Executive Summary
The purpose of this technical report is to assess the potential greenhouse gas (GHG) emissions impacts associated
with implementation of the proposed FPC Residential Project (Project). This assessment utilizes the significance
thresholds in Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 CCR 15000 et seq.).
Project Overview
The Project proposes to redevelop a 4.68-acre site with 86 residential units consisting of a combination of
rowhomes, townhomes, and triplexes, for a project density of 18.4 du/acre. The rowhomes and townhomes will be
3-story and the triplexes will be 2-story. The mix of units consists of eight 2-bedroom units, 40 3-bedroom units,
and 38 4-bedroom units. The Project will include 15% of the units (13) as affordable to low-income and will utilize
a density bonus, which would allow for up to 19.125du/ac. The Project will include 191 parking spaces with 2
internal per unit and 19 guest parking spaces.
Project Design Features
The proposed project would implement construction-related design features intended to reduce emissions of
criteria air pollutants and toxic air contaminants; the following measure would also be expected to reduce
construction-related GHG emissions.
PDF-AQ-1: Prior to the start of construction activities and issuance of grading permits, the project applicant,
or its designee, shall ensure that all 84 horsepower or greater diesel-powered equipment are
powered with California Air Resources Board (CARB)-certified Tier 4 Interim engines or better,
except where the project applicant establishes to the satisfaction of the City of San Diego (City) that
Tier 4 Interim equipment is not available.
An exemption from this requirement may be granted by the City if (1) the City documents equipment
with Tier 4 interim engines are not reasonably available, and (2) the required corresponding
reductions in criteria air pollutant emissions can be achieved for the project from other
combinations of construction equipment. Before an exemption may be granted, the construction
contractor shall: confirm that the proposed replacement equipment has been evaluated using
California Emissions Estimator Model (CalEEMod) or other industry standard emission estimation
method and documentation provided to the City to confirm that necessary project-generated
emissions reductions are achieved.
Although the proposed project’s GHG emissions are below the CAP Checklist screening level the following CAP
Checklist items are voluntarily proposes as project design features and would be expected to achieve additional
reductions to the project’s projected GHG emissions levels.
PDF-GHG-1 On-site photovoltaic systems which complies with CMC Section 18.30.130 and the 2019 California
Conde Section 150.1(c )14.

PDF-GHG-3 Electric Vehicle (EV) Charging which complies with CMC Section 18.21.140
PDFs would be required as City-imposed Conditions of Approval to ensure they are implemented during construction
and operation of the proposed project.
Greenhouse Gas Emissions
Global climate change is primarily considered a cumulative impact but must also be evaluated on a project-level
under CEQA. A project participates in this potential impact through its incremental contribution combined with the
cumulative increase of all other sources of GHG emissions. GHGs are gases that absorb infrared radiation in the
atmosphere. Principal GHGs regulated under state and federal law and regulations include carbon dioxide (CO2),
methane (CH4), and nitrous oxide (N2O). GHG emissions are measured in metric tons of CO2 equivalent (MT CO2e),
which account for weighted global warming potential (GWP) factors for CH4 and N2O.
Project Impacts
Construction of the Project would result in GHG emissions primarily associated with the use of off-road construction
equipment, on-road hauling and vendor (material delivery) trucks, and worker vehicles. The Project would generate
operational GHG emissions from area sources (landscape maintenance), energy sources (electricity consumption),
stationary source (lift station), mobile sources (vehicle trips), water supply and wastewater treatment, and solid
waste. Estimated annual Project-generated operational GHG emissions at buildout in 2025 would be approximately
806 MT CO2e per year. Estimated annual Project-generated operational emissions in 2025, plus amortized Project
construction emissions would be approximately 765 MT CO2e per year.
As discussed in Section 5, the Project operational emissions in 2025 plus amortized project construction emissions
would be less than the City’s CAP GHG threshold of 900 MT CO2e per year. As such, the Project would be consistent
with the CAP and would not be required to complete the CAP Checklist. The Project is consistent with the statewide
GHG reduction goals addressed in CARB’s 2008 and 2017 Scoping Plans and SANDAG’s 2021 Regional Plan. The
Project’s consistency stems from its location on an urban, infill site; its numerous design attributes that serve to
reduce natural gas consumption, promote building electrification, and achieve other efficiencies in the consumption
of energy, water and transportation fuels; and, its provision of residential opportunities (including affordable units)
in a jurisdiction with a jobs/housing ratio that evidences the need for more housing. Therefore, the Project would
be consistent with the statewide GHG reduction goals set forth in AB 32 and SB 32 and demonstrate progress
toward attaining the 2050 reduction goals within EO S-3-05. Impacts would be less than significant.

1 Introduction
1.1 Report Purpose and Scope
The purpose of this technical report is to assess the potential greenhouse gas (GHG) emissions impacts associated
with implementation of the proposed FPC Residential Project (Project). This assessment utilizes the significance
thresholds in Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 CCR 15000 et seq.).
This introductory section provides a description of the Project and the Project location. Section 2 describes existing
GHG-related conditions and Section 3 provides a summary of the regulatory setting. Section 4 presents the
thresholds of significance applied in the impact analysis contained in Section 5. Lastly, Section 6 includes a list of
the references cited.
1.2 Project Location
The approximate 4.68-acre Project site is located within the City of Carlsbad (City), California, San Diego County,
California. Specifically, the Project site is located at 7290 Ponto Drive in Carlsbad, California (City). The existing
project site consists of three parcels (APN’s: 214-160-25, 214-160-28, and 214-171-11) and is currently occupied
by a self-storage facility and junkyard. See Figure 1, and Figure 2.
The General Plan designation for the site is (R-15)/VC Q for two of the parcels, which represents residential
development with a density of 8 – 15 dwelling units (du) per acre (ac), and Visitor Commercial (VC) with a qualified
development overlay zone (Q); and R-15 for the third while the zoning of the site is Residential Density – Multiple
and Commercial Tourist (RD-M-Q/C-T) and Residential Density – Multiple with a qualified development overlay zone
(RD-M-Q) respectively. The proposed Project is consistent with both the General Plan designation and Zoning for
the property.
1.3 Project Description
The Project proposes to redevelop a 4.68-acre site with 86 multifamily residential units consisting of a combination
of rowhomes, townhomes, and triplexes, for a project density of 18.4 du/acre. The rowhomes and townhomes will
be 3-story and the triplexes will be 2-story. The mix of units consists of eight 2-bedroom units, 40 3-bedroom units,
and 38 4-bedroom units. The Project will include 15% of the units (13) as affordable to low-income households and
will utilize a density bonus, which would allow for up to 19.125du/ac.
The Project will include 191 parking spaces with 2 internal garage spaces per unit and 19 open-air guest parking
spaces.
Site improvements consist of an internal primary arterial street, dog park, and additional open space. Existing dry
utilities will be undergrounded and new water and stormwater connections will be made to existing facilities in
Ponto Drive. A private lift station will serve a new sewer connection north of the railroad tracks.
Off-site improvements consist of right of way dedication and construction of street, curb, and gutter along Ponto
Road and Ponto Drive.

2 Existing Conditions
2.1 Climate Change Overview
Climate change refers to any significant change in measures of climate, such as temperature, precipitation, or wind
patterns, lasting for an extended period of time (decades or longer). The Earth's temperature depends on the
balance between energy entering and leaving the planet’s system. Many factors, both natural and human, can
cause changes in Earth’s energy balance, including variations in the sun's energy reaching Earth, changes in the
reflectivity of Earth’s atmosphere and surface, and changes in the greenhouse effect, which affects the amount of
heat retained by Earth’s atmosphere (EPA 2017a).
The greenhouse effect is the trapping and build-up of heat in the atmosphere (troposphere) near the Earth’s
surface. 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 and emit it into space and
toward the Earth. The greenhouse effect is a natural process that contributes to regulating the Earth’s temperature
and creates a pleasant, livable environment on the Earth. Human activities that emit additional GHGs to the
atmosphere increase the amount of infrared radiation that gets absorbed before escaping into space, thus
enhancing the greenhouse effect and causing the Earth’s surface temperature to rise.
The scientific record of the Earth’s climate shows that the climate system varies naturally over a wide range of time
scales and that in general, climate changes prior to the Industrial Revolution in the 1700s can be explained by
natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in GHG concentrations.
Recent climate changes, in particular the warming observed over the past century, however, cannot be explained
by natural causes alone. Rather, it is extremely likely that human activities have been the dominant cause of that
warming since the mid-20th century and is the most significant driver of observed climate change (IPCC 2014; EPA
2017a). Human influence on the climate system is evident from the increasing GHG concentrations in the
atmosphere, positive radiative forcing, observed warming, and improved understanding of the climate system (IPCC
2014). The atmospheric concentrations of GHGs have increased to levels unprecedented in the last 800,000 years,
primarily from fossil fuel emissions and secondarily from emissions associated with land use changes (IPCC 2014).
Continued emissions of GHGs will cause further warming and changes in all components of the climate system,
which is discussed further in Section 2.5, Potential Effects of Climate Change.
2.2 Greenhouse Gases and other Climate
Forcing Substances
A GHG is any gas that absorbs infrared radiation in the atmosphere; in other words, GHGs trap heat in the
atmosphere. GHGs include, but are not limited to, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone
(O3), water vapor, hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and
sulfur hexafluoride (SF6).1 Some GHGs, such as CO2, CH4, and N2O, occur naturally and are emitted to the
atmosphere through natural processes and human activities. Of these gases, CO2 and CH4 are emitted in the
1 California Health and Safety Code 38505 identifies seven GHGs that CARB is responsible to monitor and regulate to reduce
emissions: CO2, CH4, N2O, SF6, HFCs, PFCs, and NF3.
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 9 JUNE 2022
greatest quantities from human activities. Manufactured GHGs, which have a much greater heat-absorption
potential than CO2, include fluorinated gases, such as HFCs, HCFCs, PFCs, and SF6, which are associated with
certain industrial products and processes. A summary of the most common GHGs and their sources is included in
the following text.2 Also included is a discussion of other climate forcing substances.
Carbon Dioxide (CO2). CO2 is a naturally occurring gas and a by-product of human activities and is the principal
anthropogenic GHG that affects the Earth’s radiative balance. Natural sources of CO2 include respiration of bacteria,
plants, animals, and fungus; evaporation from oceans; volcanic out-gassing; and decomposition of dead organic
matter. Human activities that generate CO2 are from the combustion of fuels such as coal, oil, natural gas, and
wood and changes in land use.
Methane (CH4). CH4 is produced through both natural and human activities. CH4 is a flammable gas and is the main
component of natural gas. Methane is produced through anaerobic (without oxygen) decomposition of waste in
landfills, flooded rice fields, animal digestion, decomposition of animal wastes, production and distribution of
natural gas and petroleum, coal production, and incomplete fossil fuel combustion.
Nitrous Oxide (N2O). N2O is produced through natural and human activities, mainly through agricultural activities
and natural biological processes, although fuel burning and other processes also create N2O. Sources of N2O
include soil cultivation practices (microbial processes in soil and water), especially the use of commercial and
organic fertilizers, manure management, industrial processes (such as in nitric acid production, nylon production,
and fossil-fuel-fired power plants), vehicle emissions, and using N2O as a propellant (such as in rockets, racecars,
and aerosol sprays).
Fluorinated Gases. Fluorinated gases (also referred to as F-gases) are synthetic powerful GHGs emitted from many
industrial processes. Fluorinated gases are commonly used as substitutes for stratospheric ozone-depleting
substances (e.g., CFCs, HCFCs, and halons). The most prevalent fluorinated gases include the following:
▪ Hydrofluorocarbons: HFCs are compounds containing only hydrogen, fluorine, and carbon atoms. HFCs are
synthetic chemicals used as alternatives to ozone-depleting substances in serving many industrial,
commercial, and personal needs. HFCs are emitted as by-products of industrial processes and are used in
manufacturing.
▪ Perfluorocarbons: PFCs are a group of human-made chemicals composed of carbon and fluorine only.
These chemicals were introduced as alternatives, with HFCs, to the ozone depleting substances. The two
main sources of PFCs are primary aluminum production and semiconductor manufacturing. Since PFCs
have stable molecular structures and do not break down through the chemical processes in the lower
atmosphere, these chemicals have long lifetimes, ranging between 10,000 and 50,000 years.
▪ Sulfur Hexafluoride: SF6 is a colorless gas soluble in alcohol and ether and slightly soluble in water. SF6 is
used for insulation in electric power transmission and distribution equipment, semiconductor
manufacturing, the magnesium industry, and as a tracer gas for leak detection.
▪ Nitrogen Trifluoride: NF3 is used in the manufacture of a variety of electronics, including semiconductors
and flat panel displays.
2 The descriptions of GHGs are summarized from the Intergovernmental Panel on Climate Change (IPCC) Second Assessment
Report (1995), IPCC Fourth Assessment Report (2007), CARB’s Glossary of Air Pollution Terms (2015), and EPA’s Glossary of
Climate Change Terms (2016).
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 10 JUNE 2022
Chlorofluorocarbons (CFCs). CFCs are synthetic chemicals that have been used as cleaning solvents, refrigerants,
and aerosol propellants. CFCs are chemically unreactive in the lower atmosphere (troposphere) and the production
of CFCs was prohibited in 1987 due to the chemical destruction of stratospheric O3.
Hydrochlorofluorocarbons (HCFCs). HCFCs are a large group of compounds, whose structure is very close to that of
CFCs—containing hydrogen, fluorine, chlorine, and carbon atoms—but including one or more hydrogen atoms. Like
HFCs, HCFCs are used in refrigerants and propellants. HCFCs were also used in place of CFCs for some applications;
however, their use in general is being phased out.
Black Carbon. Black carbon is a component of fine particulate matter, which has been identified as a leading
environmental risk factor for premature death. It is produced from the incomplete combustion of fossil fuels and
biomass burning, particularly from older diesel engines and forest fires. Black carbon warms the atmosphere by
absorbing solar radiation, influences cloud formation, and darkens the surface of snow and ice, which accelerates
heat absorption and melting. Black carbon is a short-lived species that varies spatially, which makes it difficult to
quantify the global warming potential. Diesel particulate matter emissions are a major source of black carbon and
are toxic air contaminates (TACs) that have been regulated and controlled in California for several decades to
protect public health. In relation to declining diesel particulate matter from the California Air Resources Board’s
(CARB’s) regulations pertaining to diesel engines, diesel fuels, and burning activities, CARB estimates that annual
black carbon emissions in California have reduced by 70% between 1990 and 2010, with 95% control expected by
2020 (CARB 2014a).
Water Vapor. The primary source of water vapor is evaporation from the ocean, with additional vapor generated by
sublimation (change from solid to gas) from ice and snow, evaporation from other water bodies, and transpiration
from plant leaves. Water vapor is the most important, abundant, and variable GHG in the atmosphere and maintains
a climate necessary for life.
Ozone (O3). Tropospheric O3, which is created by photochemical reactions involving gases from both natural
sources and human activities, acts as a GHG. Stratospheric O3, which is created by the interaction between solar
ultraviolet radiation and molecular oxygen (O2), plays a decisive role in the stratospheric radiative balance.
Depletion of stratospheric O3, due to chemical reactions that may be enhanced by climate change, results in an
increased ground-level flux of ultraviolet-B radiation.
Aerosols. Aerosols are suspensions of particulate matter in a gas emitted into the air through burning biomass
(plant material) and fossil fuels. Aerosols can warm the atmosphere by absorbing and emitting heat and can cool
the atmosphere by reflecting light.
2.3 Global Warming Potential
Gases in the atmosphere can contribute to climate change both directly and indirectly. Direct effects occur when
the gas itself absorbs radiation. Indirect radiative forcing occurs when chemical transformations of the substance
produce other GHGs, when a gas influences the atmospheric lifetimes of other gases, and/or when a gas affects
atmospheric processes that alter the radiative balance of the Earth (e.g., affect cloud formation or albedo) (EPA
2017a). The Intergovernmental Panel on Climate Change (IPCC) developed the global warming potential (GWP)
concept to compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP of a
GHG is defined as the ratio of the time-integrated radiative forcing from the instantaneous release of 1 kilogram of
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 11 JUNE 2022
a trace substance relative to that of 1 kilogram of a reference gas (IPCC 2014). The reference gas used is CO2;
therefore, GWP-weighted emissions are measured in MT CO2 equivalent (CO2e).
The current version of the California Emissions Estimator Model (CalEEMod) (version 2020.4.0) assumes that the
GWP for CH4 is 25 (so emissions of 1 MT of CH4 are equivalent to emissions of 25 MT of CO2), and the GWP for N2O
is 298, based on the IPCC Fourth Assessment Report (IPCC 2007). The GWP values identified in CalEEMod were
applied to the Project.
2.4 Sources of Greenhouse Gas Emissions
Global Inventory
Anthropogenic GHG emissions worldwide in 2017 (the most recent year for which data is available) totaled
approximately 50,860 MMT of CO2e, excluding land use change and forestry (Olivier and Peters 2018). Six
countries—China, the United States, the Russian Federation, India, Japan, and Brazil—and the European community
accounted for approximately 65% of the total global emissions, or approximately 33,290 MMT CO2e (Olivier and
Peters 2018). Table 1 presents the top GHG-emissions-producing countries, as well as the European Union.

National, State, and Local Inventories
Per the 2019 EPA Inventory of U.S. GHG Emissions and Sinks: 1990–2017, total U.S. GHG emissions were
approximately 6,457 MMT CO2e in 2017 (EPA 2019). The primary GHG emitted by human activities in the United
States was CO2, which represented approximately 81.6% of total GHG emissions (6,457 MMT CO2e). The largest
source of CO2, and of overall GHG emissions, was fossil-fuel combustion, which accounted for approximately 93.2%
of CO2 emissions in 2017 (4,912.0 MMT CO2e). Relative to the 1990 emissions level, gross U.S. GHG emissions in
2017 were 1.3% higher; however, the gross emissions were down from a high of 15.7% above the 1990 level that
occurred in 2007. GHG emissions decreased from 2016 to 2017 by 0.5% (35.5 MMT CO2e) and, overall, net
emissions in 2017 were 13% below 2005 levels (EPA 2019).
According to California’s 2000–2018 GHG emissions inventory (2020 edition), California emitted 425 MMT CO2e
in 2018, including emissions resulting from out-of-state electrical generation (CARB 2020c). The sources of GHG
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS

emissions in California include transportation, industry, electric power production from both in-state and out-of-
state sources, residential and commercial activities, agriculture, high GWP substances, and recycling and waste.
The California GHG emission source categories and their relative contributions in 2018 are presented in Table 2,

Between 2000 and 2018, per-capita GHG emissions in California have dropped from a peak of 14.0 MT per person
in 2001 to 10.7 MT per person in 2018, representing a 24% decrease. In addition, total GHG emissions in 2018
were approximately 0.8 MMT CO2e less than 2017 emissions (CARB 2020c).
According to the GHG inventory data compiled by the Energy Policy Initiative Center, in 2010, the County (as defined
to include all cities therein and unincorporated County areas) emitted 34.7 MMT CO2e (EPIC 2015). As outlined in
Table 3, San Diego County GHG Emissions by Sectors, on-road transportation created 37% of these emissions.
Similar to emissions trends statewide, electricity generation is the second biggest emitter.

2.5 Potential Effects of Human Activity on Climate
Change
Globally, climate change has the potential to affect numerous environmental resources through uncertain impacts
related to future air temperatures and precipitation patterns. The 2014 Intergovernmental Panel on Climate Change
Synthesis Report indicated that warming of the climate system is unequivocal and since the 1950s, many of the
observed changes are unprecedented over decades to millennia. Signs that global climate change has occurred
include warming of the atmosphere and ocean, diminished amounts of snow and ice, and rising sea levels
(IPCC 2014).
In California, climate change impacts have the potential to affect sea level rise, agriculture, snowpack and water
supply, forestry, wildfire risk, public health, and electricity demand and supply. The primary effect of global climate
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 14 JUNE 2022
change has been a 0.2°C rise in average global tropospheric temperature per decade, determined from
meteorological measurements worldwide between 1990 and 2005. Scientific modeling predicts that continued
emissions of GHGs at or above current rates would induce more extreme climate changes during the twenty-first
century than were observed during the twentieth century. A warming of about 0.2°C (0.36°F) per decade is
projected, and there are identifiable signs that global warming could be taking place.
Although climate change is driven by global atmospheric conditions, climate change impacts are felt locally. A
scientific consensus confirms that climate change is already affecting California. The average temperatures in
California have increased, leading to more extreme hot days and fewer cold nights; shifts in the water cycle have
been observed, with less winter precipitation falling as snow, and both snowmelt and rainwater running off earlier
in the year; sea levels have risen; and wildland fires are becoming more frequent and intense due to dry seasons
that start earlier and end later (CAT 2010).
An increase in annual average temperature is a reasonably foreseeable effect of climate change. Observed changes
over the last several decades across the western United States reveal clear signals of climate change. Statewide
average temperatures increased by about 1.7°F from 1895 to 2011, and warming has been greatest in the Sierra
Nevada. By 2050, California is projected to warm by approximately 2.7°F above 2000 averages, a threefold
increase in the rate of warming over the last century. By 2100, average temperatures could increase by 4.1°F to
8.6°F, depending on emissions levels. Springtime warming—a critical influence on snowmelt—will be particularly
pronounced. Summer temperatures will rise more than winter temperatures, and the increases will be greater in
inland California, compared to the coast. Heat waves will be more frequent, hotter, and longer. There will be fewer
extremely cold nights. A decline of Sierra snowpack, which accounts for approximately half of the surface water
storage in California and much of the State’s water supply, by 30% to as much as 90% is predicted over the next
100 years (CAT 2010).
Model projections for precipitation over California continue to show the Mediterranean pattern of wet winters and
dry summers with seasonal, year-to-year, and decade-to-decade variability. For the first time, however, several of
the improved climate models shift toward drier conditions by the mid-to-late 21st century in Central and, most
notably, Southern California. By late-century, all projections show drying, and half of them suggest 30-year average
precipitation will decline by more than 10% below the historical average (CAT 2010).
A summary of current and future climate change impacts to resource areas in California, as discussed in the
Safeguarding California: Reducing Climate Risk (CNRA 2014), is provided in the following text.
Agriculture. The impacts of climate change on the agricultural sector are far more severe than the typical variability
in weather and precipitation patterns that occur year to year. Some of the specific challenges faced by the
agricultural sector and farmers include more drastic and unpredictable precipitation and weather patterns; extreme
weather events that range from severe flooding to extreme drought, to destructive storm events; significant shifts
in water availably and water quality; changes in pollinator lifecycles; temperature fluctuations, including extreme
heat stress and decreased chill hours; increased risks from invasive species and weeds, agricultural pests and
plant diseases; and disruptions to the transportation and energy infrastructure supporting agricultural production.
These challenges and associated short-term and long-term impacts can have both positive and negative effects on
agricultural production. Nonetheless, it is predicted that current crop and livestock production will suffer long-term
negative effects resulting in a substantial decrease in the agricultural sector if not managed or mitigated.

14183 15 JUNE 2022
Biodiversity and Habitat. The state’s extensive biodiversity stems from its varied climate and assorted landscapes,
which have resulted in numerous habitats where species have evolved and adapted over time. Specific climate
change challenges to biodiversity and habitat include species migration in response to climatic changes, range
shift, and novel combinations of species; pathogens, parasites and disease; invasive species; extinction risks;
changes in the timing of seasonal life-cycle events; food web disruptions; and threshold effects (i.e., a change in
the ecosystem that results in a “tipping point” beyond which irreversible damage or loss has occurs). Habitat
restoration, conservation, and resource management across California and through collaborative efforts amongst
public, private and nonprofit agencies has assisted in the effort to fight climate change impacts on biodiversity and
habitat. One of the key measures in these efforts is ensuring species’ ability to relocate as temperature and water
availability fluctuate as a result of climate change, based on geographic region.
Energy. The energy sector provides California residents with a supply of reliable and affordable energy through a
complex integrated system. Specific climate change challenges for the energy sector include temperature,
fluctuating precipitation patterns, increasing extreme weather events and sea level rise. Increasing temperatures
and reduced snowpack negatively impact the availability of a steady flow of snowmelt to hydroelectric reservoirs.
Higher temperatures also reduce the capacity of thermal power plants since power plant cooling is less efficient at
higher ambient temperatures. Natural gas infrastructure in coastal California is threatened by sea level rise and
extreme storm events.
Forestry. Forests occupy approximately 33% of California’s 100 million acres and provide key benefits such as
wildlife habitat, absorption of CO2, renewable energy and building materials. The most significant climate change
related risk to forests is accelerated risk of wildfire and more frequent and severe droughts. Droughts have resulted
in more large scale mortalities and combined with increasing temperatures have led to an overall increase in wildfire
risks. Increased wildfire intensity subsequently increases public safety risks, property damage, fire suppression and
emergency response costs, watershed and water quality impacts and vegetation conversions. These factors
contribute to decreased forest growth, geographic shifts in tree distribution, loss of fish and wildlife habitat and
decreased carbon absorption. Climate change may result in increased establishment of non-native species,
particularly in rangelands where invasive species are already a problem. Invasive species may be able to exploit
temperature or precipitation changes, or quickly occupy areas denuded by fire, insect mortality or other climate
change effects on vegetation.
Ocean and Coastal Ecosystems and Resources. Sea level rise, changing ocean conditions and other climate change
stressors are likely to exacerbate long-standing challenges related to ocean and coastal ecosystems in addition to
threatening people and infrastructure located along the California coastline and in coastal communities. Sea level
rise in addition to more frequent and severe coastal storms and erosion are threatening vital infrastructure such as
roads, bridges, power plants, ports and airports, gasoline pipes, and emergency facilities, as well as negatively
impacting the coastal recreational assets such as beaches and tidal wetlands. Water quality and ocean acidification
threaten the abundance of seafood and other plant and wildlife habitats throughout California and globally.
Public Health. Climate change can impact public health through various environmental changes and is the largest
threat to human health in the twenty-first century. Changes in precipitation patterns affect public health primarily
through potential for altered water supplies, and extreme events such as heat, floods, droughts, and wildfires.
Increased frequency, intensity and duration of extreme heat and heat waves is likely to increase the risk of mortality
due to heat related illness as well as exacerbate existing chronic health conditions. Other extreme weather events
are likely to negatively impact air quality and increase or intensify respiratory illness such as asthma and allergies.
Additional health impacts that may be impacted by climate change include cardiovascular disease, vector-borne
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 16 JUNE 2022
diseases, mental health impacts, and malnutrition injuries. Increased frequency of these ailments is likely to
subsequently increase the direct risk of injury and/or mortality.
Transportation. Residents of California rely on airports, seaports, public transportation and an extensive roadway
network to gain access to destinations, goods and services. While the transportation industry is a source of GHG
emissions it is also vulnerable to climate change risks. Particularly, sea level rise and erosion threaten many coastal
California roadways, airports, seaports, transit systems, bridge supports, and energy and fueling infrastructure.
Increasing temperatures and extended periods of extreme heat threaten the integrity of the roadways and rail lines.
High temperatures cause the road surfaces to expand which leads to increased pressure and pavement buckling.
High temperatures can also cause rail breakages, which could lead to train derailment. Other forms of extreme
weather events, such as extreme storm events, can negatively impact infrastructure which can impair movement
of peoples and goods, or potentially block evacuation routes and emergency access roads. Increased wildfires,
flooding, erosion risks, landslides, mudslides, and rockslides can all profoundly impact the transportation system
and pose a serious risk to public safety.
Water. Water resources in California support residences, plants, wildlife, farmland, landscapes and ecosystems and
bring trillions of dollars in economic activity. Climate change could seriously impact the timing, form, amount of
precipitation, runoff patterns, and frequency and severity of precipitation events. Higher temperatures reduce the
amount of snowpack and lead to earlier snowmelt, which can impact water supply availability, natural ecosystems
and winter recreation. Water supply availability during the intense dry summer months is heavily dependent on the
snowpack accumulated during the winter time. Increased risk of flooding has a variety of public health concerns
including water quality, public safety, property damage, displacement and post-disaster mental health problems.
Prolonged and intensified droughts can also negatively groundwater reserves and result in increased overdraft and
subsidence. Droughts can also negatively impact agriculture and farmland throughout the state. The higher risk of
wildfires can lead to increased erosion, which can negatively impact watersheds and result in poor water quality.
Water temperatures are also prone to increase, which can negatively impact wildlife that rely on a specific range of
temperatures for suitable habitat.

3 Regulatory Setting
3.1 Federal
Massachusetts v. EPA. In Massachusetts v. EPA (April 2007), the U.S. Supreme Court directed the EPA administrator
to determine whether GHG emissions from new motor vehicles cause or contribute to air pollution that may
reasonably be anticipated to endanger public health or welfare, or whether the science is too uncertain to make a
reasoned decision. In December 2009, the administrator signed a final rule with the following two distinct findings
regarding GHGs under Section 202(a) of the federal Clean Air Act:
▪ The Administrator found that elevated concentrations of GHGs—CO2, CH4, N2O, HFCs, PFCs, and SF6—in the
atmosphere threaten the public health and welfare of current and future generations. This is the
“endangerment finding.”
▪ The Administrator further found the combined emissions of GHGs—CO2, CH4, N2O, and HFCs—from new motor
vehicles and new motor vehicle engines contribute to the GHG air pollution that endangers public health and
welfare. This is the “cause or contribute finding.”
These two findings were necessary to establish the foundation for regulation of GHGs from new motor vehicles as
air pollutants under the Clean Air Act.
Energy Independence and Security Act of 2007. The Energy Independence and Security Act of 2007
(December 2007), among other key measures, would do the following, which would aid in the reduction of national
GHG emissions (EPA 2007):
▪ Increase the supply of alternative fuel sources by setting a mandatory Renewable Fuel Standard requiring
fuel producers to use at least 36 billion gallons of biofuel in 2022.
▪ Set a target of 35 miles per gallon for the combined fleet of cars and light trucks by model year 2020, and
directs National Highway Traffic Safety Administration (NHTSA) to establish a fuel economy program for
medium- and heavy-duty trucks and create a separate fuel economy standard for work trucks.
▪ Prescribe or revise standards affecting regional efficiency for heating and cooling products and procedures
for new or amended standards, energy conservation, energy-efficiency labeling for consumer electronic
products, residential boiler efficiency, electric motor efficiency, and home appliances.
Federal Vehicle Standards. In response to the U.S. Supreme Court ruling discussed above, the Bush Administration
issued Executive Order (EO) 13432 in 2007 directing the EPA, the Department of Transportation, and the
Department of Energy to establish regulations that reduce GHG emissions from motor vehicles, non-road vehicles,
and non-road engines by 2008. In 2009, the NHTSA issued a final rule regulating fuel efficiency and GHG emissions
from cars and light-duty trucks for model year 2011, and in 2010, the EPA and NHTSA issued a final rule regulating
cars and light-duty trucks for model years 2012–2016 (EPA 2010).
In 2010, President Barack Obama issued a memorandum directing the Department of Transportation, Department
of Energy, EPA, and NHTSA to establish additional standards regarding fuel efficiency and GHG reduction, clean
fuels, and advanced vehicle infrastructure. In response to this directive, EPA and NHTSA proposed stringent,
coordinated federal GHG and fuel economy standards for model years 2017–2025 light-duty vehicles. The
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 19 JUNE 2022
proposed standards projected to achieve 163 grams per mile of CO2 in model year 2025, on an average industry
fleet-wide basis, which is equivalent to 54.5 miles per gallon if this level were achieved solely through fuel efficiency.
The final rule was adopted in 2012 for model years 2017–2021.
In addition to the regulations applicable to cars and light-duty trucks described above, in 2011, the EPA and NHTSA
announced fuel economy and GHG standards for medium- and heavy-duty trucks for model years 2014–2018. The
standards for CO2 emissions and fuel consumption are tailored to three main vehicle categories: combination
tractors, heavy-duty pickup trucks and vans, and vocational vehicles. According to the EPA, this regulatory program
will reduce GHG emissions and fuel consumption for the affected vehicles by 6%–23% over the 2010 baselines.
In August 2016, the EPA and NHTSA announced the adoption of the phase two program related to the fuel economy
and GHG standards for medium- and heavy-duty trucks. The phase two program will apply to vehicles with model
year 2018 through 2027 for certain trailers, and model years 2021 through 2027 for semi-trucks, large pickup
trucks, vans, and all types and sizes of buses and work trucks. The final standards are expected to lower CO2
emissions by approximately 1.1 billion MT and reduce oil consumption by up to 2 billion barrels over the lifetime of
the vehicles sold under the program (EPA and NHTSA 2016).
On September 19, 2019, the NHTSA and the EPA issued a final action entitled the “One National Program Rule” to
enable the federal government to provide nationwide uniform fuel economy and greenhouse gas emission
standards for automobile and light-duty trucks (EPA 2019). This action finalizes critical parts of the Safer,
Affordable, Fuel-Efficient (SAFE) Vehicles Rule that was first proposed in August 2018. This action makes clear that
federal law preempts state and local tailpipe GHG emissions standards as well as zero emission vehicle (ZEV)
mandates. California and other states have challenged federal actions that would delay or eliminate GHG reduction
measures and have committed to cooperating with other countries to implement global climate change initiatives.
The timing and consequences of these types of federal decisions and subsequent challenges are speculative at
this time (CARB 2019a). Relatedly, CARB has not determined at this time what impacts the SAFE rule may have on
GHG emissions.
3.2 State
The statewide GHG emissions regulatory framework is summarized below by category: state climate change targets,
building energy, renewable energy and energy procurement, mobile sources, solid waste, water, and other state
regulations and goals. The following text describes executive orders, legislation, regulations, and other plans and
policies that would directly or indirectly reduce GHG emissions and/or address climate change issues.
State Climate Change Targets
Executive Order (EO) S-3-05. EO S-3-05 (June 2005) established the following statewide goals: GHG emissions
should be reduced to 2000 levels by 2010, GHG emissions should be reduced to 1990 levels by 2020, and GHG
emissions should be reduced to 80% below 1990 levels by 2050.
Assembly Bill (AB) 32 and CARB’s Climate Change Scoping Plan. In furtherance of the goals established in EO S-3-
05, the Legislature enacted AB 32, the California Global Warming Solutions Act of 2006. AB 32 requires California
to reduce its GHG emissions to 1990 levels by 2020.
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 20 JUNE 2022
Under AB 32, CARB is responsible for and is recognized as having the expertise to carry out and develop the
programs and requirements necessary to achieve the GHG emissions reduction mandate of AB 32. Under AB 32,
CARB must adopt regulations requiring the reporting and verification of statewide GHG emissions from specified
sources. This program is used to monitor and enforce compliance with established standards. CARB also is required
to adopt rules and regulations to achieve the maximum technologically feasible and cost-effective GHG emission
reductions. AB 32 relatedly authorized CARB to adopt market-based compliance mechanisms to meet the specified
requirements. Finally, CARB is ultimately responsible for monitoring compliance and enforcing any rule, regulation,
order, emission limitation, emission reduction measure, or market-based compliance mechanism adopted.
In 2007, CARB approved a limit on the statewide GHG emissions level for year 2020 consistent with the determined
1990 baseline (427 MMT CO2e). CARB’s adoption of this limit is in accordance with Health and Safety Code
Section 38550.
Further, in 2008, CARB adopted the Climate Change Scoping Plan: A Framework for Change (Scoping Plan) in
accordance with Health and Safety Code Section 38561. The Scoping Plan establishes an overall framework for
the measures that will be adopted to reduce California’s GHG emissions for various emission sources/sectors to
1990 levels by 2020. The Scoping Plan evaluates opportunities for sector-specific reductions, integrates all CARB
and Climate Action Team early actions and additional GHG reduction features by both entities, identifies additional
measures to be pursued as regulations, and outlines the role of a cap-and-trade program. The key elements of the
Scoping Plan include the following (CARB 2008):
1. Expanding and strengthening existing energy efficiency programs as well as building and appliance standards
2. Achieving a statewide renewable energy mix of 33%
3. Developing a California cap-and-trade program that links with other Western Climate Initiative partner programs
to create a regional market system and caps sources contributing 85% of California’s GHG emissions
4. Establishing targets for transportation-related GHG emissions for regions throughout California, and
pursuing policies and incentives to achieve those targets
5. Adopting and implementing measures pursuant to existing state laws and policies, including California’s
clean car standards, goods movement measures, and the Low Carbon Fuel Standard
6. Creating targeted fees, including a public goods charge on water use, fees on high GWP gases, and a fee
to fund the administrative costs of the State of California’s long-term commitment to AB 32 implementation
In the Scoping Plan, CARB determined that achieving the 1990 emissions level in 2020 would require a reduction
in GHG emissions of approximately 28.5% from the otherwise projected 2020 emissions level; i.e., those emissions
that would occur in 2020, absent GHG-reducing laws and regulations (referred to as “Business-As-Usual” [BAU]).
For purposes of calculating this percent reduction, CARB assumed that all new electricity generation would be
supplied by natural gas plants, no further regulatory action would impact vehicle fuel efficiency, and building energy
efficiency codes would be held at 2005 standards.
In the 2011 Final Supplement to the Scoping Plan’s Functional Equivalent Document, CARB revised its estimates
of the projected 2020 emissions level in light of the economic recession and the availability of updated information
about GHG reduction regulations. Based on the new economic data, CARB determined that achieving the 1990
emissions level by 2020 would require a reduction in GHG emissions of 21.7% (down from 28.5%) from the BAU
conditions. When the 2020 emissions level projection also was updated to account for newly implemented
regulatory measures, including Pavley I (model years 2009–2016) and the Renewable Portfolio Standard (12% to
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 21 JUNE 2022
20%), CARB determined that achieving the 1990 emissions level in 2020 would require a reduction in GHG
emissions of 16% (down from 28.5%) from the BAU conditions.
In 2014, CARB adopted the First Update to the Climate Change Scoping Plan: Building on the Framework (First
Update). The stated purpose of the First Update is to “highlight California’s success to date in reducing its GHG
emissions and lay the foundation for establishing a broad framework for continued emission reductions beyond
2020, on the path to 80% below 1990 levels by 2050” (CARB 2014b). The First Update found that California is on
track to meet the 2020 emissions reduction mandate established by AB 32, and noted that California could reduce
emissions further by 2030 to levels squarely in line with those needed to stay on track to reduce emissions to 80%
below 1990 levels by 2050 if the state realizes the expected benefits of existing policy goals.
In conjunction with the First Update, CARB (2014b) identified “six key focus areas comprising major components
of the state’s economy to evaluate and describe the larger transformative actions that will be needed to meet the
state’s more expansive emission reduction needs by 2050.” Those six areas are: (1) energy; (2) transportation
(vehicles/equipment, sustainable communities, housing, fuels, and infrastructure); (3) agriculture; (4) water; (5)
waste management; and, (6) natural and working lands. The First Update identifies key recommended actions for
each sector that will facilitate achievement of EO S-3-05’s 2050 reduction goal.
Based on CARB’s research efforts presented in the First Update, it has a “strong sense of the mix of technologies
needed to reduce emissions through 2050.” Those technologies include energy demand reduction through
efficiency and activity changes; large-scale electrification of on-road vehicles, buildings and industrial machinery;
decarbonizing electricity and fuel supplies; and, the rapid market penetration of efficient and clean energy
technologies (CARB 2014b).
As part of the First Update, CARB (2014b) recalculated the state’s 1990 emissions level using more recent global
warming potentials identified by the IPCC. Using the recalculated 1990 emissions level (431 MMT CO2e) and the
revised 2020 emissions level projection identified in the 2011 Final Supplement, CARB determined that achieving
the 1990 emissions level by 2020 would require a reduction in GHG emissions of approximately 15% (instead of
28.5% or 16%) from the BAU conditions.
In December 2017, CARB adopted California’s 2017 Climate Change Scoping Plan (2017 Scoping Plan) (CARB
2017b). This plan outlines CARB’s strategy for achieving the state’s 2030 GHG target as established in Senate Bill
(SB) 32 (discussed below), including continuing the Cap-and-Trade Program through 2030. The 2017 Scoping Plan
incorporates approaches to cutting short-lived climate pollutants (SLCPs) under the Short-Lived Climate Pollutant
Reduction Strategy (a planning document that was adopted by CARB in March 2017) and acknowledges the need
for reducing emissions in agriculture and highlights the work underway to ensure that California’s natural and
working lands increasingly sequester carbon. During development of the 2017 Scoping Plan, CARB held a number
of public workshops in the Natural and Working Lands, Agriculture, Energy, and Transportation sectors to inform
development of the 2030 Scoping Plan Update (CARB 2017b).
The Scoping Plan recommends strategies for implementation at the statewide level to meet the goals of AB 32, SB
32 and the Executive Orders and establishes an overall framework for the measures that will be adopted to reduce
California’s GHG emissions. A project is considered consistent with the statutes and Executive Orders if it meets
the general policies in reducing GHG emissions in order to facilitate the achievement of the state’s goals and does
not impede attainment of those goals. As discussed in several cases, a given project need not be in perfect
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 22 JUNE 2022
conformity with each and every planning policy or goals to be consistent. A project would be consistent, if it will
further the objectives and not obstruct their attainment.
EO B-30-15. EO B-30-15 (April 2015) identified an interim GHG reduction target in support of targets previously
identified under EO S-3-05 and AB 32. EO B-30-15 set an interim target goal of reducing statewide GHG emissions
to 40% below 1990 levels by 2030 to keep California on its trajectory toward meeting or exceeding the long-term
goal of reducing statewide GHG emissions to 80% below 1990 levels by 2050 as set forth in EO S-3-05. To facilitate
achievement of this goal, EO B-30-15 calls for an update to CARB’s Scoping Plan to express the 2030 target in
terms of MMT CO2e. The EO also calls for state agencies to continue to develop and implement GHG emission
reduction programs in support of the reduction targets. Sector-specific agencies in transportation, energy, water,
and forestry were required to prepare GHG reduction plans by September 2015, followed by a report on action
taken in relation to these plans in June 2016. EO B-30-15 does not require local agencies to take any action to
meet the new interim GHG reduction target.
SB 32 and AB 197. SB 32 and AB 197 (enacted in 2016) are companion bills that set a new statewide GHG
reduction targets; make changes to CARB’s membership, and increase legislative oversight of CARB’s climate
change-based activities; and expand dissemination of GHG and other air quality-related emissions data to enhance
transparency and accountability. More specifically, SB 32 codified the 2030 emissions reduction goal of EO B-30-
15 by requiring CARB to ensure that statewide GHG emissions are reduced to 40% below 1990 levels by 2030. AB
197 established the Joint Legislative Committee on Climate Change Policies, consisting of at least three members
of the Senate and three members of the Assembly, in order to provide ongoing oversight over implementation of
the state’s climate policies. AB 197 also added two members of the Legislature to CARB as nonvoting members;
requires CARB to make available and update (at least annually via its website) emissions data for GHGs, criteria air
pollutants, and TACs from reporting facilities; and, requires CARB to identify specific information for GHG emissions
reduction measures when updating the scoping plan.
SB 605 and SB 1383. SB 605 (2014) requires CARB to complete a comprehensive strategy to reduce emissions
of short-lived climate pollutants in the state; and SB 1383 (2016) requires CARB to approve and implement that
strategy by January 1, 2018. SB 1383 also establishes specific targets for the reduction of SLCPs (40% below 2013
levels by 2030 for methane and HFCs, and 50% below 2013 levels by 2030 for anthropogenic black carbon), and
provides direction for reductions from dairy and livestock operations and landfills. Accordingly, and as mentioned
above, CARB adopted its Short-Lived Climate Pollutant Reduction Strategy (SLCP Reduction Strategy) in March
2017. The SLCP Reduction Strategy establishes a framework for the statewide reduction of emissions of black
carbon, methane and fluorinated gases.
EO B-55-18 (September 2018) established a new statewide goal “to achieve carbon neutrality as soon as possible,
and no later than 2045, and achieve and maintain net negative emissions thereafter.” This executive order directed
CARB to “work with relevant state agencies to ensure future Scoping Plans identify and recommend measures to
achieve the carbon neutrality goal.”
Building Energy
The 2019 Title 24 standards are the currently applicable building energy efficiency standards, and became effective
on January 1, 2020.
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS

Title 24, Part 6. Title 24 of the California Code of Regulations was established in 1978 and serves to enhance and
regulate California’s building standards. While not initially promulgated to reduce GHG emissions, Part 6 of Title 24
specifically establishes Building Energy Efficiency Standards that are designed to ensure new and existing buildings
in California achieve energy efficiency and preserve outdoor and indoor environmental quality. The California Energy
Commission (CEC) is required by law to adopt standards every 3 years that are cost effective for homeowners over
the 30-year lifespan of a building. These standards are updated to consider and incorporate new energy efficient
technologies and construction methods. As a result, these standards save energy, increase electricity supply
reliability, increase indoor comfort, avoid the need to construct new power plants, and help preserve the
environment. As an example, single-family residences built to the 2019 standards are anticipated to use
approximately 7% less energy due to energy efficiency measures than those built to the 2016 standards; once
rooftop solar electricity generation is factored in, single-family residences built under the 2019 standards will use
approximately 53% less energy than those under the 2016 standards (CEC 2018a). Nonresidential buildings built
to the 2019 standards are anticipated to use an estimated 30% less energy than those built to the 2016 standards
(CEC 2018a).
Title 24, Part 11. In addition to the CEC’s efforts, in 2008, the California Building Standards Commission adopted
the nation’s first green building standards. The California Green Building Standards Code (Part 11 of Title 24) is
commonly referred to as California’s Green Building Standards (CALGreen), and establishes minimum mandatory
standards and voluntary standards pertaining to the planning and design of sustainable site development, energy
efficiency (in excess of the California Energy Code requirements), water conservation, material conservation, and
interior air quality. The CALGreen standards took effect in January 2011 and instituted mandatory minimum
environmental performance standards for all ground-up, new construction of commercial, low-rise residential and
state-owned buildings, schools, and hospitals. The CALGreen 2019 standards, which are the current standards,
became effective January 1, 2020.
Title 20. Title 20 of the California Code of Regulations requires manufacturers of appliances to meet state and
federal standards for energy and water efficiency. Performance of appliances must be certified through the CEC to
demonstrate compliance with standards. New appliances regulated under Title 20 include: refrigerators,
refrigerator-freezers and freezers; room air conditioners and room air-conditioning heat pumps; central air
conditioners; spot air conditioners; vented gas space heaters; gas pool heaters; plumbing fittings and plumbing
fixtures; fluorescent lamp ballasts; lamps; emergency lighting; traffic signal modules; dishwaters; clothes washers
and dryers; cooking products; electric motors; low voltage dry-type distribution transformers; power supplies;
televisions and consumer audio and video equipment; and battery charger systems. Title 20 presents protocols for
testing for each type of appliance covered under the regulations and appliances must meet the standards for energy
performance, energy design, water performance and water design. Title 20 contains three types of standards for
appliances: federal and state standards for federally regulated appliances, state standards for federally regulated
appliances, and state standards for non-federally regulated appliances.
SB 1. SB 1 (2006) established a $3 billion rebate program to support the goal of the state to install rooftop solar
energy systems with a generation capacity of 3,000 megawatts through 2016. SB 1 added sections to the Public
Resources Code, including Chapter 8.8 (California Solar Initiative), which require building projects applying for
ratepayer-funded incentives for photovoltaic systems to meet minimum energy efficiency levels and performance
requirements. Section 25780 established that it is a goal of the state to establish a self-sufficient solar industry in
which solar energy systems are a viable mainstream option for both homes and businesses within 10 years of
adoption, and to place solar energy systems on 50% of new homes within 13 years of adoption. SB 1, also termed
“GoSolarCalifornia,” was previously titled “Million Solar Roofs.”

AB 1470. This bill established the Solar Water Heating and Efficiency Act of 2007. The bill makes findings and
declarations of the Legislature relating to the promotion of solar water heating systems and other technologies that
reduce natural gas demand. The bill defines several terms for purposes of the act. The bill requires the commission
to evaluate the data available from a specified pilot program, and, if it makes a specified determination, to design
and implement a program of incentives for the installation of 200,000 solar water heating systems in homes and
businesses throughout the state by 2017.
AB 1109. Enacted in 2007, AB 1109 required the CEC to adopt minimum energy efficiency standards for general
purpose lighting, to reduce electricity consumption 50% for indoor residential lighting and 25% for indoor
commercial lighting.
California AB 1470 (Solar Water Heating). This bill established the Solar Water Heating and Efficiency Act of 2007.
AB 1470 makes findings and declarations of the Legislature relating to the promotion of solar water heating
systems and other technologies that reduce natural gas demand. AB 1470 defines several terms for purposes of
the act. The bill required a commission to evaluate the data available from a specified pilot program, and to design
and implement a program of incentives for the installation of 200,000 solar water heating systems in homes and
businesses throughout the state by 2017.
Renewable Energy and Energy Procurement
SB 1078. SB 1078 (2002) established the Renewable Portfolio Standard (RPS) program, which requires an annual
increase in renewable generation by the utilities equivalent to at least 1% of sales, with an aggregate goal of 20%
by 2017. This goal was subsequently accelerated, requiring utilities to obtain 20% of their power from renewable
sources by 2010.
SB 1368. SB 1368 (2006) requires the CEC to develop and adopt regulations for GHG emission performance
standards for the long-term procurement of electricity by local publicly owned utilities. These standards must be
consistent with the standards adopted by the California Public Utilities Commission (CPUC). This effort will help
protect energy customers from financial risks associated with investments in carbon-intensive generation by
allowing new capital investments in power plants whose GHG emissions are as low as or lower than new combined-
cycle natural gas plants by requiring imported electricity to meet GHG performance standards in California and by
requiring that the standards be developed and adopted in a public process.
SB X1 2. SB X1 2 (2011) expanded the RPS by establishing that 20% of the total electricity sold to retail customers
in California per year by December 31, 2013, and 33% by December 31, 2020, and in subsequent years be secured
from qualifying renewable energy sources. Under the bill, a renewable electrical generation facility is one that uses
biomass, solar thermal, photovoltaic, wind, geothermal, fuel cells using renewable fuels, small hydroelectric
generation of 30 megawatts or less, digester gas, municipal solid waste conversion, landfill gas, ocean wave, ocean
thermal, or tidal current, and that meets other specified requirements with respect to its location. In addition to the
retail sellers previously covered by the RPS, SB X1 2 added local, publicly owned electric utilities to the RPS.
SB 350. SB 350 (2015) further expanded the RPS by establishing that 50% of the total electricity sold to retail
customers in California per year by December 31, 2030 be secured from qualifying renewable energy sources. In
addition, SB 350 includes the goal to double the energy efficiency savings in electricity and natural gas final end
uses (such as heating, cooling, lighting, or class of energy uses on which an energy-efficiency program is focused)
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 25 JUNE 2022
of retail customers through energy conservation and efficiency. The bill also requires the CPUC, in consultation with
the CEC, to establish efficiency targets for electrical and gas corporations consistent with this goal.
SB 100 (2018) increased the standards set forth in SB 350 establishing that 44% of the total electricity sold to
retail customers in California per year by December 31, 2024, 52% by December 31, 2027, and 60% by December
31, 2030, be secured from qualifying renewable energy sources. Under SB 100, it is the policy of the state that
eligible renewable energy resources and zero-carbon resources supply 100% of the retail sales of electricity to
California. This bill requires that the achievement of 100% zero-carbon electricity resources does not increase the
carbon emissions elsewhere in the western grid and that the achievement not occur through resource shuffling.

AB 1493. In a response to the transportation sector accounting for more than half of California’s CO2 emissions,
AB 1493 was enacted in July 2002. AB 1493 required CARB to set GHG emission standards for passenger vehicles,
light-duty trucks, and other vehicles determined by the state board to be vehicles that are primarily used for
noncommercial personal transportation in the state. The bill required that CARB set GHG emission standards for
motor vehicles manufactured in 2009 and all subsequent model years. CARB adopted the standards in September
2004. When fully phased in, the near-term (2009–2012) standards will result in a reduction of about 22% in GHG
emissions compared to the emissions from the 2002 fleet, while the mid-term (2013–2016) standards will result
in a reduction of about 30%.
EO S-1-07. Issued on January 18, 2007, EO S-1-07 sets a declining Low Carbon Fuel Standard for GHG emissions
measured in CO2e grams per unit of fuel energy sold in California. The target of the Low Carbon Fuel Standard is to
reduce the carbon intensity of California passenger vehicle fuels by at least 10% by 2020. The carbon intensity
measures the amount of GHG emissions in the lifecycle of a fuel, including extraction/feedstock production,
processing, transportation, and final consumption, per unit of energy delivered. CARB adopted the implementing
regulation in April 2009. The regulation is expected to increase the production of biofuels, including those from
alternative sources, such as algae, wood, and agricultural waste.
SB 375. SB 375 (2008) addresses GHG emissions associated with the transportation sector through regional
transportation and sustainability plans. SB 375 required CARB to adopt regional GHG reduction targets for the
automobile and light-truck sector for 2020 and 2035. Regional metropolitan planning organizations (MPOs) are
then responsible for preparing a Sustainable Communities Strategy within their Regional Transportation Plan. The
goal of the Sustainable Communities Strategy is to establish a forecasted development pattern for the region that,
after considering transportation measures and policies, will achieve, if feasible, the GHG reduction targets. If a
Sustainable Communities Strategy is unable to achieve the GHG reduction target, an MPO must prepare an
Alternative Planning Strategy demonstrating how the GHG reduction target would be achieved through alternative
development patterns, infrastructure, or additional transportation measures or policies.
Pursuant to Government Code Section 65080(b)(2)(K), a sustainable communities strategy does not: (i) regulate
the use of land; (ii) supersede the land use authority of cities and counties; or (iii) require that a city’s or county’s
land use policies and regulations, including those in a general plan, be consistent with it. Nonetheless, SB 375
makes regional and local planning agencies responsible for developing those strategies as part of the federally
required metropolitan transportation planning process and the state-mandated housing element process.

In 2010, CARB adopted the first round of SB 375 targets for the regional MPOs. The original targets for San Diego
Association of Governments (SANDAG) are a 7% reduction in emissions per capita by 2020 and a 13% reduction
by 2035. In March 2018, CARB adopted updated SB 375 targets for the regional MPOs. The updated targets for
SANDAG are a 15% reduction in emissions per capita by 2020 and a 19% reduction by 2035. The reduction targets
are expressed as a percent change in per capita passenger vehicle GHG emissions relative to 2005 levels.
SANDAG completed and adopted its 2050 Regional Transportation Plan/Sustainable Communities Strategy
(RTP/SCS) in October 2011. In November 2011, CARB, by resolution, accepted SANDAG’s GHG emissions
quantification analysis and determination that, if implemented, the SCS would achieve CARB’s 2020 and 2035
GHG emissions reduction targets for the region.
In 2015, SANDAG adopted the next iteration of its RTP/SCS in accordance with statutorily mandated timelines.
More specifically, in October 2015, SANDAG adopted San Diego Forward: The Regional Plan. Like the 2050
RTP/SCS, this planning document meets CARB’s 2020 and 2035 reduction targets for the region (SANDAG 2015).
In December 2015, CARB, by resolution, accepted SANDAG’s GHG emissions quantification analysis and
determination that, if implemented, the SCS would achieve CARB’s 2020 and 2035 GHG emissions reduction
targets for the region.
On September 23, 2016, SANDAG’s Board of Directors adopted the final 2016 Regional Transportation
Improvement Program (RTIP), which is a multibillion-dollar, multiyear program of proposed major transportation
projects in the San Diego region. Transportation projects funded with federal, state, and TransNet (the San Diego
transportation sales tax program) must be included in an approved RTIP. The programming of locally funded
projects also may be programmed at the discretion of the agency. The 2016 RTIP covers five fiscal years and
incrementally implements the Regional Plan (SANDAG 2016). The latest draft of the 2021 Regional Plan was
released in May 2021 and at its meeting on February 26, 2021, the SANDAG Board of Directors adopted the final
2021 RTIP. The 2021 RTIP and its conformity determination were approved by FHWA and FTA on April 16, 2021.
The 2021 Regional Plan provides a long-term blueprint for the San Diego region that seeks to meet regulatory
requirements, address traffic congestion, and create equal access to jobs, education, healthcare, and other
community resources (SANDAG 2021). The plan is the result of years of planning, data analysis, and community
engagement to reimagine the San Diego region with a transformative transportation system, a sustainable pattern
of growth and development, and innovative demand and management strategies.
The 2021 Regional Plan includes a Sustainable Communities Strategy (SCS), as required by California Senate Bill
375 (SB 375), for the San Diego region. This SCS describes coordinated transportation and land use planning that
exceeds the state’s target for reducing per capita GHG emissions set by the California Air Resources Board. The
state-mandated target is a 19% reduction—compared with 2005—in per capita GHG emissions from cars and light-
duty trucks by 2035. The 2021 Regional Plan achieves a 20% reduction by then.
The 2021 Regional Plan also puts forth a forecasted development pattern that is driven by regional goals for
sustainability, mobility, housing affordability, and economic prosperity.
Advanced Clean Cars Program. In January 2012, CARB approved the Advanced Clean Cars program, a new
emissions-control program for model years 2015 through 2025. The program combines the control of smog- and
soot-causing pollutants and GHG emissions into a single coordinated package. The package includes elements to
reduce smog-forming pollution, reduce GHG emissions, promote clean cars, and provide the fuels for clean cars
(CARB 2011). To improve air quality, CARB has implemented new emission standards to reduce smog-forming
emissions beginning with 2015 model year vehicles. It is estimated that in 2025 cars will emit 75% less smog-
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 27 JUNE 2022
forming pollution than the average new car sold today. To reduce GHG emissions, CARB, in conjunction with the
EPA and the NHTSA, has adopted new GHG standards for model year 2017 to 2025 vehicles; the new standards
are estimated to reduce GHG emissions by 34% in 2025. The Zero Emissions Vehicle (ZEV) program will act as the
focused technology of the Advanced Clean Cars program by requiring manufacturers to produce increasing numbers
of ZEVs and plug-in hybrid electric vehicles in the 2018 to 2025 model years. The Clean Fuels Outlet regulation will
ensure that fuels such as electricity and hydrogen are available to meet the fueling needs of the new advanced
technology vehicles as they come to the market.
EO B-16-12. EO B-16-12 (2012) directs state entities under the Governor’s direction and control to support and
facilitate development and distribution ZEVs. This EO also sets a long-term target of reaching 1.5 million zero-
emission vehicles on California’s roadways by 2025. On a statewide basis, EO B-16-12 also establishes a GHG
emissions reduction target from the transportation sector equaling 80% less than 1990 levels by 2050. In
furtherance of this EO, the Governor convened an Interagency Working Group on Zero-Emission Vehicles that has
published multiple reports regarding the progress made on the penetration of ZEVs in the statewide vehicle fleet.
SB 350. In 2015, SB 350 – the Clean Energy and Pollution Reduction Act – was enacted into law. As one of its
elements, SB 350 establishes a statewide policy for widespread electrification of the transportation sector,
recognizing that such electrification is required for achievement of the state’s 2030 and 2050 reduction targets
(see Public Utilities Code section 740.12).
EO B-48-18 (2018) launched an eight-year initiative to accelerate the sale of EVs through a mix of rebate programs
and infrastructure improvements. The order also set a new EV target of 5 million EVs in California by 2030. EO B-
48-18 included funding for multiple state agencies, including the CEC, to increase EV charging infrastructure and
for CARB to provide rebates for the purchase of new EVs and purchase incentives for low-income customers.
Solid Waste
AB 939 and AB 341. In 1989, AB 939, known as the Integrated Waste Management Act (Public Resources Code
Sections 40000 et seq.), was passed because of the increase in waste stream and the decrease in landfill capacity.
The statute established the California Integrated Waste Management Board, which oversees a disposal reporting
system. AB 939 mandated a reduction of waste being disposed where jurisdictions were required to meet diversion
goals of all solid waste through source reduction, recycling, and composting activities of 25% by 1995 and 50% by
the year 2000.
AB 341 (2011) amended the California Integrated Waste Management Act of 1989 to include a provision declaring
that it is the policy goal of the state that not less than 75% of solid waste generated be source-reduced, recycled,
or composted by the year 2020, and annually thereafter. In addition, AB 341 required the California Department of
Resources Recycling and Recovery (CalRecycle) to develop strategies to achieve the state’s policy goal. CalRecycle
has conducted multiple workshops and published documents that identify priority strategies that CalRecycle
believes would assist the state in reaching the 75% goal by 2020.
Increasing the amount of commercial solid waste that is recycled, reused, or composted will reduce GHG emissions
primarily by 1) reducing the energy requirements associated with the extraction, harvest, and processing of raw
materials and 2) using recyclable materials that require less energy than raw materials to manufacture finished
products (CalRecycle 2015). Increased diversion of organic materials (green and food waste) will also reduce GHG
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 28 JUNE 2022
emissions (CO2 and CH4) resulting from decomposition in landfills by redirecting this material to processes that use
the solid waste material to produce vehicle fuels, heat, electricity, or compost.
Water
EO B-29-15. In response to the ongoing drought in California, EO B-29-15 (April 2015) set a goal of achieving a
statewide reduction in potable urban water usage of 25% relative to water use in 2013. The term of the EO extended
through February 28, 2016, although many of the directives have since become permanent water-efficiency
standards and requirements. The EO includes specific directives that set strict limits on water usage in the state.
In response to EO B-29-15, the California Department of Water Resources has modified and adopted a revised
version of the Model Water Efficient Landscape Ordinance that, among other changes, significantly increases the
requirements for landscape water use efficiency and broadens its applicability to include new development projects
with smaller landscape areas.
Other State Regulations and Goals
SB 97 (August 2007) directed the Governor’s Office of Planning and Research (OPR) to develop guidelines under
CEQA for the mitigation of GHG emissions. In 2008, OPR issued a technical advisory as interim guidance regarding
the analysis of GHG emissions in CEQA documents. The advisory indicated that the lead agency should identify and
estimate a project’s GHG emissions, including those associated with vehicular traffic, energy consumption, water
usage, and construction activities (OPR 2008). The advisory further recommended that the lead agency determine
significance of the impacts and impose all mitigation measures necessary to reduce GHG emissions to a level that
is less than significant. The California Natural Resources Agency (CNRA) adopted the CEQA Guidelines amendments
in December 2009, which became effective in March 2010.
Under the amended CEQA Guidelines, a lead agency has the discretion to determine whether to use a quantitative
or qualitative analysis or apply performance standards to determine the significance of GHG emissions resulting
from a particular project (14 CCR 15064.4[a]). The CEQA Guidelines require a lead agency to consider the extent
to which a project complies with regulations or requirements adopted to implement a statewide, regional, or local
plan for the reduction or mitigation of GHG emissions (14 CCR 15064.4[b]). The CEQA Guidelines also allow a lead
agency to consider feasible means of mitigating the significant effects of GHG emissions, including reductions in
emissions through the implementation of project features or off-site measures. The adopted amendments do not
establish a GHG emission threshold, instead allowing a lead agency to develop, adopt, and apply its own thresholds
of significance or those developed by other agencies or experts. The CNRA also acknowledges that a lead agency
may consider compliance with regulations or requirements implementing AB 32 in determining the significance of
a project’s GHG emissions (CNRA 2009a).
With respect to GHG emissions, the CEQA Guidelines, Section 15064.4(a), state that lead agencies should “make
a good faith effort, to the extent possible on scientific and factual data, to describe, calculate or estimate” GHG
emissions. The CEQA Guidelines note that an agency may identify emissions by either selecting a “model or
methodology” to quantify the emissions or by relying on “qualitative analysis or performance based standards” (14
CCR 15064.4[a, c]). Section 15064.4(b) states that the lead agency should consider the following when assessing
the significance of impacts from GHG emissions on the environment: (1) the extent a project may increase or reduce
GHG emissions as compared to the existing environmental setting; (2) whether project emissions exceed a
threshold of significance that the lead agency determines applies to the project; and (3) the extent to which a project
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 29 JUNE 2022
complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the
reduction or mitigation of GHG emissions (14 CCR 15064.4[b]).
EO S-13-08. EO S-13-08 (November 2008) is intended to hasten California’s response to the impacts of global
climate change, particularly sea-level rise. Therefore, the EO directs state agencies to take specified actions to
assess and plan for such impacts. The final 2009 California Climate Adaptation Strategy report was issued in
December 2009 (CNRA 2009a), and an update, Safeguarding California: Reducing Climate Risk, followed in July
2014 (CNRA 2014). To assess the state’s vulnerability, the report summarizes key climate change impacts to the
state for the following areas: agriculture, biodiversity and habitat, emergency management, energy, forestry, ocean
and coastal ecosystems and resources, public health, transportation, and water. Issuance of the Safeguarding
California: Implementation Action Plans followed in March 2016 (CNRA 2016). In January 2018, the CNRA released
the Safeguarding California Plan: 2018 Update, which communicates current and needed actions that state
government should take to build climate change resiliency (CNRA 2018).
3.3 Local
City of Carlsbad General Plan
The State of California requires cities and counties to prepare and adopt a general plan to set out a long-range
vision and comprehensive policy framework for its future. The State also mandates that the general plan be updated
periodically to ensure relevance and utility. The City of Carlsbad General Plan (General Plan) was unanimously
adopted by the City Council on September 22, 2015. The General Plan builds upon many of the goals and strategies
of the former 1994 General Plan, in addition to offering new policy direction in the areas of urban form,
neighborhood character, historic preservation, public facilities, recreation, conservation, mobility, housing
affordability, economic prosperity, and equitable development. It also outlines the plan amendment process, and
other implementation strategies, and considers the continued growth of the City beyond the year 2020 (City of
Carlsbad 2015a).
Sustainability Element. The Sustainability Element provides the overarching framework and includes policies
focused on topics central to sustainability not covered elsewhere. This element provides the overarching framework
for sustainability in the City and outlines policies focused on:
▪ Climate change and GHG reduction;
▪ Water conservation, recycling, and supply;
▪ Green building;
▪ Sustainable energy and energy security; and
▪ Sustainable food.
The Sustainability Element is closely tied to the City’s Community Vision Core Value 6-Sustainability, which aims to
build on the City’s sustainability initiatives to emerge as a leader in green development and sustainability, and
pursue public/ private partnerships, particularly on sustainable water, energy, recycling, and foods. The following
goals identified in the Sustainability Element support reduction of GHG emissions in the City:
▪ 9-G.2: Undertake initiatives to enhance sustainability by reducing the community’s GHG emissions and
fostering green development patterns—including buildings, sites, and landscapes.
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 30 JUNE 2022
▪ 9-G.3: Promote energy efficiency and conservation in the community.
The following policies identified in the Sustainability Element support reduction of GHG emissions in the City:
▪ 9-P.1: Enforce the Climate Action Plan as the city’s strategy to reduce greenhouse gas emissions.
▪ 9-P.2: Continue efforts to decrease use of energy and fossil fuel consumption in municipal operations,
including transportation, waste reduction and recycling, and efficient building design and use.
The Sustainability Element also identifies policies for water conservation, recycling, and supply; green building;
sustainable energy; and sustainable food.
City of Carlsbad Climate Action Plan
The City of Carlsbad Climate Action Plan (CAP) was unanimously adopted by the City Council on September 22,
2015 (City of Carlsbad 2015b). The City Council approved CAP Amendment No. 1, which included the establishment
of a 2020 GHG inventory, recalculation of GHG emission targets and forecasts, and incorporation Community
Choice Energy as a CAP measure. These revisions were made to the CAP to allow the city to meet its 2020 and
2035 GHG reduction targets, enable the plan to be considered a qualified CAP under CEQA, and be used to
streamline the permit process through discretionary environmental review.
The CAP is designed to reduce the City’s GHG emissions and streamline environmental review of future
development projects in the city in accordance with the California Environmental Quality Act (CEQA).
The CAP includes goals, policies, and actions for the City to reduce GHG emissions and combat climate change and
includes: an inventory of 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 the City’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 CAP extends from the date of adoption through 2035. The CAP is considered a qualified
plan as described in CEQA Guidelines Section 15183.5(b).
The CAP is intended to be a tool for policy makers, community members and others to guide the implementation of
actions that limit the City’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.
The CAP set the GHG reduction goals for the City at 15% below 2005 levels by 2020, 49% reduction by 2035, and
80% reduction by 2050. The GHG reduction measures outlined in the CAP include the following categories (City of
Carlsbad 2020):
▪ 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)
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 31 JUNE 2022
▪ Citywide renewable projects
▪ Water delivery and conservation
The CAP also outlines two approaches for projects to show consistency with the CAP (City of Carlsbad 2015b):
▪ Checklist Approach. The Project Review Checklist 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 of the CAP 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.
CAP CEQA Streamlining - Project Screening Thresholds
The California Air Pollution Control Officers Association (CAPCOA) provides 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.

provided in Appendix G of the CEQA Guidelines. For the purposes of this GHG emissions analysis, the Project would
have a significant environmental impact if it would (14 CCR 15000 et seq.):
1. Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment?
2. Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions
of GHGs?
The Appendix G thresholds for GHGs do not prescribe specific methodologies for performing an assessment, do not
establish specific quantitative thresholds, and do not mandate specific mitigation measures. Rather, the CEQA
Guidelines emphasize the lead agency’s discretion to determine the appropriate methodologies and thresholds of
significance consistent with the manner in which other impact areas are handled in CEQA (CNRA 2009a). Additional
guidance regarding assessment of GHG’s is discussed below.
CEQA Guidelines
With respect to GHG emissions, the CEQA Guidelines Section 15064.4(a) states that lead agencies “shall make a
good-faith effort, based to the extent possible on scientific and factual data, to describe, calculate or estimate”
GHG emissions resulting from a project. The CEQA Guidelines note that an agency has the discretion to either
quantify a project’s GHG emissions or rely on a “qualitative analysis or performance based standards” (14 CCR
15064.4[a]). A lead agency may use a “model or methodology” to estimate greenhouse gas emissions and has the
discretion to select the model or methodology it considers “most appropriate to enable decision makers to
intelligently take into account the project’s incremental contribution to climate change” (14 CCR 15064.4[c]). The
CEQA Guidelines provide that the lead agency should consider the following when determining the significance of
impacts from GHG emissions on the environment (14 CCR 15064.4[b]):
1. The extent a project may increase or reduce GHG emissions as compared to the existing environmental setting.
2. Whether the project emissions exceed a threshold of significance that the lead agency determines applies
to the project.
3. The extent to which the project complies with regulations or requirements adopted to implement a
statewide, regional, or local plan for the reduction or mitigation of GHG emissions.
In addition, the CEQA Guidelines specify that “[w]hen adopting or using thresholds of significance, a lead agency
may consider thresholds of significance previously adopted or recommended by other public agencies, or
recommended by experts, provided the decision of the lead agency to adopt such thresholds is supported by
substantial evidence” (14 CCR 15064.7[c]).
Governor’s Office of Planning and Research Guidance
The Governor’s Office of Planning and Research (OPR) technical advisory titled, CEQA and Climate Change:
Addressing Climate Change through California Environmental Quality Act (CEQA) Review, states that “public
agencies are encouraged but not required to adopt thresholds of significance for environmental impacts. Even in
the absence of clearly defined thresholds for GHG emissions, the law requires that such emissions from CEQA
PONTO STORAGE TOWNHOMES PROJECT / GREENHOUSE GAS EMISSIONS ANALYSIS
14183 34 JUNE 2022
projects must be disclosed and mitigated to the extent feasible whenever the lead agency determines that the
project contributes to a significant, cumulative climate change impact” (OPR 2008). Furthermore, the advisory
document indicates that “in the absence of regulatory standards for GHG emissions or other scientific data to clearly
define what constitutes a ‘significant impact,’ individual lead agencies may undertake a project-by-project analysis,
consistent with available guidance and current CEQA practice” (OPR 2008).
Cumulative Nature of Climate Change
Global climate change is a cumulative impact; a project participates in this potential impact through its incremental
contribution combined with the cumulative increase of all other sources of GHGs. There are currently no established
thresholds for assessing whether the GHG emissions of a project in the San Diego Air Basin (SDAB), such as the
Project, would be considered a cumulatively considerable contribution to global climate change; however, all
reasonable efforts should be made to minimize a project’s contribution to global climate change.
While the Project would result in emissions of GHGs during construction and operation, no current guidance exists
to indicate what level of GHG emissions would be considered substantial enough to result in a significant adverse
impact on global climate. However, it is generally believed that an individual project is of insufficient magnitude by
itself to directly influence climate change as scientific uncertainty regarding the significance a project’s individual
and cumulative effects on global climate change remains.
Thus, GHG impacts are recognized as exclusively cumulative impacts; there are no non-cumulative GHG emission
impacts from a climate change perspective (CAPCOA 2008). This approach is consistent with that recommended
by the CNRA, which noted in its Public Notice for the proposed CEQA amendments (pursuant to SB97) that the
evidence before it indicates that in most cases, the impact of GHG emissions should be considered in the context
of a cumulative impact, rather than a project-level impact (CNRA 2009a). Similarly, the Final Statement of Reasons
for Regulatory Action on the CEQA Amendments confirm that an environmental impact report or other environmental
document must analyze the incremental contribution of a project to GHG levels and determine whether those
emissions are cumulatively considerable (CNRA 2009a).
Approaches to Determining Significance
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. Projects greater than 900 MTCO2e would be required to show CAP Checklist consistency.

5 Impacts
Would the Project generate greenhouse gas emissions, either directly or indirectly, that may have a significant
impact on the environment?
Would the Project conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the
emissions of greenhouse gases?
Project GHG Emissions
Construction GHG Emissions
Construction Scenario Assumptions
GHG emissions would be associated with the construction phase of the Project components through use of
construction equipment and vehicle trips. Emissions of CO2 were estimated using the California Emissions
Estimator Model (CalEEMod), Version 2020.4.0.3
For the purposes of modeling, it was assumed that construction of Project components would commence in March
2023 and last approximately 22 months. Table 5 provides the construction timeline and potential phasing of the
components that would come online to achieve the target milestones. The construction schedule has been
developed based on available information provided by the Project applicant, typical construction practices, and best
engineering judgment. Construction phasing is intended to represent a schedule of anticipated activities for use in
estimating potential Project-generated construction emissions.

3 CalEEMod is a statewide land use emissions computer model designed to provide a uniform platform to calculate construction
and operational emissions from land use development projects. The model was developed for the California Air Pollution Control
Officers Association in collaboration with multiple air districts across the State. Numerous lead agencies in the State, including
the SDAPCD, utilize CalEEMod to estimate GHG emissions in accordance with CEQA Guidelines section 15064.4(a)(1).

The equipment mix assumptions were based on Project design documents, review of related documents, and
CalEEMod default equipment, where appropriate. The equipment mix is meant to represent a reasonably
conservative estimate of construction activity. For the analysis, it is generally assumed that heavy construction
equipment would be operating at the site for approximately 8 hours per day, 5 days per week. Default assumptions
provided in CalEEMod were utilized to determine worker trips and vendor truck trips for each potential construction
phase. The default CalEEMod trip distance for construction vehicles was assumed, which was a one-way distance
of 10.8 miles for worker trips, 7.3 miles for vendor trips, and a project specific value of 25 miles for haul trips.
Based on project specific information, 50 cubic yards of material export is expected from the construction of the
project and included in the modeling analysis.
Estimated Construction Emissions
Table 6 shows the estimated annual GHG construction emissions associated with the Project. Complete details of
the emissions calculations are provided in Appendix A of this document.

See Appendix A for complete results. <0.01 = reported value is less than 0.01.
As shown in Table 6, the estimated total GHG emissions from construction of the Project would be 511 MT CO2e.
When amortized over 30 years, the estimated annual GHG emissions from construction of the Project would be 17
MT CO2e per year.
Operational Emissions
Operation of the Project would result in direct GHG emissions from area sources, indirect GHG emissions from use
of electricity, vehicular traffic, waste, and water and wastewater including a wastewater lift station pump.
Operational Scenario Assumptions
Area
The area source category calculates direct sources of GHG emissions located at the Project site including hearths
and landscape maintenance equipment. (This source category does not include the emissions associated with
natural gas usage in space heating and water heating as these are calculated in the building energy use module of
CalEEMod.) The Project will not have natural gas or woodburning fireplaces or woodstoves; as such, the only area
source pertinent to this analysis is landscape maintenance equipment.
Landscape maintenance includes fuel combustion emissions from equipment such as lawn mowers, roto tillers,
shredders/grinders, blowers, trimmers, chain saws, and hedge trimmers, as well as air compressors, generators,
and pumps. The emissions associated from landscape equipment use were estimated using CalEEMod defaults.
For San Diego County, CalEEMod assumes that landscaping equipment would operate 180 days per year. To be
conservative, emissions were estimated assuming that landscape maintenance equipment was powered by
gasoline or diesel fuel, and not electrified.
Energy
As represented in CalEEMod, energy sources include emissions associated with building electricity and natural gas
usage (non-hearth). CalEEMod default values for energy consumption were applied to each land use. The energy
use from residential land uses is calculated in CalEEMod based on the Residential Appliance Saturation Survey
(CAPCOA 2021).
Annual natural gas (non-hearth) and electricity emissions were estimated in CalEEMod using default values for
emissions factors for San Diego Gas and Electric (SDG&E), which would be the energy source provider for the Project.
Mobile Sources (Motor Vehicles)
Following the completion of construction activities, the Project would generate GHG emissions from mobile sources
(vehicular traffic), as a result of residents and employees associated with the 86 residential units. The CalEEMod
Version 2020.4.0 model was used to estimate daily emissions from vehicular sources (refer to Appendix A).
CalEEMod Version 2020.4.0 default data, including temperature, trip characteristics, variable start information,
and emissions factors were used for the model inputs. Project specific trip rates, and transportation demand

management (TDM) measures including increased residential density and percent affordable housing, were taken
from the Linscott Law & Greenspan VMT Analyses, May 18, 2022, LLG Ref. 3-22-3538. Emission factors
representing the vehicle mix and emissions for 2025 were conservatively used to estimate emissions associated
with vehicular sources. The 2025 operational year represents the first full year the Project would be operational.
Solid Waste
The Project would generate solid waste, and therefore, result in CO2e emissions associated with landfill off-gassing.
CalEEMod default values for solid waste generation were used to estimate GHG emissions associated with solid waste.
Water and Wastewater
Supply, conveyance, treatment, and distribution of water for the Project require the use of electricity, which would
result in associated indirect GHG emissions. Similarly, wastewater generated by the Project requires the use of
electricity for conveyance and treatment, along with GHG emissions generated during wastewater treatment. Water
consumption estimates for both indoor and outdoor water use and associated electricity consumption from water
use and wastewater generation were estimated using CalEEMod default values.
Stationary Source
The project would require a wastewater lift station for intermittent transfer of wastewater from the operation of the
project. The lift station requires a wastewater pump and 15 horsepower (hp) engine. The lift station would normally
be operated by and electric motor and would have a diesel engine as back up in the event electrical power is
interrupted to the electric motor. The expected operation of the lift station is 1 hour per day in two 30-minute
intervals over the course of the day. For worst case GHG emission operating scenario, the total operation was
modeled with diesel backup engine operating.
Estimated Operational Emissions
Table 7 shows the total operational GHG emissions for the Project after accounting for amortized construction emissions.

Impact Analysis
Consistency with the City of Carlsbad CAP
Implementation of the Project would emit approximately 765 MT CO2e per year. The Project-generated operational
emissions in 2025 plus amortized project construction emissions would be less than the City’s CAP GHG threshold
of 900 MT CO2e per year. As such, the Project would be consistent with the CAP and would not be required to
complete the CAP Checklist. Impacts would be less than significant.
