natural Gas
The emissions projections for natural gas are calculated similar to those for electricity. Per
capita consumption for 2016 (118 therms per person per year, 151 therms per commercial job
per year, and 126 therms per industrial job per year) multiplied by population and job growth
forecasts. The projected 2020 emissions from natural gas are 137,000 MTCO2e and 2035
emissions total 147,000 MTCO2e.
Solid Waste
The emissions from solid waste disposal are based upon the per capita disposed in 2016 (3.5
kilograms per person per day) multiplied by forecasted population growth. The projected 2020
emissions from solid waste are 36,000 MTCO2e and 2035 emissions total 37,000 MTCO2e.
Off-Road Transportation
The emissions from off-road transportation include four categories: lawn and garden
equipment, light commercial equipment, construction and mining, and industrial. Lawn and
garden equipment include sources such as lawn mowers, chainsaws and leaf blowers. Light
commercial equipment includes sources such as generators and pumps. The construction and
mining emissions sources include excavators, off highway tractors and paving equipment.
Industrial equipment sources include forklifts, aerial lifts and sweepers. These emissions are
derived from several models, such as OFFROAD2007 and RV2013, and the CARB In-Use
Off-Road Equipment 2011 Inventory. The projected 2020 emissions from off-road
transportation are 15,000 MTCO2e and 2035 emissions total 19,000 MTCO2e.
Water
The emissions from water are based upon the 2016 per capita water consumption (141 gallons
per person per day for potable water and 32 gallons per person per day for recycled water)
multiplied by forecasted population growth. The projected 2020 emissions from water are
9,000 MTCO2e and 2035 emissions total 9,000 MTCO2e.
Wastewater
The emissions from wastewater are based upon the 2016 per capita wastewater generation (53
gallons per person per day) multiplied by forecasted population growth. The projected 2035
emissions from wastewater are 3,000 MTCO2e and 2035 emissions total 3,000 MTCO2e.

Results
Table 3-3 shows the emissions from the business-as-usual community forecast for each
sector—residential, commercial, industrial, transportation, solid waste, landfill, and
wastewater—and the sum total community emissions.
The greatest projected emissions continue to be from the on-road transportation category,
which accounts for 48.9 percent of emissions in 2020 and 46.5 percent in 2035. Electricity
emissions are the next largest category, with 29.6 percent of emissions in 2020 and just under
31 percent of the total in 2035. Emissions from solid waste, off-road transportation, water and
wastewater remain relatively low compared to other categories.
The BAU projections of 926,000 MTCO2e for the Carlsbad community GHG emissions fall
below the 2020 target emissions level of 939,000 MTCO2e. Therefore, the next steps in the
projections of emissions only include a forecast for 2035.

3.3 Government Operations Forecast
Methodology
The SEEC government operations forecast, which is a subset of the community forecast, covers
direct emissions from the sources the City of Carlsbad owns and/or controls. The emissions
from government operations are included in the totals shown in Table 3-4 and Figure 3-4 above.
This section separates out emissions from government operations for accounting purposes. The
government operations forecast includes mobile combustion of fuel for city vehicles and the
use of natural gas to heat city buildings. Indirect emissions associated with the consumption of
electricity, steam, heating, or cooling for city operations that are purchased from an outside
utility are also forecast. All other indirect emissions sources, including employee commute and
the decomposition of government-generated solid waste, are not included as part of the local
government forecast, but rather are counted in the community forecast. The government
operations inventory covers emissions from the following sectors:
• Buildings and Facilities
• Vehicle Fleet
• Public Lighting
• Water Delivery Facilities
• Wastewater Transport
The government operations forecast uses 2005 inventory to represent baseline emissions, and
the 2011 inventory to provide an intermediate value to adjust the model.
Within each sector, certain types of emissions are assumed to scale with population growth,
projected to grow at 0.9 percent annually through 2035, while other types of emissions are
expected to remain constant or decrease with efficiency improvements. The following sections
describe the assumptions underlying the forecast growth rates for each government operations
sector.
Buildings and Facilities
The 2005 and 2011 inventories of emissions from all buildings and facilities operated by the
city were used to determine the future growth for this sector. The natural gas and electricity
demands were assumed to scale with population for departments such as Police, Fire, and Parks
and Recreation, while others, such as Administration and Utilities, would remain staffed at
current levels. These growth rates were then combined to determine an aggregate annual
growth rate of 0.7 percent, which was applied to the buildings and facilities sector.
CARLSBAD CLIMATE ACTION PLAN
3-7
Vehicle Fleet
An estimate of the growth in the number of City employees was used to determine City fleet
use. The growth in fleet emissions beyond 2011 was estimated by assuming—similar to the
Buildings and Facilities sector—that certain departments would scale with population growth,
while others would remain staffed at current levels. These growth rates were then combined to
determine an aggregate annual growth rate of 0.6 percent, which was applied to the city fleet
sector.
Public Lighting
From 2005 to 2011, electricity use for streetlights decreased approximately 4 percent due to
the installation of some energy-saving induction streetlights. Following the completion of the
installation of all induction streetlights, the City’s electricity demand for streetlights was
further reduced, which is reflected in the forecast energy demands for this sector.
Water Delivery and Wastewater
The increased demand for energy usage for water delivery and wastewater was assumed to be
proportional to the amount of water delivered by the Carlsbad Municipal Water District
(CMWD), as projected in the 2010 Urban Water Management Plan (UWMP). CMWD’s
service area covers about 85 percent of the City, and it was assumed that water and wastewater
usage in the remaining 15 percent of the City, served by Olivenhain Municipal Water District
and Vallecitos Water District, would follow similar water use patterns as outlined in the 2010
UWMP.
Results
The city operations forecast for 2020 and 2035 is shown by sector in Table 3-5. Government
operations emissions are projected to decrease from the 2011 inventory total of 8,205 MTCO2e
to 5,185 MTCO2e in 2020. The decrease in emissions is primarily due to the implementation
of the RPS and the fuel efficiency gains from Pavley I standards. Emissions are forecast to then
increase at a low rate through the year 2035 to 5,922 MTCO2e, due to projected increases in
city staff in select departments to accommodate an increased need for city services.
The relative contribution of each sector to the total city operations emissions is generally
constant over time. The two largest emissions sectors are buildings and facilities, comprising
about 40 percent of total emissions, and fleet emissions, which are approximately 33 percent
of the total emissions. Streetlights are about 15 percent of total emissions, followed by
wastewater facilities at 8 percent, and water delivery facilities at 1 percent. Overall,
government operations emissions are forecast to remain a small portion of community
emissions, about 0.9 percent in 2020 and 1 percent in 2035. Chapter 4 discusses mitigation
measures that will reduce government operations emissions.

3.4 GHG Reductions to Community Forecast from Federal
and State Actions
Methodology
The next step in projecting GHG emissions is the consideration of GHG reductions from state
and federal actions. This projection is known as the legislatively-adjusted BAU since it still
lacks any potential GHG reductions from local policies and programs.
The federal and state actions included in the legislatively-adjusted BAU include the following:
• Federal and California Vehicle Efficiency Standards
• California Energy Efficiency Standards
• California Solar Policy, Programs and 2019 Mandates
• Renewable Portfolio Standard
Federal and California Vehicle Efficiency Standards
The federal and California vehicle efficiency standards vary by type of vehicle. For passenger
cars and light-duty vehicles, the applicable standards are the Federal Corporate Average Fuel
Economy (CAFE) standards and California Advanced Clean Car (ACC) Program. The CAFE
standards are developed by the U.S Department of Transportation’s National Highway
Transportation Safety Administration (NHTSA) and regulate how far vehicles must travel on
a gallon of fuel. The ACC program was adopted by CARB and combined the control of smog-
causing pollutants and GHG emissions into a single coordinated package of regulations.
For heavy-duty vehicles (heavy-duty trucks, tractors, and buses), the applicable regulations are
the U.S. Environmental Protection Agency’s (US EPA) Phase-I GHG Regulation and CARB
Tractor-Trailer GHG Regulation. The US EPA regulation was developed in coordination with
the NHTSA and calls for GHG emissions and fuel economy standards. The CARB regulation
CARLSBAD CLIMATE ACTION PLAN
3-9
reduces GHG emissions by improving aerodynamic performance and reducing the rolling
resistance of tractor-trailers. The reductions projected from the federal and California vehicle
efficiency standards total 113,968 MTCO2e in 2035.
California Energy Efficiency Programs
In September 2017, the California Public Utilities Commission (CPUC) adopted energy
efficiency goals for ratepayer-funded energy efficiency programs (Decision 17-09-025); these
went into effect in 2018. The sources of the energy savings include, but are not limited to,
rebated technologies, building retrofits, behavior-based initiatives, and codes and standards.
The reductions projected from the California energy efficiency programs total 19,110 MTCO2e
in 2035.
California Solar Policy, Programs and 2019 Mandates
California has several policies and programs to encourage customer-owned, behind-the-meter
PV systems, including the California Solar Initiatives, New Solar Home Partnership, Net
Energy Metering, and electricity rate structures designed for solar customers. The California
Solar Initiative is the solar rebate program for customers of the investor-owned utilities,
including SDG&E. The New Solar Home Partnership provides financial incentives and other
support to home builders to encourage the construction of new, energy efficient solar homes.
This assistance terminates on December 31, 2021. Net Energy Metering provides utility
customers a credit for the unused electricity produced by their solar system. The new California
2019 Building Energy Efficiency Standards, which went into effect on January 1, 2020, require
all newly constructed single-family homes, low-rise multi-family homes, and detached
accessory dwelling units (ADUs) to have PV systems installed, unless the building receives an
exception. The reductions projected from the California solar policy, programs and 2019
mandates total 37,125 MTCO2e in 2035.
Renewable Portfolio Standard
SB 100, the 100 Percent Clean Energy Act of 2018, adopts a 60% RPS for all of California’s
retail electricity suppliers by 2030; this increased the RPS standard from 50% to 60%. The
legislation also provides goals for the intervening years before 2030 and establishes a State
policy requiring that “zero-carbon” resources supply 100% of all retail electricity sales to end-
user customers and all State agencies by December 31, 2045. If interpolated linearly between
60% renewable in 2030 and 100% zero-carbon in 2045, the interim 2035 target would be 73%
renewable. The reductions projected from the RPS total 186,115 MTCO2e in 2035.
RESULTS
The annual reductions from the above state and federal actions—Federal and California
Vehicle Efficiency Standards, California Energy Efficiency Standards, California Solar Policy,
Programs and 2019 Mandates, and Renewable Portfolio Standard—were combined. Table 3-
11 shows the total community forecast in 2035 considering federal and state actions, or
legislatively-adjusted BAU.

3.5 Modified Baseline: GHG Reductions from Additional
General Plan Policies and Actions
Methodology
This section describes General Plan policies and actions that reduce GHG emissions, quantifies
emissions reductions, and explains how these policies and actions will be implemented. These
reductions are from policies and actions in addition to BAU and legislatively-adjusted BAU
discussed in previous sections. The General Plan policies and actions are organized according
to the following categories:
• Bikeway System Improvements
• Pedestrian Improvements and Increased Connectivity
• Traffic Calming
• Parking Facilities and Policies
• Transportation Improvements
The California Air Pollution Control Officers Association’s (CAPCOA’s) Quantifying
Greenhouse Gas Mitigation Measures report was developed as a resource for local
governments to assess emissions reductions from GHG mitigation measures. This section uses
the methodology outlined in the CAPCOA report for each category to quantify emissions
reductions from the General Plan policies and actions.10 The reductions are applied to the
community forecast in the following section to get the “modified baseline” forecast.
10 While many of the policies and actions quantified in the report are project-level in nature, much of the supporting
literature is from studies on a citywide, countywide, or regional context. The methodology in this section is based on
these regional studies, which is therefore applicable to the General Plan policies and actions listed in this section.

2035 Reduction: 608 MTCO2e
Policy/Action Description
The Carlsbad Bikeway Master Plan, referenced in the General Plan, recommends the
enhancement of the existing bicycle network with the implementation of new Class I bike
paths, new Class II bike lanes, and new Class III bike routes, resulting in a 111.5 mile bikeway
system. The planned bikeways include the Coastal Rail Trail, a Class I bike path on Carlsbad
Boulevard at Ponto, two Class II bike lanes – one on Hillside Drive and another on Avenida
Encinas, and five Class III bike route projects in the northwest quadrant of the city.
In addition to Bikeway Master Plan recommendations, the Mobility Element identifies the
following new connections to improve connectivity in the area:
• A new Class I trail at the terminus of Cannon Road and extending eastward toward the
City of Oceanside
• A new Class I trail along the Marron Road alignment between El Camino Real and the
City of Oceanside
• A new crossing of the railroad tracks at Chestnut Avenue.
Also, CalTrans’ North Coast Corridor Public Works Plan includes, among other
improvements, a new North Coast Bike Trail and new bicycle/pedestrian connections across
Batiquitos and Agua Hedionda Lagoons.
Finally, the city can install new and enhanced bicycle facilities as opportunities arise in
conjunction with street maintenance and rehabilitation, and as part of “road diet” projects.
Quantification
An estimated 0.05 percent reduction in transportation GHG emissions is assumed to occur for
every two miles of bike lane per square mile in areas with density greater than 2,000 people
per square mile.11 Carlsbad currently has approximately 2,700 people per square mile, greater
than the threshold of 2,000 people per square mile.

1: INTRODUCTION
3-12
With the 111.5 miles of bicycle facilities, there would be approximately 2.85 miles of bikeways
per square mile, which corresponds to a 0.07 percent reduction in VMT emissions, or about
608 MTCO2e in 2035.
Implementation
The bikeway system enhancements will occur incrementally (at approximately .6 miles/ year)
through the implementation of the General Plan and planned and opportunistic bikeway
improvements (e.g., in conjunction with street maintenance and rehabilitation, or as part of a
“road diet”). Improvements will be funded and/or installed as conditions on new private
development as well as through the city’s multi-year CIP and annual operating budget process.
Funding sources may include development impact fees, general funds, local, state, and federal
grants.

Policy/Action Description
Pedestrian Improvements
Carlsbad has adopted several programs and plans related to improving the walking
environment. The city’s Pedestrian Master Plan guides the future development and
enhancement of pedestrian facilities to ensure that walking becomes an integral mode of
transportation in Carlsbad. The Carlsbad Residential Traffic Management Program provides a
mechanism for community members to report issues relating to speeding and traffic volumes
on residential roadways, assisting the city in “calming” traffic in these areas to make them
more comfortable for pedestrian travel.
Physical barriers to pedestrian access include gaps in sidewalks, high-volume, high-speed
streets, a circuitous roadway system in several parts of the city, and regional infrastructure such
as freeways and railways that presents barriers to pedestrian mobility. There are four significant
concentrations of high pedestrian improvement needs across the City of Carlsbad, including
the following locations:
• The entire northwest quadrant, especially the Carlsbad Village area
• The southern coastal area along Carlsbad Boulevard, between Cannon Road and La
Costa Avenue
• Several locations along El Camino Real, near Camino Vida Roble, Aviara Parkway/Alga
Road and La Costa Avenue
CARLSBAD CLIMATE ACTION PLAN
3-13
• The southeastern portion of the city, stemming from the intersection of La Costa Avenue
and Rancho Santa Fe Road
A range of potential improvement projects exists throughout the city, as identified in the
pedestrian master plan, to enhance pedestrian mobility, local connectivity, usage, safety and
accessibility. These improvements include filling in gaps in sidewalk connectivity, upgrading
substandard sidewalks, creating new connections to pedestrian attracting designations (such as
access across the railroad track to the beach at Chestnut Avenue, for example), establishing
safe routes to school, enhancing crosswalks, installing pedestrian countdown signals,
improving signage, and providing ADA improvements.
Increased Connectivity
Increasing connectivity in the city is critical to achieving the Carlsbad Community Vision.
There are a number of improvements described in the General Plan that will enhance
connectivity for bicycles and pedestrians, as noted below:
• Cannon Road east of College Boulevard – Provide a bicycle/pedestrian facility that
would begin at the current eastern terminus of Cannon Road and continue eastward to
the city’s eastern boundary.
• Marron Road Connection – Provide a bicycle/pedestrian facility that would begin at the
current eastern terminus of Marron Road and extend eastward to the city’s eastern
boundary.
• Additional crossings of Interstate-5 and the railroad – Continue to look for opportunities
to add crossings of these two barriers and improve east-west connectivity to and from the
coast. Key connections will include a crossing at Chestnut Avenue (bicycle, pedestrian,
and vehicular) under the freeway and (bicycle and pedestrian) across the railroad, and a
Chinquapin Avenue connection (bicycle, pedestrian, and vehicular) over the freeway and
(bicycle and pedestrian) across the railroad. Additionally, Caltrans is designing a number
of new pedestrian and bicyclist connections along and across Interstate-5 and near the
lagoons as part of the Interstate-5 North Coast Corridor Public Works Plan. The city will
continue to coordinate with Caltrans on these improvements.
• Improved accessibility to the lagoons and to the coast are envisioned to improve
connectivity to those areas.
Quantification
Providing an improved pedestrian network and increasing connectivity encourages people to
walk more and results in people driving less, causing a reduction in VMT. An estimate of a 1
percent reduction in VMT from pedestrian improvements and connectivity was assumed,
which corresponds to a reduction of 615 MTCO2e in 2035.12

Implementation
Pedestrian improvements and increased connectivity will occur through implementation of the
Pedestrian Master Plan, the Residential Traffic Management Program, and the General Plan,
and through planned and opportunistic pedestrian improvements (e.g., in conjunction with
street maintenance and rehabilitation, or as part of a “road diet”). Improvements will be funded
and/or installed as conditions on new private development as well as through the city’s multi-
year CIP and annual operating budget process. Funding sources may include development
impact fees, general funds, local, state, and federal grants.
Traffic Calming
Traffic Calming General Plan Policies:
2-P.53; 3-P.16, 3.P-17
2035 Reduction: 969 MTCO2e
Policy/Action Description
The Carlsbad Residential Traffic Management Program provides a mechanism for community
members to report issues relating to speeding and traffic volumes on residential roadways,
assisting the City in “calming” traffic in these areas to make them more safe and comfortable
for pedestrian travel. Traffic calming devices include speed tables, speed bumps, roundabouts,
and other devices that encourage people to drive more slowly or to walk or bike instead of
using a vehicle, especially for short trips in and around residential neighborhoods. The
residential traffic management program is implemented by the Transportation Division and
funded through the annual budget appropriation process.
Quantification
CAPCOA’s “Quantifying Greenhouse Mitigation Measures” was used to quantify the effect of
traffic calming devices. A 0.25 percent reduction in VMT was assumed to occur from these
improvements, which corresponds to a reduction of 969 MTCO2e in 2035.
Implementation
The traffic calming improvements will occur through the implementation of the Residential
Traffic Management Program and the General Plan.

2035 Reduction: 6,618 MTCO2e
Policy/Action Description
Getting parking right is critical to ensuring the success of any urban area. Inadequate parking
is inconvenient and frustrating for businesses and residents. Too much parking underutilizes
valuable land, results in lower density development, discourages use of other forms of
transportation (such as public transit), spreads out land uses, and creates gaps in store fronts;
CARLSBAD CLIMATE ACTION PLAN
3-15
thereby practically requiring the use of the automobile. Additionally, too much parking also
requires more driveways for accessibility, introducing conflicts between pedestrians and
vehicles. Overly high parking requirements—particularly in downtown areas or urban cores—
can impact the ability to renovate or repurpose older buildings and revitalize activity centers
that can be better served and connected by enhancing facilities and amenities for bicyclists and
pedestrians. Therefore, it is important to “right size” and manage parking such that there is
enough to support the needs generated by the use, but not so much that it wastes land and
impairs other ways of getting around.
The city’s Zoning Ordinance provides standards for parking facilities based on development
types within the city. To promote “right sizing” of parking facilities, the following techniques
are included as part of the General Plan Mobility Element:
• Shared Parking – continue to allow uses that have different parking demands at different
times of the day to share the same parking facilities. This is an effective way to minimize
pavement, allow denser land use, provide for more landscaping, and provide improved
walkability within a mixed use area. The best example of shared parking is an office
building and an apartment building as office’s peak parking demand occurs at 10:00 a.m.
and apartment’s peak parking demand occurs at 11:00 p.m.
• Collective Parking – allow uses in mixed use projects/areas to utilize up to 50 percent of
project site’s vacant on-street parking to count toward their parking supply requirements.
• Unbundled Parking – rather than provide free guaranteed parking, “unbundle” the
parking from the development and require residents and/or employees to pay for use of
a parking space.
• Park Once – a strategy in destination districts to enable visitors to “park once” and visit
a series of destinations. Park once strategies work well in areas like the Village and areas
that are well connected by pedestrian and bicycle facilities. The creation of centralized
parking areas supports this strategy.
• In Lieu Parking Fees – continue strategies in appropriate areas by which developers can
contribute fees toward the development of a common parking facility in lieu of providing
on-site parking. This works best in downtown or concentrated commercial areas, works
well to assist in paying for unified structured parking, and provides developers an
opportunity to increase density on their parcels.
• Parking Management Strategies –a business district or businesses manage high demand
parking locations and destinations through a number of different strategies including
demand pricing, time restrictions, valet parking, and other techniques.
• Public-Private Partnerships –the city, business owners, and developers collaborate to
provide both private and public parking opportunities. Instances where this works well
include parcels owned by the city, where a private entity comes in and develops,
manages, and enforces the parking in these public lots.
• Parking Locater Signs – electronic monitoring devices that identify the available parking
in a given facility and utilize changeable message signs to assist travelers in identifying
available parking locations. Please note that this may require modifications to the city’s
zoning ordinance to be implemented in some areas of the city.
1: INTRODUCTION
3-16
• Parking Wayfinding Signs – signs identifying where public parking is available, which
support the “park once” concept.
• Reduced Parking Standards – reduce parking standards in areas that are well served by
transit, provide shuttle accessibility to the COASTER station, provide parking cash out
programs (where employers pay employees to not park on site), or provide other
programs that will reduce parking demand.
• Biking Equals Business Program – businesses provide bicycle parking or corrals and
provide incentives to encourage their patrons and employees to ride rather than drive.
• Transit Equals Business Program – businesses provide their customers and employees
incentives to encourage them to use transit rather than drive.
• Bicycle Corrals in Lieu of Vehicle Parking – for certain businesses, reduce required
onsite parking for vehicles if they provide a bicycle corral that accommodates more
people.
Although there are additional parking strategies that are available and may become available
in the future, most of the strategies work best in smart growth/mixed use development areas
and will be necessary to accomplish the goals and visions identified in the General Plan and
the General Plan Mobility Element.
Quantification
According to CAPCOA’s Quantifying GHG Mitigation Measures, parking strategies have
estimated VMT reductions. Reduced parking standards and other policies reducing parking
availability have an estimated 5 to 12.5 percent VMT reduction, unbundled parking cost has a
2.6 to 13 percent VMT reduction, and parking management strategies have a 2.8 to 5.5 percent
VMT projection.13 Conservatively assuming the combined effect of these parking reduction
strategies would result in the lower end of the strategies results, and considering that the
strategies would be most applicable in future growth and infill areas, the cumulative reduction
from implementations would result in a 2 percent VMT reduction to give an estimated 6,618
MTCO2e reduction by 2035.
Implementation
The parking strategies will occur through the implementation of the Zoning Ordinance and the
General Plan. The city’s Planning Division is primarily responsible for developing new
ordinances and updating existing ones. Parking policy and ordinance changes would be carried
out under the Planning division’s annual budget authority.

Policy/Action Description
Transit in Carlsbad includes bus service, ADA paratransit service, and the COASTER
commuter rail; indirectly, transit service is also provided by the Sprinter light rail system,
Amtrak rail service, and Metrolink commuter rail. Future transit service in the city will
primarily be coordinated by the North County Transit District (NCTD). In addition, there are
several planned transit improvements for Carlsbad that are part of San Diego Association of
Governments (SANDAG) regional planning efforts. These are reflected in the General Plan
Mobility Element:
• Coastal rail improvements are proposed for the tracks serving the COASTER and
Surfliner trains in San Diego County along the Los Angeles to San Diego Rail Corridor.
These proposed improvements include double tracking, bridge replacements, and station
improvements. Improvements to the COASTER service (2020 and 2030) are also
proposed and would increase service and reduce headways.
• Route 471 (2020) is a proposed rapid bus providing frequent service between Carlsbad
and San Marcos via Palomar Airport Road. This route will operate with 10 minute
headways during peak and off-peak hours. In the city, this rapid bus route is envisioned
to be supported by signal priority at intersections.
• AMTRAK will add service to Carlsbad.
• As previously described, the above future transit improvements will continue to advance
the backbone transit infrastructure. However, one key component to improving transit
use is improving the “first mile/last mile” access and experience for transit users. This
typically includes end of trip facilities (bike racks, showers, changing rooms, etc.) and
better connectivity from the transit stop to the ultimate destination via bicycle facilities,
pedestrian facilities, local transit circulators, etc.
• Carlsbad’s future transit effectiveness will depend on major employers assisting with
providing some of these “first mile/last mile” facilities through transportation demand
management (TDM) measures. TDM is envisioned to include shuttle circulators to
major employers and destinations, showers and changing rooms at those locations, and
a host of other typical TDM techniques that would support transit usage and the
connection to the ultimate destination. This Mobility Element also supports TDM
through potential incentives (such as reduced parking standards for TDM
implementation) to further support transit access to these destinations.
• The final component to improving transit use in the city is working with NCTD to
improve the transit experience, particularly along the bus routes. This includes
improving bus stops in the city to ensure that they are well lit, have seating, and are
covered to protect users from inclement weather.
As part of the FY 2014-2015 capital improvement program, the city initiated work on a Coastal
Mobility Readiness Plan. This plan will complement current and planned bicycle and
pedestrian improvements by recommending policy and infrastructure investments that will:
improve accessibility to transit and para-transit services; fill in transportation gaps (“first mile-
1: INTRODUCTION
3-18
last mile” solutions); support and encourage expanded use of low-emission and zero emission
vehicles; provide viable alternatives to private, single-occupant vehicle use (such as through
car-sharing, bike-sharing, and local shuttles); and recommend other transportation/parking
demand management strategies. The plan will emphasize efficiently connecting residents and
visitors among the city’s various coastal activity centers, beaches, the state campground, and
to and from major hotels and resorts, the Village, major shopping centers, and other significant
visitor-serving activity centers. The plan will identify effective, proven tools, and seek out
promising and emerging technologies. The plan will also identify potential funding partners
such as NCTD (e.g. Cooperative Agreements in accordance with NCTD Board Policy 22),
private funding and/or public grants. The plan is expected to be completed at the end of 2015,
with implementation beginning in 2016.
The city has also implemented a state-of-the-practice traffic signal management (TSM) system.
This system integrates traffic signals in the city to a single access point, allowing city staff to
monitor and update signal timings to improve safety and mobility for all users in the city. The
Mobility Element supports further implementation of this program and use of other
technologies that become available, which have the ability to improve mobility for all users of
the city’s transportation system.
Quantification
Transportation system improvements can result in VMT reductions. According to CAPCOA’s
Quantifying Greenhouse Gas Mitigation Measures, transit system improvements can result in
the following reductions: 0.02 to 3.2 percent VMT reduction from a bus rapid transit system,
0.1 to 8.2 percent VMT reduction from expanding the transit network, 0.02 to 2.5 percent VMT
reduction from increasing transit service frequency and speed, and 0.5 to 24.6 percent VMT
reduction from increasing transit accessibility. Reductions from TSM were estimated using
Cambridge Systematics’ Moving Cooler report as a 0.01 percent VMT reduction.
Conservatively assuming the combined effect of these strategies, summing the low end of the
VMT reduction ranges gives a 0.63 percent reduction in VMT emissions.
Implementation
Transit improvements will primarily be coordinated by NCTD and will also be implemented
by SANDAG regional planning and funding efforts. City-led improvements will be carried out
through the city’s multi-year CIP and annual operating budget appropriation process.
Results
Table 3-12 shows the GHG reductions from each of the above General Plan policies and
actions. The largest reduction comes from parking facilities and policies, followed by
transportation improvements, traffic calming, pedestrian improvement and increased
connectivity, and bikeway system improvements. The reductions from these policies and
actions are incorporated into the community emissions forecast in the following section.

Table 3-13 shows the total community emissions with the reductions from the following
policies and actions:
• Federal and State actions
• Additional General Plan policies and actions
The BAU forecast for 2020 already meets the target reduction of four percent below baseline;
therefore, no analysis of the effects of federal and state policies and additional General Plan
policies was necessary. With the effect of all the GHG reductions considered in this chapter,
the total community forecast emissions are 455,556 MTCO2e in 2035. Table 3-13 shows that
Carlsbad met its target for 2020 without any additional measures. However, by 2035, there is
a GHG emissions “gap” of 116,817MTCO2e —approximately 20 percent of the total projected
community emissions.

Conclusion
The emissions targets are met in the year 2020, with BAU forecast emissions of 926,000
MTCO2e meeting the target by about 13,000 MTCO2e. There is an emissions “gap” in the year
2035 of about 116,817 MTCO2e between the forecast emissions of 588,817 MTCO2e and the
emissions target of 472,000 MTCO2e. Chapter 4 contains CAP GHG reduction measures to
close the gap between forecast emissions and emissions targets in the year 2035.

CAP GHG Reduction
Measures
The forecast emissions in Chapter 3 incorporate reductions from (1) state and federal actions,
(2) General Plan land use and roadways, and (3) additional General Plan policies and actions.
This chapter describes additional GHG reduction measures to close the emissions “gap”
between emissions targets and forecast emissions for 2035. These are:
• Commercial and industrial photovoltaic systems
• Single-family, multi-family and commercial efficiency retrofits
• Solar water heater/heat pump installation
• Efficient lighting standards
• Increased zero-emissions vehicle travel
• Transportation Demand Management (TDM)
• Citywide renewable projects
• Water delivery and conservation
The sections below describe the GHG reduction measures and explain how they will be
implemented. The GHG reductions from these measures were quantified using the Energy
Policy Initiatives Center (EPIC) mitigation calculator, a tool developed by the University of
San Diego for cities within San Diego County. The EPIC mitigation calculator includes a
“business as usual” (BAU) forecast for each measure estimating GHG reductions from trends
already underway that will occur without any additional city intervention, based on regional
San Diego Gas & Electric (SDG&E) forecasts. For example, under the BAU forecast for
residential photovoltaic (PV) systems, the EPIC mitigation calculator estimates that by the year
2035, energy produced by residential PV systems in the City of Carlsbad will be about 15.9
megawatts (MW), which will offset about 6,233 metric tons CO2e (MTCO2 e).
The GHG reduction measures describe goals, amount of reduction in 2035, and actions to meet
the target levels. The actions are categorized as short-term actions that will be implemented
within one to two years of CAP adoption; or mid-term actions that will be implemented within
4: CAP GHG REDUCTION MEASURES
4-2
two to five years of CAP adoption. Actions identified as short to long-term, or mid to long-
term are those actions that will begin in the short or mid-term, but take longer than five years
to fully implement. Ongoing actions are those that continue throughout the duration of CAP
implementation. The mixture of short-term, mid-term, long-term, and ongoing actions
presented for each measure are intended to meet the goals in a realistic timeframe and provide
an effective combination to reach the targets set forth. The “already-projected” amount is based
on the forecast BAU emissions reduction, followed by a target level to reach the goal of the
measure. The measures are then described in greater detail, as is the method of quantifying the
GHG emissions reduction, and the responsibility and implementation of the measure is
discussed. Each measure qualitatively describes costs and benefits, both to the city and the
private sector. Overall benefits of GHG emissions reductions include decreased costs through
energy efficiency, reduced risk to human health and welfare, and less global climate change.
The GHG reduction mitigation measures identified in this chapter are expected to achieve the
targeted emission reductions. However, the nature, location, timing, size and other
characteristics of future development projects may vary widely and additional project-level
mitigation measures may be helpful or necessary to assist individual projects to achieve the
targeted reductions. Accordingly, Appendix E to this Climate Action Plan provides a non-
exclusive list of mitigation measures to be considered by the City and project applicants during
project-level environmental review and adopted as needed to ensure that individual
development projects achieve the targeted emission reductions.
Note: CAP Amendment No. 1, approved May 5, 2020, recalculated the anticipated 2035 GHG reductions for all measures, based upon new state and federal policies and the interaction between the existing measures and new Measure P – Community Choice Energy. Four measures, Measures A, C, G and H, were eliminated for reasons described below. CAP Amendment No. 1 also updated the Actions calling for ordinance adoption; however, no other Actions were updated with this amendment. This update will occur with the comprehensive CAP update being processed in 2020-21.
4.1 Residential, Commercial and Industrial Photovoltaic
Systems
Measure A: Promote Installation of Residential Photovoltaic Systems – Deleted in CAP
Amendment No. 1
Goal: Promote installation of residential PV systems to produce
an additional 9.1 MW above already projected amounts, or the
equivalent of 2,682 more homes with PV systems, by 2035.
2035 Reduction: N/A
This Measure is no longer needed due to Section 150.1(c)14 of the 2019 California Energy Code,
mandating all new low-rise residential construction include solar photovoltaic energy generation systems.
CARLSBAD CLIMATE ACTION PLAN
4-3
Measure B: Promote Installation of Commercial and Industrial Photovoltaic Systems
Goal: Promote installation of commercial and industrial PV
systems to produce an additional 11.24 MW per year above
projected amounts by 2035.
2035 Reduction: 4,457 MTCO2e
Actions: (See also actions A1 and A2 above).
B-1: Implement and enforce Title 18, Chapter 18.30, Section 18.30.130 of the Carlsbad Municipal Code, mandating solar photovoltaic energy generation systems on new non-residential buildings.
(Ongoing)
B-2: Implement and enforce Title 18, Chapter 18.30, Section 18.30.130 of the Carlsbad Municipal Code, mandating solar photovoltaic energy generation systems on existing non-residential buildings
undergoing major renovations.(Ongoing)
Already-Projected Amount: The projected power generation from commercial and industrial
PV systems is 22.3 MW in the year 2035, which is about 30 percent of projected commercial
and industrial electricity use.
Target: The target is the PV production of 33 MW in the year 2035, which is the equivalent
amount of power production to supply about 45 percent of projected commercial and industrial
demand.
GHG Reduction Measure Description: Photovoltaic (PV) systems convert solar energy into
electricity. Measure B promotes the installation of PV systems on commercial buildings and
industrial facilities above the already-projected amount of 22.3 MW, by an additional 11.24
MW. Together with the already-projected amount of power generation, Measure B would reach
the target PV production of 33 MW in 2035.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure B.
Responsibility and Implementation: Property owners engaging in new construction and
major renovations will be responsible for providing PV systems. The City is responsible for
enforcing the ordinance, as well as encouraging the voluntary installation of non-residential
PV systems through the city website and other means.
Costs and Benefits:
Private: Private costs would result from the installation and maintenance of commercial and
industrial PV systems. Benefits would accrue from reduced energy bills and increased property
values.
City: City costs would occur from implementing and enforcing a nonresidential PV systems
ordinance.

This Measures will no longer result in significant GHG reductions due to the high renewable electricity
content associated with SDG&E’s RPS and the CEA CCE.
4.3 Single-family, Multi-family, Commercial, and City
Facility Efficiency Retrofits
Measure D: Encourage Single-Family Residential Energy Efficiency Retrofits
Goal: Encourage single-family residential efficiency retrofits with
the goal of a 50 percent energy reduction compared to baseline
in 30 percent of the total single-family homes citywide by 2035
(approximately 10,000 single-family homes out of a total of
35,000).
2035 Reduction: 7,986 MTCO2e
Actions:
D-1: Publicize available incentive and rebate programs, such as SDG&E’s Residential Energy Efficiency Program, on the city’s website and by other means. (Short-term)
D-2: Create a citywide “Energy Challenge,” similar to the Department of Energy’s Better Buildings Challenge, to promote cost-effective energy improvements, while having residents and building owners commit to reducing energy consumption. (Short-term)
D-3: Implement and enforce Title 18, Chapter 18.30, Section 18.30.190, mandating energy efficiency measures in existing residential buildings undergoing major renovations. (Ongoing)
Already-Projected Amount: There is no projection for retrofits that would occur without this
measure.
Target: The target is a 50 percent energy reduction in 30 percent of single-family homes
citywide by the year 2035.
GHG Reduction Measure Description: As single-family homes use a large portion of the
city’s total energy and older homes are substantially less efficient than newly constructed
homes, there is a large opportunity to reduce GHG emissions through the retrofitting of existing
homes. When a single-family homeowner seeks to make major improvements, the owner
would be required to meet low-cost energy efficiency measures—such as changing light bulbs
and switches, insulating exposed hot water piping, sealing air ducts, improving insulation, or
installing a “cool roof.” Additional voluntary energy efficiency measures could include
providing weather stripping, promoting natural lighting and ventilation, and using “smart”
thermostats to regulate energy use for heating and cooling.

Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure D.
Responsibility and Implementation: Homeowners would implement this measure. SDG&E
offers a Residential Energy Efficiency Program, which offers residential customers rebates to
improve the efficiency of appliances, such as water heaters, washers, refrigerators, air
conditioners, building insulating, and ceiling fans. The City will publicize this and related
programs on its website and by other means.
Costs and Benefits:
Private: Private costs would come from homeowners conducting energy audits and
implementing efficiency retrofits. The cost of these retrofits is frequently 1 percent or less of
the total renovation cost. Benefits would occur through reduced energy costs. Rebates are
available as described above.
City: City costs would come from promoting incentive programs and implementing and
enforcing a residential energy conservation ordinance.
Measure E: Encourage Multi-Family Residential Efficiency Retrofits
Goal: Encourage multi-family residential efficiency retrofits with
the goal of a 50 percent energy reduction in 30 percent of the
projected amount of multi-family homes citywide by 2035
(approximately 5,000 out of a total of 17,000).
2035 Reduction: 3,993 MTCO2e
Actions:
Action D-1: Publicize available incentive and rebate programs, such as SDG&E’s Residential Energy Efficiency Program, on the city’s website and by other means. (Short-term)
Action D-2: Implement and enforce Title 18, Chapter 18.30, Section 18.30.190, mandating energy efficiency measures in existing residential buildings undergoing major renovations. (Ongoing)
Already-Projected Amount: There is no projection for retrofits that would occur without this
measure.
Target: The goal is a fifty percent energy reduction in thirty percent of the projected amount
of multi-family homes citywide by the year 2035.
GHG Reduction Measure Description: Multi-family residential retrofits provide an
opportunity to reduce building energy use. Multi-family residential retrofits are similar to the
single-family retrofits described in Measure D. Other examples of potential multi-family
residential energy efficiency improvements include replacing incandescent and halogen lamps
with LED or CFL lamps, installing energy-efficient windows and efficient appliances, and
using “smart” thermostats to regulate energy use for heating and cooling.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure E.

customers rebates to improve the efficiency of appliances, such as water heaters, washers,
refrigerators, air conditioners, building insulating, and ceiling fans. The City will publicize this
and related programs on its website and by other means.
Costs and Benefits:
Private: Private costs would come from multi-family residential unit owners conducting
energy audits and implementing efficiency retrofits. Benefits would occur through reduced
energy costs. Rebates are available as described above.
City: City costs would come from promoting incentive programs and implementing and
enforcing a residential energy conservation ordinance.
Measure F: Encourage Commercial and City Facility Efficiency Retrofits
Goal: Encourage commercial and city facility efficiency retrofits
with the goal equivalent to a 40 percent energy reduction in 30
percent of commercial square footage citywide and in city
facilities by 2035.
2035 Reduction: 7,579 MTCO2e
Actions:
F-1: Undertake a program of energy efficiency retrofits for city-owned buildings, with the goal of 40 percent reduction in energy use, beginning with retrofits that would result in the most substantial energy savings. (Short-term)
F-2: Promote available incentive and rebate programs, such as SDG&E’s Energy Efficiency Business Rebates and Incentives Program, on the city’s website and by other means. (Short-term)
F-3: Implement and enforce Title 18, Chapter 18.21, Section 18.21.155, mandating energy efficiency measures in new non-residential buildings and existing non-residential buildings undergoing major
renovations. (Ongoing)
Already-Projected Amount: There is no projection for retrofits that would occur without this
measure.
Target: The target is equivalent to a 40 percent energy reduction in 30 percent of the projected
amount of commercial square footage and in city facilities.
GHG Reduction Measure Description: Relatively straightforward fixes to commercial and
city-owned buildings can significantly reduce spending on fuel and electricity for commercial
buildings. Examples of retrofits include installing efficient boilers and equipment, installation
of high-quality windows, efficient lighting, and other building energy improvements.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure F.
CARLSBAD CLIMATE ACTION PLAN
4-7
Responsibility and Implementation: Building owners would implement this measure for
commercial buildings.14 Funding is available through incentive and rebate programs, such as
SDG&E’s Energy Efficiency Business Rebates and Incentives Program. SANDAG prepared
an Energy Roadmap for the city, which included energy audits for most municipal facilities
and identified energy conservation measures the city can use to reduce energy use in city
municipal operations.15 Funding for city retrofits can be provided through the Energy
Efficiency Financing for Public Sector Projects program, described above in Measure C. As
well, the city will use its IRF to install energy efficiency retrofits as part of refurbishment of
existing city facilities.
Costs and Benefits:
Private: Private costs would come from building owners and business owners implementing
efficiency retrofits. Benefits would occur through reduced energy costs. Costs could be offset
through incentive and rebate programs.
City: City costs would come from retrofitting city facilities, providing resources to help guide
building owners to implement this measure, promoting available incentive and rebate
programs, and implementing and enforcing a commercial energy conservation ordinance.
4.4 Commercial and City Facility Commissioning
Measure G: Promote Commercial and City Facility Commissioning – Deleted in CAP Amendment
No. 1
Goal: Encourage commercial and city facility commissioning, or
improving existing and new building operations, with the goal
equivalent to a 40 percent energy reduction in 30 percent of
commercial square footage citywide and in city-owned buildings
by 2035.
2035 Reduction: N/A
This measure is now administered through the utility energy efficiency programs and accounted for in the
legislative business-as-usual projection for state policy and programs
14 AB 802 requires an owner of a nonresidential building 50,000 square feet or larger to benchmark the building’s energy use data and annually disclose the energy use to the state.

4.5 Green Building Code
Measure H: Implement Green Building Measures – Deleted in CAP Amendment No. 1
Goal: Implementation of a 5 percent improvement in energy
efficiency above the City of Carlsbad residential green building
code (based on CALGreen, the statewide green building code),
for new construction.
2035 Reduction: N/A
This Measure is no longer needed because new and future building codes are already more efficient than
the 2013 CALGreen code.
4.6 Efficient Lighting Standards
Measure I: Promote Replacement of Incandescent and Halogen Bulbs with LED or Other Energy
Efficient Lamps
Goal: Replace 50 percent of incandescent and halogen light
bulbs citywide with LED or similarly efficient lighting by 2035. 2035 Reduction: 22 MTCO2e
Actions:
I-1: Replace 50 percent of incandescent or halogen light bulbs in city facilities with LED or similarly
efficient lighting, or follow SANDAG Energy Roadmap recommendations for lighting in city facilities, whichever results in greater energy savings. (Short-term)
I-2: Promote the use of LED or other energy efficient lamps by publicizing rebate programs and information from SDG&E on the benefits of the use of LED or other energy efficient lighting on the
city’s webpage. (Short-term)
I-3: Evaluate the feasibility of adopting a minimum natural lighting and ventilation standard, developed
based on local conditions. Demonstrate natural lighting and ventilation features in future city facility upgrade or new construction. (Mid-term)
Already-Projected Amount: There are no projections for this measure.
Target: The target is to replace 50 percent of incandescent and halogen bulbs citywide with
LED bulbs or similarly efficient lighting by 2035.
GHG Reduction Measure Description: Replace inefficient incandescent and halogen light
bulbs with more efficient light bulbs to reduce the amount of energy needed to power the bulbs,
which will reduce the demand for electricity and thus the amount of GHG emissions created
by the electrical power generation. In November 2019, the California Energy Commission
(CEC) voted to ban the sale of inefficient light bulbs, effective January 2020. Inefficient light
bulbs are defined as any general service lamps with a efficacy of less than 45 lumens per watt.
SANDAG prepared an Energy Roadmap for the city, which included energy audits for most
municipal facilities. The city has, and will continue to, implement the lighting efficiency
replacements with the master refurbishment schedule.
I
CARLSBAD CLIMATE ACTION PLAN
4-9
Quantification of GHG Emissions Reductions: LED light bulbs reduce energy consumption
and therefore GHG emissions by 75 percent compared to incandescent lighting.16 Promotions
and rebates, outreach and education, and the recent CEC decision have all contributed to
lighting efficiency replacements in both the residential and commercial sectors. Therefore, the
GHG reductions from this measure are not significant.
Responsibility and Implementation: Carlsbad’s street lights were replaced in 2011 with
energy-saving induction units, leading to a reduction of approximately 1,240 MTCO2e per year
(already taken into account). The City has been and will continue to replace light bulbs within
City facilities with LED or similarly efficient lighting. For residential and commercial
customers, SDG&E currently does not offer rebates for the purchase of LED or similarly
efficient lighting, but the City will promote rebates as they come available on its website and
by other means. The City will also provide information on the benefits of the use of LED and
efficient lighting from SDG&E and other sources.
Costs and Benefits:
Private: Private costs would be from purchasing LED light bulbs for new construction, and
replacing existing light bulbs over time. Benefits would be from reduced energy costs and
reduced cost to replace light bulbs (as LED lights last substantially longer).
City: City costs would come from replacing existing inefficient lighting in City facilities with
more efficient light bulbs over time, providing information to homeowners and business
owners to encourage a switch to LED or other efficient lamps, and evaluating the feasibility of
a natural lighting and ventilation ordinance.
4.7 Solar Water Heater/Heat Pump Installation
Measure J: New Construction Residential and Commercial Solar Water Heater Installation
Goal: Install solar water heaters or heat pumps on all new
residential and commercial construction. Retrofit up to 30
percent of existing homes and commercial buildings to include
solar water heaters or heat pumps.
2035 Reduction: 2,813 MTCO2e
Actions:
J-1: Promote the installation of solar water heaters and heat pumps by publicizing incentive, rebate and financing programs, such as PACE programs and the California Solar Initiative for renovations of existing buildings by posting this information on the city’s website and by other means. (Short-term)
J-2: Implement and enforce Title 18, Chapter 18.30, Sections 18.30.150 and 18.30.170, mandating alternative water heating requirements in new residential and non-residential buildings. (Ongoing)

4: CAP GHG REDUCTION MEASURES
4-10
Already-Projected Amount: There are no solar water heaters/heat pumps projected to be
installed.
Target: The target is to install solar water heaters or heat pumps on all new residential and
commercial construction, and retrofit up to 30 percent of existing homes and commercial
buildings to include solar water heaters or heat pumps.
GHG Reduction Measure Description: Solar water heaters use water heated by the sun to
provide domestic and commercial hot water. Solar water heaters reduce the demand for energy
used to heat water. A solar water heater can contribute 30 to 80 percent of the energy needed
for residential water heating.17 Heat pumps are devices that use a small amount of energy to
move heat from one location to another.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure J.
Responsibility and Implementation: The City of Carlsbad currently participates in three
Property Assessed Clean Energy (PACE) programs: CaliforniaFIRST, Ygrene, and California
HERO. PACE programs provide financing to eligible property owners for sustainable energy
projects, including the installation of solar water heaters and heat pumps to improve residential
energy efficiency. Installation of solar water heaters on all new residential and commercial
water heaters could occur through city ordinance. Retrofit of existing homes could occur
through a combination of additional encouragement and incentives.
Costs and Benefits:
Private: Private costs would occur through the installation of residential and commercial solar
water heaters, which would be passed onto building owners. Benefits would occur through
reduced water heating costs.
City: City costs would occur from implementing and enforcing an ordinance requiring new
homes and commercial buildings to install solar water heaters or heat pumps.

4.8 Transportation Demand Management
Measure K: Promote Transportation Demand Management Strategies
Goal: Promote Transportation Demand Management Strategies
with a goal of achieving a 10 percent increase in alternative
mode use by workers in Carlsbad, for a total of 32 percent
alternative mode use.
2035 Reduction: 6,325 MTCO2e
Actions:
K-1: Implement the citywide transportation demand management (TDM) plan and strategies. (Ongoing)
K-2: Implement and enforce Title 18, Chapter 18.51, mandating TDM improvements and strategies for
non-residential development. (Ongoing)
Already-Projected Amount: There are no projections for this measure. As of 2012,
alternative (non-single occupancy vehicle use—such as working at home, carpooling, transit,
walking and biking) mode use by Carlsbad workers is 22 percent.18 Of these alternative uses,
most workers work at home (44 percent) and carpool (36 percent), followed by public transit
(10 percent), other means (including biking, 6 percent), and walking (5 percent).
Target: The Carlsbad General Plan promotes the use of Transportation Demand Management
(TDM), but does not specify a target goal. This measure specifies a goal of achieving an
additional 10 percent use of alternative modes, for an overall 32 percent alternative mode use
by workers employed in Carlsbad. This is projected to be achieved through 40 percent
alternative mode use by workers in new nonresidential buildings, and 30 percent alternative
mode use by workers in existing (as of 2013) nonresidential buildings.
GHG Reduction Measure Description: Chapter 3 quantifies emissions reductions from the
Carlsbad General Plan due to bikeway system improvements, pedestrian improvements, traffic
calming, parking facilities and policies, and transportation improvements. This measure is
distinct from these reductions because it focuses on TDM, or the application of strategies and
policies to reduce travel demand, or redistribute it in time and space. This measure reduces
VMT by shifting single occupancy vehicle use to alternative modes, reducing the average
commute length, promoting an alternate work schedule, and promoting telecommuting.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure K.
Responsibility and Implementation: The City of Carlsbad will implement a TDM plan
describing strategies to reduce travel demand. The city will also implement an ordinance
applying to nonresidential developments meeting a specified minimum trip generation

threshold, providing connections to public transportation whenever possible. The city will
facilitate a coordinated effort between local businesses and NCTD to develop a route expansion
and ridership plan wherever feasible. SANDAG’s iCommute program assists commuters by
providing free carpool and ridematching services, a subsidized vanpool program, the
Guaranteed Ride Home program, SchoolPool carpooling programs for parents, and
information about teleworking, all of which can support the city’s TDM goals.
Costs and Benefits:
Private: Private costs could include need for a TDM coordinator for private businesses,
providing on-site facilities (showers, lockers), and shuttle programs. Benefits would accrue
from reduced spending on gasoline, and reduced traffic from less employee commute.
City: City costs would result implementing and enforcing a TDM plan and ordinance.
Implementation costs would include conducting an outreach and education campaign to
promote the benefits of TDM.

4.9 Increased Zero-Emissions Vehicle (ZEV) Travel
Measure L: Promote an Increase in the Amount of Zero-Emissions Vehicle Travel
Goal: Promote an increase in the amount of ZEV19 miles
traveled from a projected 4.5 percent to 25 percent of total
vehicle miles traveled by 2035.
2035 Reduction: 49,912 MTCO2e
Actions:
L-1: Working with industry partners, construct a “PV to EV” pilot project to install a PV charging station at
a city facility (such as the Faraday Center), to charge city ZEVs. The purpose of the pilot project would be to evaluate the feasibility of incorporating more ZEV into the city’s fleet. (Short-term)
L-2: Prepare a community-wide charging station siting plan, which evaluates site visibility and exposure, EV driving ranges, high volume destinations, locations with high ownership or interest in EVs, and cost of construction. (Short-term)
L-3: Construct ZEV charging stations based on the community-wide charging station siting plan described in L-2 above. The ZEV charging stations will be funded by grant funds when available,
and the city will post signage directing ZEVs to charging stations. (Mid-term)
L-4: Offer dedicated ZEV parking, and provide charging stations adjacent to ZEV parking as identified in
the community-wide charging station siting plan. (Mid-term)
L-5: Adopt requirements for ZEV parking for new developments. (Short-term)
L-6: Implement and enforce Title 18, Chapter 18.21, Sections 18.21.140 and 18.21.150, mandating
electric vehicle charging infrastructure in new residential and non-residential building and existing residential and non-residential buildings undergoing major renovations. (Ongoing)
L-7: Update the city’s Fleet Management Program to include a low and zero-emissions vehicle
replacement/purchasing policy. Increase the proportion of fleet low and zero–emissions vehicle miles traveled to 25 percent of all city-related VMT by 2035. (Short-term)
Already-Projected Amount: According to the EPIC mitigation calculator, 4.5 percent of the
vehicle miles traveled in 2035 are projected to be from ZEVs.
Target: The target is to increase the proportion of vehicle miles traveled from 4.5 percent to
25 percent by the year 2035.
GHG Reduction Measure Description: Driving ZEVs reduces carbon emissions by
eliminating direct tailpipe emissions of carbon dioxide and other GHGs. The production of
electricity used to power electric vehicles generates GHGs; however, SDG&E electricity
generates much less GHGs than the direct combustion of fossil fuels. Furthermore, electric
vehicles can be charged at home or the workplace using energy produced by PV panels,
eliminating GHG emissions completely, at least for the months when PV panels produce the
full amount of electricity needed for operations. The ability to provide entirely emissions-free
19 Zero-Emissions Vehicle (ZEV) is a vehicle that emits no tailpipe pollutants from the onboard source of power. ZEVs
include electric vehicles, fuel cell vehicles, and plug-in hybrids, when in electric mode.
4: CAP GHG REDUCTION MEASURES
4-14
transportation through the use of PV panels to charge ZEVs should be capitalized on whenever
possible.
Quantification of GHG Emissions Reductions: The EPIC mitigation calculator was used to
quantify emission reductions for Measure L.
Responsibility and Implementation: The city will promote an increase in the amount of
electric vehicle travel by constructing ZEV charging stations using the community-wide station
siting plan. Grant funding for the construction of the ZEV charging stations can come from the
California Energy Commission’s Electric Vehicle Charging Infrastructure grant, or other
similar grant programs. The city would be responsible for operating (including electricity
provision, for stations not using PV panels) and maintaining charging stations.
The city is also promoting the use of ZEVs by requiring dedicated ZEV parking and charging
infrastructure for new development and major renovations. Through its Fleet Vehicle
Replacement Fund, the City of Carlsbad is increasing the city fleet mix of ZEVs, hybrids, and
other low- or zero-emissions vehicles to increase low and zero–emissions vehicle miles
traveled to 25 percent by 2035.
Costs and Benefits:
Private: The private cost would be the purchase of an electric vehicle and the cost of electricity
to power the electric vehicle, for community members who elect to purchase an electric vehicle.
Costs may also occur from installing EV chargers or pre-wiring into new residential
construction or major renovations. Benefits would accrue from reduced spending on gasoline.
City: City costs would be from planning for, constructing, operating (including providing
electricity, for stations not using PV panels) and maintaining ZEV charging stations, which
may be offset by potential user fees or grants from the California Energy Commission, or other
similar agencies. City costs would also be from implementing ordinances to require the
installation of ZEV chargers.. City costs may also occur from fleet purchases of ZEV vehicles.
Benefits would accrue from reduced spending on gasoline.

4.10 Citywide Renewable Projects
Measure M: Develop More Citywide Renewable Energy Projects
Goal: Produce the equivalent amount of energy to power 2,000
homes (roughly equivalent to a 5 percent reduction) by 2035
from renewable energy projects.
2035 Reduction: 2,774 MTCO2e
Actions:
M-1: Conduct a feasibility study to evaluate citywide renewable energy projects and prioritize accordingly. (Short-term)
M-2: Incorporate renewable energy measures such as PV system installation on city buildings and parking lots, or microturbine installation on city facilities, with the goal of producing approximately
12,000 megawatt-hours per year. (Mid to Long-term)
M-3: Pursue available funding sources for the construction of renewable energy projects by the city,
such as Energy Efficiency Financing for Public Sector Projects and SGIP. (Mid to Long-term)
Already-Projected Amount: There is no projected amount for this measure.
Target: The target is the production of 12,341 megawatt-hours per year, approximately the
energy required to power 2,000 homes.
GHG Reduction Measure Description: The City of Carlsbad has a number of renewable
energy projects in various stages of planning and development. The Maerkle Reservoir
Hydropower Project, which has been permitted by the Federal Energy Regulatory Commission
(FERC), is estimated to produce about 833 MWh per year. In 2014, Alga Norte Community
Park was outfitted with a PV system in the parking area, which will generate some 360 MWh
of electricity per year. Other planned projects include a second pressure-reducing hydroelectric
generator, similar to the Maerkle Reservoir Hydropower Project, and a potential large PV
system at the Maerkle Reservoir property.
Quantification of GHG Emissions Reduction: The production of 12,341 megawatt-hours per
year corresponds to a reduction of 2,774 MTCO2e.
Responsibility and Implementation: The City of Carlsbad would be responsible for
conducting a feasibility study, determining suitable renewable technologies, siting renewable
projects, and constructing and maintaining the renewable energy projects. Funding sources
include the Energy Efficiency Financing for Public Sector Projects, which includes renewable
energies such as PV systems and other distributed generation technologies, as well as the Self-
Generation Incentive Program (SGIP). As well, the city will use IRF to install renewable
energy systems as part of refurbishment of existing city facilities, where it is feasible to do so.
4: CAP GHG REDUCTION MEASURES
4-16
Costs and Benefits:
Private: There are no direct private costs from this measure.
City: City costs are planning (including a feasibility study), constructing and maintaining the
renewable facilities, some of which may be offset through the funding sources described above.
Benefits accrue from electricity savings to City through net energy metering.
4.11 Water Utilities System Improvements
Measure N: Reduce GHG Intensity of Water Utilities Supply Conveyance, Treatment, and
Distribution 20
Goal: Reduce the intensity of GHG emissions from water utilities
(including water supply, wastewater, and recycled water)
conveyance, treatment, and distribution by 8 percent by 2035.
2035 Reduction: 713 MTCO2e
Action:
N-1: Improve water utilities (including water supply, wastewater, and recycled water) conveyance, treatment and distribution, and other system improvements. (Mid to Long-term)
Already-Projected Amount: The goal of an 8 percent reduction by 2035 is the default value
in the EPIC mitigation calculator.
Target: The target is to achieve the already-projected amount.
GHG Reduction Measure Description: This measure estimates emissions reductions from
changes in the efficiency of water utilities (including water supply, wastewater, and recycled
water) conveyance, treatment, and distribution facilities within the City of Carlsbad.21 This
combines improvements in overall system efficiency, the reduction in GHG intensity of
electricity used to move water, wastewater, and recycled water, and replacing potable water
needs with expanded recycled water supply. Carlsbad’s Sewer Master Plan, for example, calls
for eliminating several sewer lift stations and replacing them with gravity pipelines, which
would reduce energy usage.22 The Encina Water Pollution Control Facility exemplifies GHG
reductions from water treatment; the facility currently is able to satisfy 60 percent of its energy
needs through methane capture and cogeneration and has a long-term goal of energy
independence from purchased energy. The 2012 Carlsbad Municipal Water District Recycled
20 For purposes of this measure, water utilities include potable water treatment and conveyance, sewer conveyance, and
recycled water treatment and conveyance systems.
21 Note: The GHG reductions from water conservation measures detailed in the 2010 Carlsbad Municipal Water District
Urban Water Management Plan (UWMP) have already been considered in the GHG forecasts. Further GHG reductions may be possible through greater conservation efforts than those outlined in the UWMP, including Ordinance No. 44
(2009); however, these have not been quantified in this CAP.
22 The City is replacing three sewer lift stations, which use a combined total of approximately 6,200 kWh of electricity
per year with gravity pipelines, in addition to other planned rehabilitation upgrades included in the Sewer Master Plan.
CARLSBAD CLIMATE ACTION PLAN
4-17
Water Master Plan estimates that, by 2030, recycled water demand could double from 4,100
acre-feet/year to about 9,100 acre-feet/year. Expanding the recycled water system would
appreciably reduce the need for more expensive imported water needs in the future.
Quantification of GHG Emissions Reduction: The EPIC mitigation calculator was used to
quantify emission reductions for Measure N, which estimates wastewater emissions reductions
from methane capture, reductions from water treatment and distribution facilities, and changes
in the supply network, including greater use of recycled water.
Responsibility and Implementation: The City of Carlsbad would be responsible for making
the improvements to water supply conveyance, treatment, and distribution, which could occur
through improvements to the Carlsbad Municipal Water District’s system.
Costs and Benefits:
Private: There would be no private costs for this measure.
City: Costs to the City of Carlsbad are from implementing the improvements to the water
utilities system. Benefits occur by reducing energy costs and having newer water delivery
infrastructure.
Measure O: Encourage the Installation of Greywater and Rainwater Collection Systems
Goal: Encourage the installation of greywater and rainwater
collection systems with a goal of 15 percent of homes by 2035.
2035 Reduction: 137 MTCO2e
Actions:
O-1: Host workshops on greywater and rainwater collection systems through the Carlsbad Municipal
Water District, or partner with existing workshop providers, for homeowners interested in installing systems suitable for their property. (Mid-term)
O-2: Create a design reference manual, or provide links to an existing one, for the design of greywater and rainwater collection systems. (Mid-term)
O-3: Evaluate the feasibility of offering a rebate for residential greywater systems that require a permit to cover the cost of obtaining a permit. (Mid-term)
Already-Projected Amount: There is no projection for this measure.
Target: The target is for 15 percent of single-family homes to have greywater and rainwater
collection systems installed by 2035.
GHG Reduction Measure Description: Greywater is wastewater generated from hand
washing, laundry machines, and showers and baths that have not been contaminated by any
toilet discharge. Greywater can be recycled onsite for toilet flushing and subsurface (below
ground) landscape irrigation using a greywater system. The regulations for the design,
construction and use of greywater systems are in Chapter 16A of the California Plumbing
I
4: CAP GHG REDUCTION MEASURES
4-18
Code. Some small greywater systems that involve laundry machines or single fixtures only are
exempt from permits. More complicated greywater systems require building permits from the
City. Rainwater harvesting is the practice of collecting rainwater from hard surfaces, such as
roofs, and storing it in barrels or cisterns, which can be used for landscape irrigation. Measure
O is to promote the use of on-site greywater and rainwater collection systems for residences.
Quantification of GHG Emissions Reductions: Nationwide, about seven percent of U.S.
GHG emissions are from water and wastewater service provision to urban populations.23 For
this measure, it was assumed that seven percent of the citywide emissions are from water
provision and wastewater services.24 Therefore, about 32,000 MTCO2e of 2035 emissions are
from water provision and wastewater services.
If maximally pursued, the use of greywater and rainwater collection systems could reduce
water demands by 25 percent on a statewide scale.25 For this measure, it was assumed the 25
percent reduction in water demand would scale to individual houses that implement greywater
and rainwater collection systems. A goal of 15 percent of homes with greywater and rainwater
harvesting systems was chosen. A 25 percent reduction of water use in 15 percent of homes
corresponds to a GHG reduction of about 137 MTCO2e.
Responsibility and Implementation: Homeowners would be responsible for the installation
of greywater and rainwater collection systems. The City of Carlsbad will, through the Carlsbad
Municipal Water District, host greywater and rainwater harvesting workshops, or partner with
existing workshop providers. The City will also reference or develop a greywater and rainwater
collection system design manual and consider offering a rebate for residential greywater
systems that require a permit to cover the cost of obtaining a permit.
Costs and Benefits:
Private: Costs to homeowners would be from constructing and maintaining greywater and
rainwater collection systems. Benefits would accrue over time through water savings.
City: Costs to the City of Carlsbad are from hosting workshops and developing or reviewing
greywater and rainwater collection manuals to adopt.

4.13 Clean Electricity
Measure P: Increase the Proportion of Clean Electricity in Community Energy Consumption
Goal: Achieve 100% renewable electricity by 2030 for 95% of
the residential bundled load and 85% commercial + industrial
bundled load.
2035 Reduction: 56,207 MTCO2e
Action:
P-1: Continue participation in the Clean Energy Alliance Community Choice Energy program (Ongoing).
P-2 Explore the purchase of renewable energy credits if Community Choice Energy program is not reaching 2035 goal.
Already-Projected Amount: There is no projection for this measure.
Target: The target is for 95 percent of the bundled residential load and 85 percent of the
bundled commercial plus industrial load to use 100% renewable electricity.
GHG Reduction Measure Description: California Assembly Bill 117 allows local
governments to form Community Choice Aggregations, commonly referred to as Community
Choice Energy (CCE) program. These programs offer an alternative electric power option to
customers with the area currently served by an investor-owned utility. CCEs allow local
jurisdictions to increase the proportion of renewable energy available to customers that, in turn,
lowers the GHG emissions from electricity consumption. Another means to lower electricity-
related GHG emissions is to purchase renewable energy credits as an offset to the consumption
of electricity from non-renewable generation sources.
Quantification of GHG Emissions Reductions: The GHG emissions reductions anticipated
with this measure are derived from the Community Choice Energy Technical Feasibility Study
(prepared by EES Consulting, Inc. and dated March 28, 2019), which was prepared for the
cities of Carlsbad, Del Mar, Encinitas and Oceanside. The study evaluates three renewable
energy portfolio scenarios: an SDG&E equivalent; 100% renewable by 2030; and, 100%
renewable upon inception. The GHG emissions reductions associated with this measure are
beyond the reductions assumed by the state mandated renewable portfolio standard.
Responsibility and Implementation: The Clean Energy Alliance Joint Powers Authority and
its staff are responsible for implementing the Community Choice Energy program. Electricity
customers can choose the proportion of renewable energy they consume (50% or 100%). City
staff will monitor the program participation rates and renewable proportions, amount of
renewable energy procured, and the resulting GHG emissions reductions to determine the need
for purchasing renewable energy credits to meet the 2035 reduction target.
4: CAP GHG REDUCTION MEASURES
4-20
Costs and Benefits:
Private: Costs to electricity customers will be a function of the Clean Energy Alliance rate
structure and the proportion of renewable energy purchased through the program.
City: Costs to the City of Carlsbad are from staff and financial contributions to the Clean
Energy Alliance Joint Powers Authority and, if needed, the purchase of renewable energy
credits.
4.14 Combined Effect of CAP GHG Reduction Measures and
Forecast with CAP
Table 4-1 shows a summary of the CAP GHG reduction measures. While the individual
measures may be implemented over different timescales, for the purposes of calculating their
impact in this section, it was assumed that the effect of all measures would begin in the mid-
term time frame and increase linearly to reach the full reduction potential in the year 2035.
As a whole, the CAP GHG reduction measures were designed to enable Carlsbad to achieve
its GHG reduction target in the year 2035. The combined GHG reductions from these measures
is 142,918 MTCO2e in 2035, which covers the emissions “gap” identified in Chapter 3. Table
4-2 adds the effect of the CAP GHG reduction measures to the community forecast, and
compares the resulting forecast with CAP GHG reduction measures to emission targets. As
proposed, this CAP meets the emissions targets for both 2020 and 2035. Figure 4-1 shows the
forecast with CAP reduction measures compared to the emissions targets to demonstrate that
both 2020 and 2035 targets will be met with the implementation of this CAP.
For this CAP to successfully be implemented, the City of Carlsbad must play a prominent role
in implementing the CAP GHG reduction measures. In addition to responsibility and
implementation covered for each measure in this chapter, the following chapter discusses how
the CAP will be revised and updated in the future to ensure that the targets are met.

Implementation, Monitoring
and Reporting
Chapters 3 and 4 identify a comprehensive set of goals and specific, enforceable measures and
actions that the city will take in order to meet its GHG emissions targets. Implementation and
monitoring are key to ensuring that the city is successful in reaching those targets. The city will
use an adaptive management approach to CAP implementation. Adjustments to management
actions will be made as needed to support continuous improvement based on measured results,
monitoring effectiveness, new technology, or in response to deficiencies in program
assessment results. This chapter describes how the City of Carlsbad will implement the CAP
and monitor and report on its effectiveness, consistent with State CEQA Guidelines Sections
15183.5(b)(1)(D) and (E).
For discretionary projects seeking to use CEQA streamlining provisions, in an environmental
document the city shall refer to the required measures in this CAP as mandatory conditions of
approval or as mitigation. This will enable projects to benefit from CEQA streamlining
provisions, while ensuring that the city can achieve the reduction targets outlined in this plan.
5.1 Implementation
Table 5-1 lists all of the measures and actions identified in Chapters 3 and 4 along with the
following information:
Responsible Department: The city department(s) that will be primarily responsible for
implementing, monitoring, and reporting on the progress for each measure.
Annual GHG Reduction Goal: The estimated annual emission reductions anticipated by the
2035 target year.
Performance Target: The expected quantified outcome of the GHG reduction measure.
Progress Indicators: The types of data that will be collected to measure progress toward the
performance target and correlate to GHG emissions reductions. Progress indicators will be
5: IMPLEMENTATION, MONITORING AND REPORTING
5-2
confirmed as part of the implementation of each measure. If a recommended progress indicator
is found to be infeasible to collect or track, an alternative indicator will be identified.
Unit of Measure: Input units used to calculate GHG emissions reductions (MTCO2e),
whereby:
Gallons of water = water consumption
kWh/MWh = electricity consumption in kilowatt-hours or megawatt-hours
MTCO2e = metric tons of CO2 equivalent emissions
Therm = natural gas consumption in therms
VMT = vehicle miles traveled
Implementation Timeframe: The schedule by which each action is to be implemented,
beginning from the year the CAP is adopted, as follows:
Short-term – one to two years
Mid-term – two to five years
Short to Long-term, or Mid-to Long-term – actions that will begin in the short or mid-
term, but take longer than five years to fully implement.
Ongoing - continue for the duration of CAP implementation

5.2 Monitoring and Reporting
This CAP serves as a toolkit for the City of Carlsbad to reduce community-wide GHG
emissions and meet emissions targets. Climate action planning, however, is an iterative and
adaptive management process: it requires administration, public outreach, monitoring progress
and measuring results, periodically revisiting assumptions and adjusting provisions when
necessary. Through regular monitoring and measuring the performance of CAP activities, the
city will learn what is working and what is not. This will enable the city to make timely
adjustments to existing measures, replace ineffective actions, and/or add new measures as
changes in technology, federal and state programs, or other circumstances warrant.
Figure 5-1 shows the steps in the process of climate action planning.
Figure 5-1: Process of Climate Action Planning
To continue
the process of climate action
planning, the City of
Carlsbad will follow these
steps:
• Administration
• Education and
Outreach
• Monitoring and
Reporting
• Updating GHG
inventory and the CAP
• Update Project Review
Checklist
Administration
Following adoption of this CAP, the city will designate a CAP administrator and form an
interdisciplinary CAP implementation team from within the city organization. The
administrator, in conjunction with the implementation team, will be responsible for initial
program start-up activities and for overseeing implementation, monitoring and reporting of all
actions described in the CAP. The composition of the implementation team may vary from
time to time as needed, but it is expected that core members will include staff from Public
Inventory GHG Emissions
Set Reduction Targets
Update GHG Inventory
Develop (Update) Climate Action Plan
Implement Measures
Measure Effectiveness Report Progress
5: IMPLEMENTATION, MONITORING AND REPORTING
5-14
Works, Community and Economic Development, Finance, and Communications departments.
As some of the monitoring and reporting activities will require coordination with other
agencies, the implementation team will need to foster effective partnerships accordingly.
Operating resources for administering the CAP will be provided through the city’s annual
budget process. To maximize efficiency and maintain costs, the city will integrate CAP
implementation activities into existing workloads and programs whenever possible. Potential
private and public funding resources for individual GHG reduction measures are identified in
the measure descriptions in Chapter 4. However, since program incentives and funding sources
change over time, the CAP administrator and Implementation Team will need to keep current
on available resources as GHG reduction measures are implemented.
Education and Outreach
A program of this scope and consequence will require substantial community support in order
to succeed. Key to garnering this support is to raise the level of community awareness through
education and outreach. Most of the individual GHG reduction measures in Chapter 4 include
a promotion and education component. Appendix A provides a listing of internet resources on
a variety of climate change-related topics. In addition to these features built into the CAP, the
city will utilize its website, social media, and other communications channels to provide
information about climate change science and anticipated impacts, and by providing residents
and businesses with information and resources to help them take action. The city’s website
already has a good deal of information related to energy and water efficiency programs, and
other environmental sustainability efforts. This Climate Action Plan is also available on the
city’s website. The city will build upon this base of resources by providing current information
and links to various local, state and federal incentive programs to reduce one’s carbon footprint,
and provide assistance to homeowners, businesses, and contractors seeking to make energy
efficiency improvements.
Monitoring and Reporting
The City of Carlsbad will annually monitor and report on CAP implementation activities. The
annual monitoring report will include implementation status of each action and progress
towards achieving the performance targets of the corresponding emissions reduction measure.
The annual monitoring report will also include information on the status of the federal and state
level emissions reductions measures identified in Chapter 3 of this CAP, as well as any new
efforts that may emerge in the reporting year. The annual report will be presented to the City
Council at a public meeting during which interested parties may comment on the report.
Updating GHG Inventory and the CAP
The city will update the community and government operations inventories for calendar year
2014 for inclusion in the first annual report, and then will update the inventories every three
years thereafter. For continuity, the inventory updates will tally emissions from the same
sectors analyzed in Chapter 2 of this CAP. If an updated inventory reveals that the plan is not
making adequate progress toward meeting the GHG target, or that new technologies and
programs emerge that warrant inclusion in the CAP, the city will adjust the CAP by modifying,
adding, and/or replacing measures as necessary. New opportunities for GHG reductions,
CARLSBAD CLIMATE ACTION PLAN
5-15
including new funding sources and the ability to link city reduction actions to the city’s Capital
Improvement Plan, Infrastructure Replacement and Fleet Vehicle Replacement schedules, and
other programs can also be incorporated into future updates of the CAP. Interim “milestone”
targets for years 2025 and 2030 as shown in Table 4-3 will be used to gauge whether the city
is making adequate progress toward meeting the 2035 target. Recommendations to adjust the
CAP may be presented to the City Council as part of the annual report or at any other time
throughout the year as necessary to ensure effective CAP implementation.
5.3 Project Review Thresholds and Checklist
Compliance with CAP
During the course of project review, city will evaluate whether a project is subject to provisions
of this CAP, using the screening criteria below. Once this is established, a project shall comply
with the CAP in one of two ways:
•Checklist Approach. The Project Review Checklist below provides direction about
measures to be incorporated in individual projects, which will be used during the normal
development review process. Project features that help a project meet the provisions of
the CAP shall then become part of project conditions of approval.
•Self-Developed Program Approach. Rather than use the standard checklist, project
proponents can develop their own program that would result in the same outcome as the
checklist. Appendix E provides a non-exclusive list of potential mitigation measures that
can be applied at the project level to reduce project-level greenhouse gas emissions.
Other measures not listed in the Appendix may be considered, provided that their
effectiveness in reducing greenhouse gas emissions can be demonstrated. The self-
developed program approach and selection of mitigation measures shall be subject to city
review and approval.
CEQA Streamlining
Project Screening Thresholds
The California Air Pollution Control Officers Association (CAPCOA) public various
screening thresholds to guide lead agencies in determining which projects require greenhouse
gas analysis and mitigation for significant impacts related to climate change. Utilizing this
guidance, the City has determined that new development projects emitting less than 900
MTCO2e annual GHG would not contribute considerably to cumulative climate
change impacts, and therefore do not need to demonstrate consistency with the CAP.
The city prepared a "Climate Action Plan Consistency Checklist” and “Guidance
to Demonstrating Consistency with the Climate Action Plan For Discretionary
Projects Subject to CEQA," which lists the types and sizes of projects that
correspond to the 900 MTCO2e screening threshold. The documents were revised to
reflect adoption of CAP ordinances. For proposed projects above the screening
threshold, project proponents shall complete the Checklist.
Appendix A
Climate Change
Informational Resources
Combating climate change requires education and personal action. This section contains
resources on climate change and its impacts, calculating individual carbon footprints, and
ways to reduce individual carbon footprints.
Education
The evidence is clear that climate change is happening. Humans are largely responsible for
recent climate change. International scientific bodies, federal agencies, and state agencies
have numerous resources that summarize the current scientific understanding of climate
change and the latest projections of climate change impacts.
The Intergovernmental Panel on Climate Change is the leading international body for the
assessment of climate change:
•http://www.ipcc.ch/
The National Aeronautics and Space Administration (NASA) has documented recent
impacts and future trends of climate change:
•http://climate.nasa.gov/effects
The U.S. Environmental Protection Agency (U.S. EPA) has information of climate change,
and it’s effects:
•https://www.epa.gov/climate-research
Cal-Adapt, a product of the Public Interest Energy Research (PIER) program, funded by the
California Energy Commission, provides California-specific climate change research,
including interactive climate tools:
•http://cal-adapt.org/
Carbon Footprint
A carbon footprint is a measure of the total amount of GHG emissions produced by an
individual. It can be thought of as a personal inventory of one’s impacts on climate change.
APPENDIX A: CLIMATE CHANGE INFORMATIONAL RESOURCES

1 Overview
This document presents a summary of the greenhouse gas (GHG) emissions for the City of Carlsbad
(referred to as Carlsbad or the City) for 2012, 2014, and 2016, and the business-as-usual (BAU) emissions
projections for 2035. This BAU projection demonstrates emissions growth in the absence of any new
policies and programs and does not consider future impacts of adopted federal and State policies. GHG
reductions from these policies are considered later in the climate action planning process and are
referred to as the “legislatively-adjusted BAU”.
Section 2 provides background sources and common assumptions used to estimate GHG emissions and
projections. Section 3 provides the GHG emissions for 2012, 2014, and 2016. Details on the methods
used to estimate emissions in each category are provided in Section 4. Section 5 provides a summary of
the emissions projections and the methods used to project future year emissions.
1.1 Rounding of Values in Tables and Figures
Rounding is used only for the final GHG values within the tables and figures throughout the document.
Values for activity data and emission factors are not rounded in the intermediary steps in the calculation.
Because of rounding, some totals may not equal the summed values in tables or figures.
2 Background
2.1 Greenhouse Gases
The primary GHGs included in the emissions estimates presented here are carbon dioxide (CO2),
methane (CH4), and nitrous oxide (N2O). Each GHG has a different capacity to trap heat in the
atmosphere, known as its global warming potential (GWP), which is normalized relative to CO2 and
expressed in carbon dioxide equivalents (CO2e). In general, the 100-year GWPs reported by the
Intergovernmental Panel on Climate Change (IPCC) are used to estimate GHG emissions. The GWPs used
in this inventory are from the IPCC Fourth Assessment Report (AR4),1 provided in Table 1.

2.2 Categories of Emissions
The U.S. Community Protocol for Accounting and Reporting of Greenhouse Gas Emissions (U.S.
Community Protocol), published by ICLEI USA, requires a minimum of five basic emissions-generating
activities to be included in a Protocol-compliant community-scale GHG inventory. These categories are:
1 IPCC Fourth Assessment Report: Climate Change 2007: Direct Global Warming Potentials (2013).
Carlsbad GHG Emissions Inventories and Projection April 13, 2020
Energy Policy Initiatives Center (EPIC) 2
electricity, natural gas, on-road transportation, water and wastewater, and solid waste.2 GHG emissions
are calculated by multiplying activity data (e.g., kilowatt-hours of electricity, tons of solid waste) by an
emission factor (e.g., pounds of CO2e per unit of electricity). For these five categories, methods used in
this inventory were based on the U.S. Community Protocol standard methods and modified with
regional- or City-specific data when available. GHG emissions results are based on the best available
data and methods for each category and are considered the best available estimates.
Additionally, GHG emissions from off-road transportation were included in the inventory and
projections, based on the methods and models used by California Air Resources Board (CARB) in the
statewide GHG emission inventory.3
All activity data and GHG emissions reported in this document are annual values, and all emission
factors reported in this document are annual average values, unless stated otherwise.
2.3 Demographics

The on-road transportation category contributed the most to the overall GHG emissions in all three
inventory years, ranging from 50% to 51%, while the wastewater category contributed the least (<1%) in
all three inventory years.
4 Methods to Calculate GHG Emissions Inventory
4.1 On-Road Transportation
The emissions associated with on-road transportation in Carlsbad were estimated based on the vehicle
miles traveled (VMT) and the average vehicle emission rate in the San Diego region in a given year. VMT
data were provided by SANDAG based on its activity-based model (ABM)5 and the Origin-Destination (O-
D) method.6 The O-D VMT method is the preferred method proposed by the U.S Community Protocol
(TR.1 Emissions from Passenger Vehicles and TR.2 Emissions from Freight and Service Trucks) that
estimates miles traveled based on where a trip originates and where it ends to better attribute on-road
emissions to cities and regions of miles traveled (Figure 2).7 The O-D method is also the preferred
method used across the San Diego region for consistency across jurisdictions.
Figure 2 Components of O-D Method for VMT Calculation
O-D VMT data include miles from all trips that originate and end within Carlsbad City limits, referred to
as Internal-Internal (I-I), and half of miles from trips that either begin within the boundary and end
outside the boundary (referred to as Internal-External, I-E), or vice versa (referred to as External-
Internal, E-I). Miles from trips that begin and end outside Carlsbad that only pass through are referred to
as External-External (E-E). The average weekday O-D VMT estimates for each trip type in 2012 and 2014

The Internal-External and External-Internal miles are divided in half to allocate the miles between
Carlsbad and all other outside jurisdictions. The total VMT is multiplied by 347 to adjust from average
weekday VMT to average annual VMT which includes weekends.9
The average vehicle emission rates expressed in grams of CO2e per mile driven (g CO2e/mile) were
derived from the statewide mobile source emissions model EMFAC2017, developed by CARB.
EMFAC2017 was used to generate CO2, CH4 and N2O emission rates for the San Diego region for all
vehicle classes, model years, speeds, and fuel types.10 The average emission rates were calculated based
on the VMT distribution of each vehicle class and its emission rate. The average CO2, CH4 and N2O
vehicle emission rates were converted to CO2e emission rates based on the GWPs in Table 1.
The total VMT, average vehicle emission rates, and corresponding GHG emissions estimates from the
on-road transportation category from 2012, 2014, and 2016 are given in Table 5.

The average vehicle emission rate in 2014 was lower compared than that in 2012, resulting in lower
emissions in 2014 that might be attributed to higher vehicle emission standards for new vehicles and the
vehicle fleet turnover rate in the San Diego region. The average vehicle emission rate in 2016 was lower
than that in 2014, however, the VMT in 2016 was 4% higher than 2014, resulting in 2016 emissions
approximately the same level as the 2014 emissions.
Figure 3 gives the breakdown of emissions by vehicle class in 2012, based on the EMFAC vehicle class
distribution in the San Diego region, assuming Carlsbad has the same distribution of vehicle types as the
region. Passenger cars contribute the most to emissions with 39%, while motorcycles contribute the
least with 0.4%.11 The breakdown of emissions by vehicle class in 2014 and 2016 are similar to that in
2012.
11 In California’s EMFAC2017, passenger cars are all cars and fuel types designated as Light Duty Automobiles (LDAs). Light Duty
Trucks (LDTs) are classified as LDT1 and LDT2, where LDT1 includes gas, diesel, and electric fuel vehicles, while LDT2 does not
include electric vehicles. Medium-duty trucks included medium duty vehicles (MDV with Gross Vehicle Weight Rating (GVWR)
5751-8,500 lbs), and heavy-duty trucks (HDTs), with GVWR larger than 8,500 lbs. Under the EPA Emission Standard, vehicles
with GVWR under 8,500 lbs are considered light-duty trucks/vehicles

4.2 Electricity
Emissions from electricity use in Carlsbad were estimated using the Built Environment (BE.2) method
from the U.S Community Protocol.12 Annual metered electricity sales by the local utility, San Diego Gas &
Electric (SDG&E) to Carlsbad customers13 were adjusted by: 1) a loss factor14 of 1.0715 to account for
transmission and distribution losses; and 2) subtracting electricity use associated with the distribution of
water to avoid double-counting emissions from the water-energy category.
The basic method to calculate GHG emissions is to multiply the adjusted net energy for load (electricity
sales + losses) by the corresponding City-specific electricity emission factor, expressed in pounds of CO2e
per megawatt-hour (lbs CO2e/MWh). For a given year, the City-specific electricity emission factor is
developed based on the specific power mix of bundled power16 and Direct Access power17 (MWh), and
their respective emission factors (lbs CO2e/MWh). The SDG&E bundled emission factors are calculated

Emissions, Version 1.0 (2012), Appendix C: Built Environment Emission Activities and Sources.
13 2012, 2014 and 2016 metered electricity sales were provided by SDG&E (May 11, 2017).
14 The transmission and distribution loss factor is used to scale end-use demand or retail sales to produce net energy for load. L.
Wong, A Review of Transmission Losses In Planning Studies, CEC Staff Paper (August 2011). 15 California Energy Commission (CEC): California Energy Demand 2015–2025 Final Forecast Mid-Case Final Baseline Demand
Forecast Forms, SDG&E Mid. The transmission and distribution loss factor is calculated based on the ratio of net energy for load (total sales + net losses) and total sales from SDG&E Form 1.2 Mid.
16 SDG&E bundled power includes the electricity from SDG&E-owned power plants and the electricity from its net
procurements.
17 Direct Access refers to electricity that customers purchase from non-SDG&E electric service providers (ESPs), but SDG&E still
provides transmission and distribution services. See SDG&E Direct Access Program.

using Federal Energy Regulatory Commission (FERC) Form 118 data, the California Energy Commission
(CEC) Power Source Disclosure Program19 data on SDG&E-owned and purchased power, and U.S.

(eGRID)20 on specific power plant emissions. The DA emission factor is taken from the California Public
Utilities Commission Decision D.14-12-037.21 The City-specific emission factor are provided in Table 6.
The differences in the electricity emission factors over the years reflect the change in the electricity
power mix in the City and in SDG&E’s service territory from 2012 to 2014. In the later years, more
renewable resources were included in the power mix that have resulted in the decrease of the
electricity emission factors. SDG&E had 32% and 43% renewable sources in the electricity supplied to its
bundled customers in 2012 and 2014, respectively, increased from 19% renewable sources in 2012.22
The net energy for Carlsbad’s load (electricity sales + losses), electricity emission factors, and
corresponding GHG emissions from the electricity category for the years 2012 and 2014 are given in

SDG&E 2017, Energy Policy Initiatives Center 2020.
The GHG emission factor and emissions from the electricity category decreased from 2012 to 2014 most
likely due to the increase of renewable content in the electricity supply. The net energy for load in 2016
is 21% higher than that in 2014. One of the reasons for the increase in net energy for load is likely due to
the electricity use at the Carlsbad Desalination Plant for potable water treatment. The Carlsbad
Desalination Plant treats water for the San Diego County Water Authority, which is the water wholesaler
in the San Diego region. Based on the Plant’s Energy Minimization and Greenhouse Gas Reduction Plan,
the high energy efficiency plant design will lead to 4,398 kWh per acre-foot (AF) of water treatment

energy intensity.24 In 2016, the Plant treated approximately 40,000 AF of water, which resulted in
approximately 177,000 MWh electricity use.25
The emissions can be further separated into residential and non-residential classes. In 2012, 66% of
estimated emissions were attributed to non-residential electricity use and the remaining 34% to
residential electricity use, as shown in Figure 4.

The net energy for load does not include self-serve renewable supply from behind-the-meter
photovoltaic (PV) systems or self-serve non-renewable supply. The behind-the-meter PV systems in
Carlsbad increased significantly from 2012 to 2016. The number and capacity of newly added PV
systems in each of the inventory years, and the total capacity at the end of each inventory year are

Emissions from natural gas end-use in Carlsbad were estimated using method Built Environment (BE.1)
from the U.S Community Protocol.27 Annual metered natural gas sales were provided by SDG&E.28 The
natural gas use was adjusted to exclude the electricity generation fuel use at the Encina Power Station.29
To estimate emissions from the combustion of natural gas, fuel use was multiplied by an emission factor
for natural gas based on data from CARB.30 The natural gas use and corresponding GHG emissions from
the natural gas category are given in Table 8.

4.4 Solid Waste
Emissions from solid waste disposed by Carlsbad were estimated using method Solid Waste (SW.4) from
the U.S. Community Protocol.31 To estimate emissions, the amount of waste disposed by a city in a given
year is multiplied by an emission factor for mixed solid waste. Solid waste disposal data were retrieved
from the California Department of Resources Recycling and Recovery (CalRecycle) Disposal Reporting
System (DRS).32
The emission factor of mixed solid waste depends on the percentage of each waste type within the
waste stream disposed in a landfill. The closest city to Carlsbad with a recent waste characterization
study is the City of Oceanside, therefore this was used as a substitute for Carlsbad to determine the
emission factor based on the percentage of each waste type within the mixed solid waste. This emission
factor was applied to 2012, 2014, and 2016 waste disposal for the emission calculation.33 Only the CH4
emissions from waste degradation, which are considered non-biogenic, are included in this category.
The CO2 emissions from waste degradation are considered biogenic and not included in this category.
The default capture rate of CH4 emissions from landfills is 75% based on the U.S. Community Protocol
and it is the rest that comprises emissions from the solid waste category. The total and per-capita solid
waste disposal and the corresponding GHG emissions from solid waste disposal are given in Table 9. The
waste disposal and GHG emissions from waste in 2016 are 40% higher than in 2012.

4.5 Off-Road Transportation
The emissions from off-road transportation in Carlsbad such as gasoline and diesel fuel use for off-road
vehicles and equipment, were estimated based on CARB off-road models. OFFROAD2007 is the main
model for estimating off-road transportation emissions. After the release of OFFROAD2007, CARB has
been developing inventories and models for each sub-category based on specific regulatory
requirements. For example, the recreational equipment category in OFFROAD2007 was replaced by
RV2013. In this section, new inventories and models were used if available; otherwise, OFFROAD2007
was used. 34
Due to the lack of jurisdiction-specific data from CARB models, the emissions or fuel consumption from
the CARB model outputs for the San Diego region were scaled to the City based on sub-category-specific
scaling factors. The off-road activity sub-categories that are relevant to Carlsbad and the scaling factors
are given in Table 10.35 The sub-categories do not include all sub-categories identified in CARB off-road
models, they are the off-road sub-categories included in the 2015 Carlsbad Climate Action Plan.36

4.6 Water
The Carlsbad Municipal Water District (CMWD) is a SDCWA member agency that provides both potable
and recycled water service within the City of Carlsbad. CMWD services the majority of the City within
the potable water service area and covers 77% of the City population.38 The remaining portion of the
City is served by Olivenhain Municipal Water District (OMWD) and Vallecitos Water District (VWD).39
100% of the City’s potable water supply is imported water from SDCWA.40 The potable water supplied
within CMWD service area and within the entire City is given in Table 12.41
37 The population scaling factors were calculated based on the 2012–2014 populations compared with the regional population.
The regional population is from the SANDAG Demographic & Socio-Economic Estimates (Updated in September 2015),
download date: October 29, 2015. Regional commercial jobs in 2012 are from the SANDAG Series 13 Regional Growth Forecast
(Updated in October 2013), download date: March 29, 2017, SANDAG Data Surfer. Commercial jobs include all employment
types other than agriculture and mining, construction and manufacturing. The jobs estimate in 2013 is interpolated linearly
based on 2012 and 2020 jobs estimates.

The energy used to produce and provide potable water from each type of water is different due to the
different raw sources and their locations. Emissions from water use in Carlsbad were estimated using
method Wastewater and Water (WW.14) from the U.S. Community Protocol.42 The method considers
each segment of the water system (upstream supply and conveyance, local water treatment, and local
water distribution) individually, as described below.
Upstream Supply and Conveyance – This is defined as supply and conveyance of water from the raw
sources to the local service area. The upstream supply and conveyance energy use for imported water
from SDCWA water consists of conveyance of water from the State Water Project and Colorado River
through Metropolitan Water District’s service area and SDCWA’s service area before reaching the City.
Local Potable Water Treatment –This is the energy used for water treatment plant operations. CMWD
imports treated water directly and does not own a water treatment plant. Therefore, there is no energy
used from local water treatment.
Local Potable Water Distribution – This is defined as the energy required to move treated water from
water treatment plants to end-use customers. Distribution energy use includes energy use for water
pump stations and/or pressure reduction stations, water tanks, etc.
The energy intensity per unit of potable water for each segment of the water system is given in Table 13.

Emissions. Version 1.0. (2012). Appendix F. Wastewater and Water Emission Activities and Sources.

MWD 2016, SDCWA 2016, City of Carlsbad 2018.
For upstream supply and conveyance, the potable water amount was multiplied by the upstream energy
intensity to get the total electricity use from upstream supply. This electricity use was multiplied by the
average California electricity emission factor to calculate the GHG emissions.45 Because the electricity
use and GHG emissions associated with upstream supply and conveyance are outside the City boundary
and would not be included in the electricity category, they are accounted for instead in the water
category.
For water distribution emissions, the potable water amount was multiplied by the energy intensity for
local water distribution and the SDG&E electricity emission factor. The electricity and GHG emissions
associated with water distribution occur within the City boundary, and have been subtracted from the
electricity category, as they are accounted for in the water category.
In addition to providing potable water, CMWD delivers recycled water within the entire City.46 The
recycled water delivered by CMWD is from three sources: 1) the Carlsbad Water Recycling Facility
(WRF), 2) the Meadowlark WRF, and 3) the Gafner WRF. The Carlsbad WRF is owned by CMWD but
operated by the Encina Wastewater Authority (EWA). The Meadowlark WRF is owned by VWD and the
Gafner WRF is owned by Leucadia Wastewater District (LWWD), but both agencies sell the recycled
water to CMWD for distribution.47 Recycled water is supplied to golf course, parks, industrial areas, and
homeowner association common areas, etc. The recycled water energy intensity, 588 kWh/acre-foot, is
based on a regional analysis for the North San Diego Water Reuse Coalition (NSDWRC) is used as the
best estimate for the City. 48
43 Since climate action plans (CAPs) consider the jurisdiction as the unit of analysis, water-related GHG emissions associated
with its water use begin at the jurisdiction’s water supply agency or district. Anything upstream of the agency or district is
considered part of upstream supply and conveyance. Therefore, the upstream supply and conveyance energy intensity for
SDCWA treated water for CMWD includes conveyance from the State Water Project and Colorado River water to MWD’s
distribution system, distribution from MWD to MWD’s member agencies, SDCWA conveyance of raw water to its water
treatment plants, treatment in SDWCA’s plants, and distribution of treated water from SDCWA’s treatment plant up to
SDCWA’s member agency. SDCWA 2016: Urban Water Management Plan 2015, Metropolitan Water District of Southern
California, Urban Water Management Plan 2015. EPIC Technical Report: Energy-for-Water Nexus in Cities in San Diego County

staff (January 2018) and used as a proxy for the inventory years.

46 CMWD delivers recycled water within its service area and also adjacent agency service areas. CMWD is the only recycled
water provider within the City. The recycled water distribution area is less than half of the City.

A significant amount of energy is associated with end-use water, such as water heating and cooling.
These emissions are included in the electricity and natural gas category, as data are not available to
separate out those values.
4.7 Wastewater
The emissions from wastewater generated by Carlsbad were estimated based on the total amount of
wastewater generated in a given year and the emission factor of the wastewater treatment processes.
The wastewater in Carlsbad is collected and delivered to the EWA for treatment at the Encina Water
Pollution Control Facility (Encina WPCF). The wastewater treatment GHG emissions and total
wastewater flow for the Encina WPCF were provided by the Encina Wastewater Authority. In 2013, the
Encina WPCF treated an average of 22.8 million of gallons per day (MGD) with annual CO2e emissions of
11,359 metric tons. This resulted in an emission factor of 1.37 MT CO2e/million gallons treated, which
consists of emissions from: 1) stationary combustion of anaerobic digester gas; 2) process emissions
from wastewater treatment with nitrification and denitrification; and 3) direct anaerobic digester gas.
The wastewater emission factor derived from the Encina WPCF was applied to all wastewater flow in the
City of Carlsbad. As similar data were not available for the other years, the 2013 emission factor was
used as an estimate for all inventory years.
The wastewater treated, as well as the corresponding GHG emissions are given Table 15.50
49 Recycled water delivered by CMWD (2012-2016) were provided by City staff (January 2018).

5 Business-as-usual (BAU) GHG Emissions Projections
To inform the development of GHG reduction strategies within a jurisdiction’s Climate Action Plan (CAP),
GHG emissions are projected from the latest data available, as well as projections for population,
housing, and job growth. This is used to develop a business-as-usual (BAU) projection, which
demonstrates emissions growth in the absence of any new policies and programs. Next, emissions
reductions attributable to federal and State policies and programs are applied in the future, creating a
legislatively-adjusted BAU.
Figure 6 provides an illustrative example of the difference between a BAU and a legislatively-adjusted
BAU. Only the BAU projection is discussed in this document; GHG reductions from the policies and
programs included in the legislatively-adjusted BAU are considered in the climate action planning
process.
Figure 6 Illustrative Example Only: BAU and Legislatively-adjusted BAU Emissions Projections

5.1 Emissions Projections for 2035
The total GHG emissions in 2035 are estimated to be 956,000 MT CO2e based on projection methods by
category described below. Figure 7 below shows a comparison of the emissions breakdown by category
for the inventory years (2012, 2014, and 2016) and projection year 2035.
Figure 7 BAU GHG Emissions Projections (Carlsbad, 2035)
As shown in Figure 7, the on-road transportation category remains the largest component of overall
emissions in the projection year, but is not projected to be higher than the transportation emissions in
inventory years. The decline of on-road transportation emissions is likely due to the decline of average
vehicle emission rates, as newer, more efficient vehicles replace old vehicles in the region. The total and
breakdown of projected emissions in each category are presented in Table 16.

5.2 Methods to Project GHG Emissions
The Series 14 Regional Growth Forecast included in the SANDAG 2019 Federal Regional Transportation
Plan was used to obtain the population and job growth in Carlsbad. As of March 2020, SANDAG Series 14
Growth Forecast does not have a breakdown of the number of jobs by employment type (e.g.,
construction, agriculture) for each jurisdiction. Therefore, the ratio of the number of jobs by each
employment type to total number of jobs from SANDAG Series 13 Growth Forecast were applied to the
jobs forecast From Series 14.51 The projected population and jobs in 2035 are shown in Table 17.

Each category was projected to future years using a method specifically for the category as described in
the sections below.
5.2.1 On-road Transportation
Average weekday O-D VMT forecasts for each trip type in 2035 were estimated based on SANDAG Series

VMT of each type was converted to total VMT using the method discussed in Section 4.1. The VMT was
multiplied by the adjusted average vehicle emission rate derived from EMFAC2017 for each projection
year. Two adjustments were made to the EMFAC2014 emission rate: 1) the electric vehicle penetration
rate in 2016 was kept constant for all projection years53, 2) for all new vehicles entering the fleet after
2016, the emission rates are equal to the emission rates of new model year 2016 vehicles with the same
vehicle class and fuel type.54
The projected total VMT, average vehicle emission rates, and corresponding GHG emissions from the
on-road transportation category are given in Table 19.

5.2.2 Electricity
Electricity use in the City was projected separately for residential, commercial and industrial customer
classes. For the residential customer class, the per-capita electricity use (metered electricity sales) in
2014 (2,159 kWh/person/year), was calculated by dividing the total electricity sales in the residential
class by the population. The per-capita electricity use was held constant and used to project total
electricity use for a future year by multiplying by the SANDAG Series 14 population forecast for the
future year. The projected total electricity use was multiplied by the City-specific electricity emission
factor in 2016 (545 lbs CO2e/MWh), held constant, for a projected total GHG emission.
53 The fixed 2016 electric vehicle penetration rate is used to remove the impact of the state Zero Emission Vehicle (ZEV)
program on BAU emissions. The ZEV program requires auto manufacturers to make and sell ZEVs that will increase VMTs driven
by ZEVs.
54 This uses a fixed actual emission rate of the new 2016 models instead of the effect of adopted federal and state vehicle
efficiency standards 2017-2025 for light-duty and heavy-duty vehicles.
Carlsbad GHG Emissions Inventories and Projection April 13, 2020
Energy Policy Initiatives Center (EPIC) 21
A similar method was used for the commercial and industrial class emissions projections. The total
commercial electricity use was projected based on job growth and the per-job electricity consumption in
2016 of 6,936 kWh/commercial job/year. For the industrial class, the electricity use at the Carlsbad
Desalination Plant (177,000 MWh in 2016) was kept constant, and the remaining industrial electricity
use was projected based on the industrial job growth (10,126 kWh/industrial job/year) for all future
years. The total projected net energy for load (electricity sales + transmission and distribution losses)
and corresponding GHG emissions from the electricity category are given in Table 20.55

5.2.3 Natural Gas
The projection method for the natural gas category is similar to that for the electricity category. The
natural gas use in residential, commercial and industrial classes is calculated separately. The per-capita
residential natural gas consumption (118 therms/person/year) and the per-job natural gas consumption
(151 therms/commercial job/year and 126 therms/industrial job/year) in 2016 were held constant with
population and job growth for the projection. The natural gas emission factor used in Section 4.3 was
held constant. The projected total natural gas use and corresponding GHG emissions from the natural
gas category are given in Table 21.

5.2.4 Solid Waste
Solid waste disposal in Carlsbad was projected using the population growth and the per-capita solid
waste disposed in 2016 (3.5 kg/person/day), to be consistent with other categories. The projected
emissions from the disposal were calculated by multiplying the disposal amount with the emission factor
for mixed solid waste, provided in Section 4.4. The projected total waste disposal and corresponding
GHG emissions from the solid waste category are given in Table 22.
55 The net energy for load of each future year is adjusted using the method described in Section 4.2. The net energy for load
does not include self-serve renewable supply, such as electricity generation from distributed-level solar PV systems.

5.2.5 Off-Road Transportation
In the off-road transportation category, the direct output of OFFROAD2007 (lawn and garden equipment
and light commercial equipment), RV2013 model (recreational equipment), and diesel-fueled potable
equipment for the San Diego region were used and scaled down to Carlsbad based on the scaling factor
as determined in Section 4.5. For the construction and industrial equipment sub-category, the In-Use
Off-Road Equipment 2011 Inventory does not include emissions output after 2030. For the projection
years 2020 and 2030, the direct output for the San Diego region from the model was used and scaled
down to Carlsbad. For 2035, the emissions were estimated based on the commercial and industrial job
growth. The projected total and sub-category off-road transportation emissions are given Table 23.

5.2.6 Water
The total water use for all projection years was determined using the same method as the solid waste
section and was based on 2016 per-capita water consumption and population growth. It is assumed that
no new potable or recycled water source is developed under the BAU projection.
The per-capita water supplied in 2016 was 141 gallons/person/day for potable water and 32
gallons/person/day for recycled water. The energy intensity for each element of the water cycle (Table
13) and the electricity emission factor were held constant for all projection years. The projected total
potable water supplied and corresponding GHG emissions from the water category are given in Table
24.

5.2.7 Wastewater
The total wastewater generation for all projection years was determined using the same method as the
solid waste and water sections, based on 2016 per-capita wastewater generation and projected
population growth. The per-capita wastewater generated in 2016 (53 gallons/person/day) and the
emission factor derived from data based on the Encina Wastewater Authority (Section 4.7) was held
constant for all projection years.
The projected total wastewater generated and the GHG emissions from the wastewater category are
given in Table 25.

MEMORANDUM
To: David de Cordova
From: Chris Ford
Re: Carlsbad Government Operations Greenhouse Gas Inventory Update – 2011
Date: June 18, 2013
This memo summarizes the approach taken to update the 2005 Greenhouse Gas (GHG)
Emissions Inventory from City of Carlsbad government operations with 2011 data and
compares the inputs and outputs. A separate memo covers community emissions, updated
with 2011 data. That memo is referenced in this one to minimize repetition of information.
The content of these memos will contribute to the summary of Carlsbad’s GHG emissions in
the forthcoming Climate Action Plan (CAP); the memos may be placed in an appendix to the
CAP.
Technical terms and acronyms that appear in this memo are listed in Table 1.

ASSUMPTIONS
As with the 2005 inventory, ICLEI’s CACP1 model was used to estimate emissions from local
government operations across all sectors. Unlike with community emissions, CACP was the
only model employed.
Three sectors analyzed— employee commute, stationary refrigerants, and solid waste—are
“Scope 3” emissions. These emissions are not part of the government operations emissions
inventory as they are indirectly caused by the City, but this memo reports on their impact.
Employees
Between 2005 and 2011, the number of full-time equivalent (FTE) employees at the City of
Carlsbad increased by 4.2 percent, growing from 793 to 826 FTE. This percent change is used
to estimate pro-rated increases in certain emissions since 2005.
Electricity Coefficients
Electricity coefficients measure how much GHG emission and air pollution is created by
various sources of electricity generation. The government operations inventory uses the same
electricity coefficients as the community inventory; see that other memo for a discussion on
the increase in GHG emissions per megawatt hour from SDG&E electricity since 2005.
Natural Gas Coefficients
The default values in the CACP model were used; they are the same as those used in 2005.
Transportation
Local government emissions from vehicles were estimated using the CACP model. For NO2
and CH4 emissions, CACP only includes emissions factors through model year 2005. The
CACP instructions include additional factors that can be manually entered for model years
2006-2008; we also got newer information from the latest US EPA Inventory of US GHG
Emissions and Sinks report, the source used by ICLEI. This 2013 version of the EPA report2
includes newer emissions factors, although the applicable date is not specified; the factors for
gasoline are similar to the 2008 factors, therefore they were applied for model years 2009
onwards. Table 2 shows the emissions factors we entered into CACP for gasoline vehicles
with model years of 2006 and later.

2008 (2010). 2009+ model years from EPA Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-
2011 (2013), Annex 3.
The 2013 EPA report’s emissions factors for diesel are the same as for model years 1996-2004,
so diesel vehicles were handled through the regular CACP calculation.
Solid Waste
The default values in the CACP model were used.
INPUTS AND METHODOLOGY
This section describes the data used to calculate 2011 emissions and the manner in which the
data was acquired, transformed, and used. The table at the end of this section compares the
2005 and 2011 inputs.
Buildings and Other Facilities
The inputs for this sector are electricity and natural gas. Data was entered by individual
facility with departmental information also entered. Since the 2005 inventory through 2011, a
number of new or expanded facilities have been added to the City’s operations: Fire Station
No. 6, Senior Center expansion, Recycled Water Facility, Aviara Community Park, Hidden
Canyon Park, Pine Avenue Park, The Crossings golf course, and the Hawthorne Equipment
Building. During the same period, the Library Learning Center replaced the Adult Learning
Center and Centro de Informacion. These additional facilities account for the majority of the
change in electricity and natural gas consumption.
Table 3 lists all of the buildings and facilities operated by the city, comparing electricity and
natural gas inputs between 2005 and 2011. Overall, the City’s facilities consumed 21 percent
more electricity and 10 percent more natural gas in 2011 compared to 2005.

Public Lighting
This sector covers electricity consumed from three sources: traffic signals, streetlights, and
other outdoor lighting. As shown in Table 4, streetlights make up the great majority of
electricity consumption in this sector. Between 2005 and 2011, this sector consumed 4
percent less electricity, with the small increase in traffic signal and controller use more than
offset by the declines in streetlight and outdoor lighting consumption. During this period, the
city retrofitted its existing streetlights with more energy-efficient lamps.

Water and Wastewater Transport
This sector covers fuel consumed by pumps and other mechanisms used to convey water and
wastewater: water delivery pumps, sprinklers and irrigation, sewage pumps, and recycled
water pump stations. These systems all consumed electricity plus a small amount (170
gallons) of diesel fuel for water delivery generators.
Table 5 shows the electricity consumed by the City’s water and wastewater transport systems
in 2005 and 2011. During that time, electricity used by these systems increased by 29 percent.
Much of that change can be attributed to a major increase in electricity used by recycle pump

stations, as the city’s recycled water facility came online in late 2005. Sewage pumps also used
significantly more electricity (22% increase), as did sprinklers and irrigation (72% increase)
although the amount was comparatively small. Water delivery pumps actually decreased in
electricity consumption by 21 percent.

Vehicle Fleet
The inputs for this sector are all the vehicles used by the City. The key data used are fuel
consumed and VMT, broken out by model year, vehicle type, and fuel type. CACP uses fuel
consumption to calculate CO2 emissions and VMT to calculate NO2 and CH4 emissions.
Although the vehicle fleet data from the City was broken down by department, the inputs
were loaded into CACP as a single set for the entire City due to the time consuming nature of
processing and entering this very detailed information.
Table 6 summarizes the inputs in 2005 and 2011 by vehicle and fuel type. There likely was
some different categorization in terms of vehicle types in 2005, especially between light and
heavy trucks, but overall fuel consumed and VMT by fuel type should be comparable. While
there was a notable increase in diesel consumption and VMT, this was more than offset by a
sharp decline in gasoline consumption and VMT.

For the analysis in CACP, motorcycle inputs were grouped under passenger cars and hybrid
fuel consumption was included with gasoline. Hybrid VMT was assumed at one-third of
listed mileage to account for the likely reality of most hybrid miles being under electric power
during low speed driving on local streets.
Mobile Refrigerants
Refrigerants come from stationary and mobile sources. Stationary sources are described
under Scope 3 emissions.
Mobile source refrigerants come from estimated leakage from the vehicle fleet. The 2005
inventory undertook a very complex and thorough analysis based on attributes of each
vehicle in the fleet, using the make, model, year, and time in service to determine refrigerant
type and capacity and calculate estimated emissions. Ultimately, the GHG emissions from
mobile refrigerants made up less than one percent of government operations emissions in
2005.
Given the small impact of these mobile refrigerants and the time already invested in the 2005
analysis, we used the 2005 output and pro-rated it for 2011 based on the relative sizes of the
vehicle fleet. The 2005 fleet had 264 vehicles compared to 291 vehicles in the 2011 fleet, a 10
percent increase. Therefore, we estimated a 10 percent increase in GHG emissions from
mobile sources for 2011.
Scope 3 Emissions
These emissions are not part of the government operations inventory as they are indirectly
caused by the City.
Employee Commute
The City conducted an employee commute survey in 2009 which was applied to the 2005
inventory. Given that only two years elapsed between the survey and the year of this GHG
emissions inventory update, it was assumed that the mode split, fuel consumption, and VMT
data from the survey were still applicable. As with the 2005 inventory, the results from usable
survey responses were extrapolated to apply to all City FTE. Since the 2011 FTE is 4.2 percent
higher than the 2005 FTE, the fuel usage and VMT inputs for 2011 were 4.2 percent higher
than in 2005.
DYETT & BHATIA
Urban and Regional Planners
Page 8 of 10
Stationary Refrigerants
Stationary sources come from equipment installed in facilities. The 2005 inventory identified
refrigerants used to service equipment in five buildings: Las Palmas, Harding Community
Center, City Administration, the Safety Center, and the Senior Center. The 2011 inventory
identified refrigerant use in four buildings: City Administration, City Hall, Dove Library, and
the Senior Center. Refrigerants use was less in 2011 than in 2005, by around half (117.50 kg
compared to 234.51 kg).
Solid Waste
The City undertook a thorough evaluation of solid waste generated by City facilities in 2005.
Given that solid waste generation is typically correlated to number of people, we pro-rated
the amount of solid waste based on the increase in FTE between 2005 and 2011, which was
4.2 percent.
Sectors Not Considered
The City does not operate port, airport, wastewater, or solid waste facilities, provide transit
services, or generate electric power.
CONCLUSIONS
City operations in 2011 generated an estimated 8,205 metric tons CO2e in GHG emissions,
compared to an estimated 6,556 metric tons CO2e in 2005, an increase of 25 percent, as
shown in Table 7. City operations still accounted for a very small proportion of the GHG
emissions from Carlsbad in 2011, making up 0.8 percent of emissions, the same as in 2005.

The rate of growth in government emissions between 2005 and 2011 was higher than the
rates of increase in Carlsbad’s service population (12.0%) and communitywide GHG
emissions (11.4%). The main reasons for the increase in government operations emissions
appear to be twofold:
• A sharp increase in electricity consumed by water and wastewater transport services,
especially recycled water pumps; and
• More emissions from electricity per megawatt hour, an issue that also affected
communitywide emissions and further discussed in that memo.

Urban and Regional Planners
Page 9 of 10
Emissions by Sector
Emissions for government operations mainly came from buildings and facilities (42%) and
the vehicle fleet (27%), followed by public lighting (21%) and water and wastewater
transportation (10%), as shown in Table 8.
Compared to 2005, the proportion of city government emissions from buildings and facilities
increased from 35 percent to 42 percent, increasing by 50 percent and making up more than
two-thirds of the growth in emissions. As explained above, this is largely due to the opening
of new buildings and recreation facilities since 2005.
Meanwhile, compared to 2005, the proportion of emissions from lighting and
water/wastewater transport stayed largely the same, but the actual emissions from these
sectors grew by 29 percent and 72 percent, respectively. Note that public lighting emissions
increased by despite that sector consuming 4 percent less electricity in 2011 compared to
2005. This outcome is a result of the much greater amount of emissions produced per
megawatt hour of electricity in 2011 compared to 2005.
Meanwhile, vehicle fleet emissions decreased by 9 percent during the same period, due to
major decreases in the miles driven and gallons of gasoline consumed.

Emissions by Source
Most of the government operations emissions in 2011 came from electricity consumption,
accounting for 65 percent of emissions, an increase from 59 percent in 2005. GHG emissions
from electricity increased by 52 percent between 2005 and 2011, as shown in Table 9.
Electricity was the source of almost all of the increase in emissions—more than the total
increase, in fact, but offset by the decline in emissions from gasoline. Emissions from gasoline
dropped by 17 percent, which caused gasoline to decline from 31 to less than 19 percent of
government operation emissions between 2005 and 2011. Emissions from diesel grew by 13
percent and from natural gas and mobile refrigerants by 10 percent each, although all from
relatively small bases.

Sector 3 Emissions
Employee commute and solid waste emissions were estimated for 2011 based on pro-rating
various indicators and loading them into the CACP model for calculation. See the
Assumptions section above for more details.
• Employee commute emissions were estimated at 2,567 metric tons CO2e in 2011,
compared to 2,417 metric tons CO2e in 2005, an increase of 6.2 percent.
• Stationary refrigerant emissions were estimated at 173 metric tons CO2e in 2011,
compared to 399 metric tons CO2e in 2005, a decrease of 57 percent.
• Solid waste emissions were estimated at 144 metric tons CO2e in 2005, the same as in
2011.

CARLSBAD CLIMATE ACTION PLAN
D-3
a. Carlsbad Boulevard shall become more than a road. This transportation
corridor shall provide for recreational, aesthetic and community gathering
opportunities that equal the remarkable character of the land.
b. Community safety shall be a high priority. Create destination that provides a
safe public environment to recreate.
c. Strategic public access and parking is a key to success. Development shall
capitalize on opportunities to add/enhance multiple public access points and
public parking for the beach and related recreational amenities.
d. Open views are desirable and important to maintaining the character of the
area. Preservation and enhancement of views of ocean, lagoons, and other
water bodies and beaches shall be a high priority in road, landscaping, and
amenity design and development.
e. Enhance the area’s vitality through diversity of recreational land uses.
Carlsbad Boulevard development shall provide for amenities, services and
goods that attract a diversity of residents and visitors.
f. Create vibrant and sustainable public spaces. Development shall provide for
unique and vibrant coastal gathering spaces where people of all age groups
and interests can gather to enjoy recreational and environmental amenities
and supporting commercial uses.
g. Connect community, place and spirit. Design shall complement and enhance
connectivity between existing community and regional land uses.
h. Environmentally sensitive design is a key objective. Environmentally sensitive
development that respects existing coastal resources is of utmost importance.
i. A signature scenic corridor shall be created through design that honors the
coastline’s natural beauty. The resulting improvements will capture the
‘essence’ of Carlsbad; making it a special place for people from throughout the
region with its natural beauty and vibrant public spaces. Properly carried out,
the realigned boulevard will maximize public views and encourage everyone
to slow down and enjoy the scenery.
j. Reimagining of Carlsbad Boulevard shall be visionary. The reimagined
Carlsbad Boulevard corridor will incorporate core community values
articulated in the Carlsbad Community Vision by providing: a) physical
connectivity through multi-modal mobility improvements including
bikeways, pedestrian trails, and a traffic-calmed street; b) social connectivity
through creation of memorable public spaces; and c) economic vitality
through a combination of visitor and local-serving commercial, civic, and
recreational uses and services.
2-P.72 Enhance the walkability and pedestrian orientation of the Village, including along
Carlsbad Village Drive, to enhance the small, beach town atmosphere and
improve access to and utilization of transit.
2-P.75 Address parking demand by finding additional areas to provide parking for the
Village and beach areas, and by developing creative parking management
strategies, such as shared parking, maximum parking standards, “smart”
metering, utilizing on-street parking for re-use of existing buildings, etc.
2-P.79 Create a cohesive, pedestrian-scale streetscape that includes improved sidewalks,
streetscape, signage and way-finding, and which celebrates the Barrio’s heritage
and provides better connections between the Barrio and Village and across the
railroad at Chestnut Avenue.
APPENDIX D: APPLICABLE GENERAL PLAN POLICIES

2-P.83 West of the railroad tracks:
Decommission, demolish, remove and remediate the Encina Power Station
site, including the associated structures, the black start unit and exhaust stack
according to the provisions of a settlement agreement dated January 14, 2014,
between and among the City of Carlsbad and the Carlsbad Municipal Water
District (CMWD), Cabrillo Power I LLC and Carlsbad Energy Center LLC,
and San Diego Gas and Electric Company (SDG&E). The desalination plant shall remain on approximately 11 acres (six acres for
the desalination plant and approximately five acres of non-exclusive
easements) west of the railroad tracks. Redevelop the Encina Power Station site, along with the SDG&E North Coast
Service Center site, with a mix of visitor-serving commercial uses, such as
retail and hotel uses, and with new community-accessible open spaces along
Agua Hedionda Lagoon and the waterfront (Carlsbad Boulevard). Encourage
community gathering spaces, outdoor dining, and other features to maximize
potential views of the ocean and the lagoon. Encourage shared parking
arrangements so that a greater proportion of development can be active space
rather than parking. Determine specific uses, development standards, infrastructure, public
improvements, site planning and amenities through a comprehensive
planning process (e.g., specific plan, master plan, etc.) resulting in a
redevelopment plan approved by the City Council. The redevelopment plan
boundaries should include the Encina Power Station and the SDG&E North
Coast Service Center sites. Work with SDG&E to identify a mutually acceptable alternative location for
Its North Coast Service Center. Work with SDG&E, as part of a long-term
plan, to identify and ultimately permit an alternate site for its Encina
substation.
Chapter 3: Mobility
3-P.8 Utilize transportation demand management strategies, non-automotive
enhancements (bicycle, pedestrian, transit, train, trails, and connectivity), and
traffic signal management techniques as long-term transportation solutions and
traffic mitigation measures to carry out the Carlsbad Community Vision.
3-P.15 Evaluate methods and transportation facility improvements to promote biking,
walking, safer street crossings, and attractive streetscapes. The City Council shall
have the sole discretion to approve any such road diet or vehicle traffic calming
improvements that would reduce vehicle capacity to or below a LOS D; this also
applies to streets where the vehicle is not subject to the MMLOS standard as
specified in Table 3-1.
3-P.16 Design new streets, and explore funding opportunities for existing streets, to
minimize traffic volumes and/or speed, as appropriate, within residential
neighborhoods without compromising connectivity for emergency first
responders, bicycles, and pedestrians consistent with the city’s Carlsbad Active
Transportation Strategies. This should be accomplished through management
and implementation of livable streets strategies and such programs like the
Carlsbad Residential Traffic Management Plan.
CARLSBAD CLIMATE ACTION PLAN
D-5
3-P.17 Consider innovative design and program solutions to improve the mobility,
efficiency, connectivity, and safety of the transportation system. Innovative design
solutions include, but are not limited to, traffic calming devices, roundabouts,

3-P.31 Engage the community in the policy setting and planning of street, bicycle,
pedestrian, transit, and connectivity studies, plans and programs.
3-P.32 Require developers to improve pedestrian and bicycle connectivity consistent
with the city’s bicycle and pedestrian master plans and trails master planning
efforts. In addition, new residential developments should demonstrate that a safe
route to school and transit is provided to nearby schools and transit stations
within a half mile walking distance.
3-P.33 Work with existing neighborhoods and businesses to improve pedestrian and
bicycle connectivity and safety consistent with the city’s pedestrian and bicycle
master plans and trails master planning efforts.
3-P.34 Actively pursue grant programs such as SANDAG’s Active Transportation Grant
Program and Smart Growth Incentive Program to improve non-automotive
connectivity throughout the city. The emphasis of grant-funded projects shall be
on implementation, which includes planning documents that guide and prioritize
implementation, programs that encourage the use of active transportation modes,
education for the use of active transportation modes, or physical improvements
themselves.
3-P.35 Partner with other agencies and/or developers to improve transit connectivity
within Carlsbad. As part of a comprehensive transportation demand management
(TDM) strategy and/or with transit oriented development (TOD), a shuttle
system could be established that connects destinations and employment centers
like LEGOLAND, hotels, the Village, McClellan-Palomar Airport, business parks,
CARLSBAD CLIMATE ACTION PLAN
D-7
the COASTER and Breeze transit stations, public activity centers (such as senior
centers, city hall, libraries, etc.) and key destinations along the coast. The system
could incorporate shuttle service in adjacent cities to maximize connectivity.
3-P.36 Encourage NCTD, SANDAG and other transit providers to provide accessibility
for all modes of travel to the McClellan-Palomar Airport area.
3-P.38 Develop flexible on-site vehicle parking requirements. Such requirements will
include implementation of innovative parking techniques, implementing effective
TDM programs to reduce parking demand, and consideration of other means to
efficiently manage parking supply and demand.
3-P.39 Require new employment development to provide secure bicycle parking on-site.
Major employers should provide shower and changing rooms for employees as
appropriate.
3-P.40 Assist Village businesses to manage parking in the Village area to maximize
parking efficiency. Any potential parking-related revenues generated in this area
should be reinvested into the Village area for implementing livable streets and
other parking, pedestrian, and bicycle enhancements, including way-finding
signage and maintenance of associated infrastructure.
3-P.41 Consider supporting new development and existing businesses with various
incentives (such as parking standards modifications) for implementing TDM
programs that minimize the reliance on single-occupant automotive travel during
peak commute hours.
Chapter 4: Open Space, Conservation, and Recreation
4-P.40 Prepare a comprehensive Trails Master Plan update, that expands the existing and
planned 61-mile trail system, with the following objectives:
Connectivity between off-road trails and major on-road pedestrian and
bicycle routes, such that future improvements in the trail system also
contribute to linkages between important sites (beaches, lagoons, schools,
commercial centers, master planned communities, and others) Design and designate trails as multi-use to be accessible for all user groups,
including walkers, bicyclists, and equestrians (as land use policy allows).
Ensure that the network provides an appropriate amount of resources for
each trail type or user group Greenway and trail linkages from major recreational/open space areas to
other land use areas or activities, including, but not limited to, residential
neighborhoods, places of employment, parks, schools, libraries, and
viewpoints Linkages/multi-use trails connecting businesses and residential

This CAP Amendment has made further changes in the provisions related to TOM and alternative

provisions of our lawsuit settlement agreement, including once earlier this month. There has been no
response.
There is an error in recording the computations for TOM resulting in a near doubling of the calculated amount
of GHG emission reductions. This has not been corrected or explained. Furthermore the detailed actions
proposed fail to achieve the stated goal or to make any meaningful increase in the use of alternative
transportation. ·

Comments on# 17-CAP Amendment# 1
All Receive-Agendiil Item# LJ
For the Information of the:
~IT:f. ~OUNCIL
Date ~CA ~c _::::
CM --P.CM _ ...-UCM (3) _:::--
We beHeve you are committed to a Climate Action Plan that complies with state law.and actually reduces Carbsbad's
greenhouse gasses (GHG). But for those of us who have been working on these issues for many years this CAP
Amendment is very concerning. In January staff acknowledged a major error in the original CAP computations for
Vehicle Miles traveled (VMT). This amendment is intended to correct that error, and make other changes to reflect . .
current methods of computing GHG inventory and reduction measures. The magnitude of these changes now makes
any historical comparison invalid, and leaves us at risk of other computational errors going forward. The bottom line is
any meaningful analysis of actual results remains problematic at best, and is still years in the future.
It is 5 years since the original CAP was adopted and we still have no way of answering the critical question-Are GHG
emissions declining in Carlsbad?
The following highlights a few of our concerns:
Note-numbers in ( ) refer to Agenda Packet electronic page number
-No clear explanation for the. changes on Table 2-2 Community GHG Emissions (489 and 493)
The total emissions increased by over 38% from 705,744 to 977,000 MT -with increases in all sectors except
wastewater water which went down by over 50%. There is no way to verify the numbers that are shown-and they are
critical as they establish the baseline.
Recommendation : Add a technical appendix that shows all of the source data and computations so these can be verifiep
and replicated over time. This is especially important given the major error that occurred with the original CAP .
. -This VMT data is not consistent with the latest data from SAN DAG
( 489-Note the referenced Appendix B-1 is not included)
This amendment is now based on 2012 data, but SAN DAG has posted 2016 data. Furthermore the SAN DAG data shows
increases in regional VMT /capita and VMT/employee between 2012 and 2016 yet the CAP assumes VMT in Carlsbad is
declining. We checked several of the census tracts in Carlsbad, and all showed a VMT increase between 2012 and
2016.
sandag.maps.arcgis.com/apps/webappviewer/index.html?id=Sb4af92bc0dd4b7babbce21a7423402a
Recommendation : The most current SAN DAG data should be used-and inhere is a discrepancy it should be explained.
-2020 GHG reductions from General Plan have all been deleted (532)
The original CAP on Table 3-2 identified several GHG reductions from General Plan Policies and Actions . These included
bikeway, pedestrian, traffic calming, parking and transportation improvements. These now have 0 GHG reductions for
1
2020. Does this mean less has been done than was assumed when the CAP was adopted in 2015-or is this just another
"computational" error?
-Actions do not support the TDM goal of a 10% increase in alternative transportation to a total of 32% use . (551)
A goal is meaningless unless it is supported by actions that have a reasonable chance of achieving it. The new, detailed
computations of changes identify the following reductions potentially related to alternative transportation by 2035:
Bikeways .07 % reduction in VMT (524)
Connectivity and Pedestrian improvements 1.00 % (526)
Traffic calming .25
Transportation .63
Parking policies 2.00
Total 3.95 %
(531)
(529)
There is nothing that explains how this minimal reduction in VMT could resul,t in such a dramatic increase in the use of
alternative transportation. Parking is the action with the greatest reduction and that seems questionable given the
recent Planning Commission approval of the Carlsbad Corporate Plaza Parking Structure on 6/3/20 with no VMT <Jnalysis
and that is not consistent with the General Plan parking policies.
Also note that the emission reductions for Transportation increased from 1,327 to 2,085 MT (532) yet there is no change
in the detailed computations for this measure (531). This is an obvious error.
This CAP amendment fails to provide essential information to ensure that you, or the general public, have any
assurances that GHG will be reduced in your city.

Subject: RE: Amendment 1 to CAP
Hi Paige,
Thanks for your email and, as always, I'm happy to answer any questions you and/or others may have.
Responses to your listed items are below in green. We requested EPIC provide more data regarding the
calculation of the CCE emissions reductions and will forward that to you as soon as it's received. I thought it
best to send the remaining information since it was available. If you haven't already explored it, the SAN DAG
Regional Action Planning Framework (ReCAP) provides a lot of detail on how inventories (Technical Appendix
1
!) and emissions reductions (Technical Appendix II) are calculated. EPIC used these methodologies in preparing
its report (Appendix B-1 of the proposed CAP).
The VMT calculation error, and its resulting impact on the CAP, is documented in previous staff reports. For a
perspective on the approximate magnitude of the error, you can compare the VMT in Appendices B-1 and B-2
ofthe existing CAP. Appendix B-1 is the original ICLEI 2005 GHG inventory and Appendix B-2 contains the Dyett
& Bhatia 2005 and 2011 inventories. Please be aware that the ICLEI 2005 VMT was calculated using an older
methodology so the numbers are not directly comparable. A discussion of the evolution of the CARB Scoping
Plan guidance is contained in Section 3.1 of the proposed CAP amendment.
The Environmental Management Department is currently working with Planning Division to analyze the
potential GHG emissions impacts related to the General Plan Housing Element update. We have yet to
determine the level to which additional programmatic CAP measures will be needed. I have already been in
communication with Simon about his EV proposal. If you would like, we can meet to discuss that and any
other measures you would be interested in the city exploring. At that meeting, or on another occasion, we
could meet with EPIC to discuss in more detail the derivation of the inventories and emission reduction
projections. That way you can ask them questions directly in real time. Please let me know if you're interested
in meeting about these or other CAP-related topics and who would like to attend, and I can send out a
meeting availability poll.
Thanks again,

Subject: Amendment 1 to CAP
Dear Mike,
2
In preparation for the council meeting on July 14 to amend the Climate Action Plan to include Community
Choice Energy, our Carlsbad Sierra Club My Gen team is hoping you'll consider some of the points we asked
for in our original public comments listed below from the May 12 council meeting which are not clear in the
revised\plan in addition to a few more issues. Quite frankly, the information at this (May 12) meeting was no
more elucidating than the original Jan. 21, 2020 meeting so we're hoping you'll provide more details du ring
this upcoming meeting.
The Jan. 13, 2020 letter from the city attorney to the city manager points out "the CAP's VMT calculation is
based on an incorrect input, which resulted in a materially understated (emphasis added) greenhouse gas
(GHG) inventory and GHG targets."1 We interpret this as a major problem with the GHG inventories for our
CAP. Given our confusion between the original 2015 CAP and the amended 2020 CAP, we suggest that within
the Introduction of the revised CAP, a paragraph be included explaining the VMT problem (either in 1.1
Introduction or 1.5 under 'How this plan was prepared') and that the CA Air Resources Board (CARB) has
changed how 2020 and 2035 targets are calculated.
At a minimum, and in the interests of full government transparency, all calculations that support Carlsbad
meeting its 2020 GHG targets should be made public. It would be most helpful if for 2012, 2014, and 2016
inventories, a breakdown by sector could be provided so progress in each sector could be assessed .
While we join Staff in recommending the City add a CCE to the CAP, it is unclear the savings in GHG emissions
we can expect from the Clean Energy Alliance. The EPIC report did not address this additional measure.
In preparation for your upcoming council meeting our team requests that the following be provided or carried
out:
• Since the 2012 Community GHG emission-by-category table and figure in chapter 2 is our baseline,
please provide the same breakdown for the following years, 2014 and 2016, to show the progression
of emission reductions. (See EPIC April 2020 Amendment 1 graph and table) A su mmary of t he GHG
em iss ions-by-category, along with a bar graph indicating their percentages, is contained on page 3 of
Appendix B-1 (EPIC's April 2020 report).
• In Table 3-1, correct the 2020 and 2035 targets which appear to be off slightly per the CARB guidelines.
Tab les 3-1 and 4-2 have been corrected to show the 2020 target as 937,920 and 2035 target as
468,960.
• Clarify (sec. 3.2) how the desalinization plant emissions are accounted for as we can find no mention of
the plant in the amended CAP. The GHG emissions from the desa li nation plant's energy con su mption,
which began operation in Dec. 2015, are included in t he 2016 inventory's community-wi~e electricit y
consumption and resu lting GHG emissions. Privacy ru les by the CP UC do not al low the city to rece ive
3
disaggregated data, therefore the exact consumption of any customer, including desalination plant, is
not known.
• Provide the calculations showing the 56,000 MTCO2 savings from CEA; it's not clear from the feasibility
study where this number came from. The feasibility study was used to choose which CCE scenario
would be modeled for the CAP measure. The GHG reduction calculations were derived using the EPIC
GHG model and involve interactions with other CAP measures (i.e. they are not simply the difference
between SDG&E's and CCE emissions factors). EPIC is preparing a table to show these considerations,
which will be provided to you upon completion. Please also note that the proposed Clean Electricity
Measure P contains an action to explore the purchase of renewable energy credits if CCE is not
reaching the 2035 goal.
• Quantitate the effectiveness of the CAP actions taken to date. For 2035 targets many of the numbers
depend upon "encourage" or "promote" strategies (D-G, K, O). To the extent this is feasible, the CAP
Annua l Report includes this data. For CAP measures t hat rely upon energy consumption data (e.g.
Measure 50% reduction energy reduction in 30% of households), calculating the progress in reaching
the goal requires data from SDG&E. The most recent data from SDG&E (2018) was just received and
will be included in the Reporting Year 4 Annual Report. We need to know how effective existing
strategies are. We would also encourage aggressive outreach sooner than later. While the titl.es of
Measures D, E, F and Kuse the words "encourage" or "promote," the actions contained in the Measure
include implementation of the CAP ordinances, in addition to the promotional and educational actions.
The effectiveness of each measure is gauged by the progress in reaching the overall goal for the
respective Measure. Note: Measure G is deleted in this amendment (see page 4-7).
• Prioritize an entire CAP update as soon as possible. City staff is prepared to recommend a
comprehensive CAP update once budget is available. If possible, this issue will be revisited later during
this fiscal year.

Subject: 7.14.20 council meeting item #17 public comment
Please include the following public comment at today's council meeting:
Dear Mayor and city councilmembers,
I've been doing my best over the last couple of months to work through the changes in our GHG emissions due
to the Vehicle Miles Travel error made in the original 2015 Climate Action Plan. With all the corrections it is
quite a task to move from the original CAP to the amended one you're looking at today.
While one can dig through the agenda packets to follow the path of corrections, it seems best to include the
sequence of errors and corrections within the updated CAP itself for those interested in a historical
perspective. I'm asking you consider including in the CAP, perhaps as an appendix, language explaining the
original error. Also, all calculations used to justify significant targets need to be included as part of full
transparency to the public.
Specifically, the amended document should
1. Show calculations and sources of reductions in GHG for the 2020 target.
2. Add how EPIC determined the contribution from Community Choice Energy in meeting the 2035
target. By the way, there seems to be an error in this calculation, another indication why full
disclosure of these numbers is imperative.
In addition, I encourage staff to determine a better way of assessing the effectiveness of CAP ordinances other
than aggregate electricity data from SDG&E. We need more measurable outcomes for our CAP actions to see
whether the city's GHG reduction steps work.
I do thank Mike Grim for readily supplying the changes to the updated CAP and the EPIC CCE calculations as
well as addressing a number of concerns. I look forward to greater transparency in the next round of CAP
updates.
Respectfully,
Paige DeCino

Thank you.

RE: Agenda Item #17 — Amendment No. 1 to the Climate Action Plan
Dear Honorable Mayor and City Council Members,
San Diego Gas & Electric Company (SDG&E) appreciates the opportunity to provide input on
the City of Carlsbad's Climate Action Amendment. We share the City's ambitions for achieving
reductions in greenhouse gas (GHG) emissions and are committed to supporting long-term goals
in this space.
The City of Carlsbad's CAP aligns well with SDG&E's mission to build the cleanest, safest, and
most reliable energy infrastructure company in America and have among the cleanest energy
portfolios in the nation. Currently, we are delivering around 45% renewable energy to all our
customers, including residents, businesses located within the City of Carlsbad — and that number
does not include rooftop solar, which is additive to that already nation-leading figure. Due to our
forward-looking planning for the procurement of renewable energy, SDG&E is well-positioned
to meet the 60% Renewable Portfolio Standard (RPS) by 2030 as outlined in Senate Bill 100.
Additionally, SDG&E remains supportive of the member cities of the Clean Energy Alliance
(CEA) and continues to meet regularly with CEA staff and their consultant team to collectively
prepare for the 2021 launch. We continue to be a phone call away to answer questions and are
working with their integration consultants to ensure information and financial flows are as
seamless as SDG&E has the ability to make them.
Given that half the GHG emissions in the City come from on-road transportation, we think
focusing on driving clean is critical for any measurable impact of GHG emissions reductions. As
our regulators have noted, every municipality in the State of California could procure 100%
renewable energy and we still wouldn't meet our collective climate reduction goals. We need to
focus on clean transportation for GHG reduction, health, national security and economic reasons.
That is why SDG&E is in full support of City's promoting an increase in zero-emissions vehicle
travel by mandating electric vehicle charging infrastructure in a new residential and non-
residential buildings and existing new residential and non-residential buildings undergoing major
renovations. We also encourage the City identify additional ways to continue streamline
permitting for EV charging infrastructure across the board. There are numerous areas which
SDG&E can be a critical advisor/partner supporting the overall transition to transportation
electrification and we look forward to working with the City to install the infrastructure needed
to fulfill its clean transportation goals.
We are also proud to have over 6,900 Net Energy Metering solar customers in the City, whom
have invested in rooftop solar. We are encouraging our customers to go green by offering an
online application that makes the private solar rooftop interconnection process fast and
convenient for new solar adopters — it is one of fastest approval times in the state. Additionally,
SDG&E employees invented a Renewable Meter Adapter device which helps customers bypass
costly electric panel upgrades often needed to install private solar systems. This innovation,
combined with our fast track process, has helped close to 190,000 customers in the region to
install private solar equivalent of almoSt 1,000 MW of renewable generation capacity.
In closing, reaching the City's GHG emissions goals will require a host of thoughtful and
complementary efforts, including energy efficiency, clean energy, and clean transportation
programs. SDG&E plans to continue supporting the City in a comprehensive manner to meet our
mutual objective to improve the lives of those in our communities through a cleaner energy
future.
