The report has been prepared by Rincon Consultants, Inc. for use by the City of Carlsbad in support of the environmental documentation being prepared pursuant to the California Environmental Quality Act (CEQA) . The purpose of this study is to analyze the proposed project's GHG emissions and the associated impact to global climate change. 1bis study describes global climate change, GHGs, the current regulatory framework, quantifies GHG emissions for the proposed project, compares forecast emissions to quantitative thresholds, and discusses the project's consistency with both state and local legislation including the City of Carlsbad Climate Action Plan (CAP) . PROJECT DESCRIPTION The proposed project involves the construction of a 250-room hotel, which would be built in place of an existing 137,999 square foot parking lot located between the resort's main gate and the existing hotel. The proposed project is located at 1 Legoland Drive, Carlsbad, California. The proposed hotel (shown below in white) would be three stories and include 250 rooms with an associated restaurant, gift shop, and outdoor play areas for children. The existing onsite parking located on the south of the project site would remain and be used as parking for the new hotel. r City of Carlsbad e e e C ,C e C C C C e C e • e C • C C C e C) e e C e e C e C ~ • e C • C C • C C e C Legoland Hotel Project Greenhouse Gas Study SETTING Overview of Global Climate Change Climate Change and Greenhouse Gases Climate change is the observed increase in the average temperature of the Earth's atmosphere and oceans along with other substantial changes in climate (such as wind patterns, precipitation, and storms) over an extended period of time. The term "climate change" is often used interchangeably with the term "global warming," but "climate change" is preferred to "global warming" because it helps convey that there are other changes in addition to rising temperatures. The baseline against which these changes are measured originates in historical records identifying temperature changes that have occurred in the past, such as during previous ice ages. The global climate is continuously changing, as evidenced by repeated episodes of substantial warming and cooling documented in the geologic record. The rate of change has typically been incremental, with warming or cooling trends occurring over the course of thousands of years. The past 10,000 years have been marked by a period of incremental warming, as glaciers have steadily retreated across the globe. However, scientists have observed acceleration in the rate of warming during the past 150 years. Per the United Nations Intergovernmental Panel on Climate Change (IPCC, 2013), the understanding of anthropogenic warming and cooling influences on climate has led to a high confidence (95 percent or greater chance) that the global average net effect of human activities has been the dominant cause of warming since the mid-20th century (IPCC, 2013). Gases that absorb and re-emit infrared radiation in the atmosphere are called greenhouse gases (GHGs). The gases that are widely seen as the principal contributors to human-induced climate change include carbon dioxide (COi), methane (CI-L), nitrous oxides (NiO), fluorinated gases such as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Water vapor is excluded from the list of GHGs because it is short-lived in the atmosphere and its atmospheric concentrations are largely determined by natural processes, such as oceanic evaporation. GHGs are emitted by both natural processes and human activities. Of these gases, COi and CI-L are emitted in the greatest quantities from human activities. Emissions of CO2 are largely by- products of fossil fuel combustion, whereas CI-L results from off-gassing associated with agricultural practices and landfills. Observations of CO2 concentrations, globally-averaged temperature, and sea level rise are generally well within the range of the extent of the earlier IPCC projections. The recently observed increases in CI-L and NiO concentrations are smaller than those assumed in the scenarios in the previous assessments. Each IPCC assessment has used new projections of future climate change that have become more detailed as the models have become more advanced . Man-made GHGs, many of which have greater heat-absorption potential than COi, include fluorinated gases and sulfur hexafluoride (SF6) (California Environmental Protection Agency [CalEP A], 2006). Different types of GHGs have varying global warming potentials (GWPs). The GWP of a GHG is the potential of a gas or aerosol to trap heat in the atmosphere over a specified timescale (generally, 100 years). Because GHGs absorb different amounts of heat, a common reference gas (COi) is used to relate the amount of heat absorbed to the amount of the gas emissions, referred to as "carbon dioxide equivalent" (CO2e), and is the amount of a GHG emitted multiplied by its GWP. Carbon dioxide has a 100-year GWP of one. By contrast, methane CI-L has r City of Carlsbad 2 e " e C C C C e C e e e C • C C C e e C) e e e C e C C C e • e e • C C • C tD e e Legoland Hotel Project Greenhouse Gas Study a GWP of 25, meaning its global warming effect is 25 times greater than carbon dioxide on a molecule per molecule basis (IPCC, 2007). The accumulation of GHGs in the atmosphere regulates the earth's temperature. Without the natural heat trapping effect of GHGs, Earth's surface would be about 34 ° C cooler (CalEP A, 2006). However, it is believed that emissions from human activities, particularly the consumption of fossil fuels for electricity production and transportation, have elevated the concentration of these gases in the atmosphere beyond the level of naturally occurring concentrations. The following discusses the primary GHGs of concern. Carbon Dioxide The global carbon cycle is made up of large carbon flows and reservoirs. Billions of tons of carbon in the form of CO2 are absorbed by oceans and living biomass (i.e., sinks) and are emitted to the atmosphere annually through natural processes (i.e., sources). When in equilibrium, carbon fluxes among these various reservoirs are roughly balanced (United States Environmental Protection Agency [U.S. EPA], 2014). CO2 was the first GHG demonstrated to be increasing in atmospheric concentration, with the first conclusive measurements being made in the second half of the 20th century. Concentrations of CO:iin the atmosphere have risen approximately 40 percent since the industrial revolution. The global atmospheric concentration of CO2 has increased from a pre- industrial value of about 280 parts per million (ppm) to 391 ppm in 2011 (IPCC, 2007; Oceanic and Atmospheric Administration [NOAA], 2010). The average annual CO2 concentration growth rate was larger between 1995 and 2005 (average: 1.9 ppm per year) than it has been since the beginning of continuous direct atmospheric measurements (1960-2005 average: 1.4 ppm per year), although there is year-to-year variability in growth rates (NOAA, 2010). Currently, CO:i represents an estimated 74 percent of total GHG emissions (IPCC, 2007). The largest source of CO2 emissions, and of overall GHG emissions, is fossil fuel combustion. Methane Methane (~) is an effective absorber of radiation, though its atmospheric concentration is less than that of CO2 and its lifetime in the atmosphere is limited to 10 to 12 years. It has a GWP approximately 25 times that of CO:i. Over the last 250 years, the concentration of ~ in the atmosphere has increased by 148 percent (IPCC, 2007), although emissions have declined from 1990 levels. Anthropogenic sources of~ include enteric fermentation associated with domestic livestock, landfills, natural gas and petroleum systems, agricultural activities, coal mining, wastewater treatment, stationary and mobile combustion, and certain industrial processes (U.S. EPA, 2014). Nitrous Oxide Concentrations of nitrous oxide (NiO) began to rise at the beginning of the industrial revolution and continue to increase at a relatively uniform growth rate (NOAA, 2010). NiO is produced by microbial processes in soil and water, including those reactions that occur in fertilizers that contain nitrogen, fossil fuel combustion, and other chemical processes. Use of these fertilizers has increased over the last century. Agricultural soil management and mobile source fossil fuel combustion are the major sources of N2O emissions. The GWP of nitrous oxide is approximately 298 times that of CO:i (IPCC, 2007). Fluorinated Gases (HFCS, PFCS and SF6) Fluorinated gases, such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and r City of Carlsbad 3 • C e e C ~ C C C • e tD e I) e C C e C C • • C e • C) e e e C e • " e e • C • e • e e Legoland Hotel Project Greenhouse Gas Study sulfurhexafluoride (SF6), are powerful GHGs that are emitted from a variety of industrial processes. Fluorinated gases are used as substitutes for ozone-depleting substances such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons, which have been regulated since the mid-1980s because of their ozone-destroying potential and are phased out under the Montreal Protocol (1987) and Oean Air Act Amendments of 1990. Electrical transmission and distribution systems account for most SF6 emissions, while PFC emissions result from semiconductor manufacturing and as a by-product of primary aluminum production. Fluorinated gases are typically emitted in smaller quantities than COi., G-1°4, and N20, but these compounds have much higher GWPs. SF6 is the most potent GHG the IPCC has evaluated . Greenhouse Gas Inventory Worldwide anthropogenic emissions of GHGs were approximately 46,000 million metric tons (MMT, or gigatonne) COie in 2010 (IPCC, 2014). COi emissions from fossil fuel combustion and industrial processes contributed about 65 percent of total emissions in 2010. Of anthropogenic GHGs, carbon dioxide was the most abundant accounting for 76 percent of total 2010 emissions. Methane emissions accounted for 16 percent of the 2010 total, while nitrous oxide and fluorinated gases account for 6 and 2 percent respectively (IPCC, 2014). Total U.S. GHG emissions were 6,870 MMT COie in 2014 (U.S. EPA, 2016). Total U.S. emissions have increased by 7.4 percent since 1990; emissions increased by 1 percent from 2013 to 2014 (U.S. EPA, 2016). The increase from 2013 to 2014 was due to numerous factors including an increase in total miles traveled by on-road vehicles and year-to-year changes in the prevailing weather. Since 1990, U.S. emissions have increased at an average annual rate of 0.2 percent. In 2014, the transportation and industrial end-use sectors accounted for 26 percent and 21 percent of COi emissions (with electricity-related emissions distributed), respectively. Meanwhile, the residential and commercial end-use sectors accounted for 12 percent of CO2 emissions (U.S. EPA, 2016). Based upon the California Air Resources Board (ARB) California Greenhouse Gas Inventory for 2000-2013, California produced 459.3 MMT COiE in 2013 (ARB, 2015). The major source of GHG in California is transportation, contributing 37 percent of the state's total GHG emissions. Industrial sources are the second largest source of the state's GHG emissions (CARB, 2015). California emissions are due in part to its large size and large population compared to other states. However, a factor that reduces California's per capita fuel use and GHG emissions, as compared to other states, is its relatively mild climate. The ARB has projected statewide unregulated GHG emissions for the year 2020 will be 509.4 MMT COie (ARB, 2014). These projections represent the emissions that would be expected to occur in the absence of any GHG reduction actions. Potential Effects of Global Climate Change Globally, climate change has the potential to affect numerous environmental resources through potential impacts related to future air temperatures and precipitation patterns. Scientific modeling predicts that continued GHG emissions at or above current rates would induce more extreme climate changes during the 21st century than were observed during the 20th century . Long-term trends have found that each of the past three decades has been warmer than all the previous decades in the instrumental record, and the decade from 2000 through 2010 has been the warmest. The global combined land and ocean temperature data show an increase of about 0.89°C (0.69°C-1.08°q over the period 1901-2012 and about 0.72°C (0.49°C-0.89°q over the r City of Carlsbad 4 C • e e ., e C C C e • C e e • C • e • e e e ,c C e • C) e e e C e • e C) e • C • C • • e Legoland Hotel Project Greenhouse Gas Study period 1951-2012 when described by a linear trend. Several independently analyzed data records of global and regional Land-Surface Air Temperature (LSAT) obtained from station observations are in agreement that LSAT as well as sea surface temperatures have increased. In addition to these findings, there are identifiable signs that global warming is currently taking place, including substantial ice loss in the Arctic over the past two decades (IPCC, 2013). According to the CalEPA's 2010 Climate Action Team Biennial Report, potential impacts of climate change in California may include loss in snow pack, sea level rise, more extreme heat days per year, more high ozone days, more large forest fires, and more drought years (CalEPA, 2010) . Below is a summary of some of the potential effects that could be experienced in California as a result of climate change. Air Quality Higher temperatures, which are conducive to air pollution formation, could worsen air quality in California. Oimate change may increase the concentration of ground-level ozone, but the magnitude of the effect, and therefore its indirect effects, are uncertain. If higher temperatures are accompanied by drier conditions, the potential for large wildfires could increase, which, in turn, would further worsen air quality. However, if higher temperatures are accompanied by wetter, rather than drier conditions, the rains would tend to temporarily dear the air of particulate pollution and reduce the incidence of large wildfires, thereby ameliorating the pollution associated with wildfires. Additionally, severe heat accompanied by drier conditions and poor air quality could increase the number of heat-related deaths, illnesses, and asthma attacks throughout the state (California Energy Commission [CEC], 2009). Water Supply Analysis of paleoclimatic data (such as tree-ring reconstructions of stream flow and precipitation) indicates a history of naturally and widely varying hydrologic conditions in California and the west, including a pattern of recurring and extended droughts. Uncertainty remains with respect to the overall impact of climate change on future water supplies in California. However, the average early spring snowpack in the Sierra Nevada decreased by about 10 percent during the last century, a loss of 1.5 million acre-feet of snowpack storage. During the same period, sea level rose eight inches along California's coast. California's temperature has risen 1 °F, mostly at night and during the winter, with higher elevations experiencing the highest increase. Many Southern California cities have experienced their lowest recorded annual precipitation twice within the past decade. In a span of only two years, Los Angeles experienced both its driest and wettest years on record (California Department of Water Resources [DWR], 2008; CCCC, 2009). This uncertainty complicates the analysis of future water demand, especially where the relationship between climate change and its potential effect on water demand is not well understood. The Sierra snowpack provides the majority of California's water supply by accumulating snow during the state's wet winters and releasing it slowly during the state's dry springs and summers. Based upon historical data and modeling DWR projects that the Sierra snowpack will experience a 25 to 40 percent reduction from its historic average by 2050. Oimate change is also anticipated to bring warmer storms that result in less snowfall at lower elevations, reducing the total snowpack (DWR, 2008) . r City of Carlsbad 5 C • C C • C r C C e e e C, e • C • e e C C e I) C e e C • e e C I) • C C) e ,. C • C e • e Legoland Hotel Project Greenhouse Gas Study Hydrology and Sea Level Rise As discussed above, climate change could potentially affect: the amount of snowfall, rainfall, and snow pack; the intensity and frequency of storms; flood hydrographs (flash floods, rain or snow events, coincidental high tide and high runoff events); sea level rise and coastal flooding; coastal erosion; and the potential for salt water intrusion. According to The Impacts of Sea- Level Rise on the California Coast, prepared by the California Climate Change Center (CCCq (CCCC, 2009), climate change has the potential to induce substantial sea level rise in the coming century. The rising sea level increases the likelihood and risk of flooding. The rate of increase of global mean sea levels over the 2001-2010 decade, as observed by satellites, ocean buoys and land gauges, was approximately 3.2 mm per year, which is double the observed 20th century trend of 1.6 mm per year (World Meteorological Organization [WMO], 2013). As a result, sea levels averaged over the last decade were about 8 inches higher than those of 1880 (WMO, 2013). Sea levels are rising faster now than in the previous two millennia, and the rise is expected to accelerate, even with robust GHG emission control measures. The most recent IPCC report (2013) predicts a mean sea-level rise of 11-38 inches by 2100. This prediction is more than 50 percent higher than earlier projections of 7-23 inches, when comparing the same emissions scenarios and time periods. A rise in sea levels could result in coastal flooding and erosion and could jeopardize California's water supply due to salt water intrusion. In addition, increased CO2 emissions can cause oceans to acidify due to the carbonic acid it forms. Increased storm intensity and frequency could affect the ability of flood-control facilities, including levees, to handle storm events. Agriculture California has a $30 billion annual agricultural industry that produces half of the country's fruits and vegetables. Higher CO2 levels can stimulate plant production and increase plant water-use efficiency. However, if temperatures rise and drier conditions prevail, water demand could increase; crop-yield could be threatened by a less reliable water supply; and greater air pollution could render plants more susceptible to pest and disease outbreaks. In addition, temperature increases could change the time of year certain crops, such as wine grapes, bloom or ripen, and thereby affect their quality (CCCC, 2006). Ecosystems and Wildlife Climate change and the potential resulting changes in weather patterns could have ecological effects on a global and local scale. Increasing concentrations of GHGs are likely to accelerate the rate of climate change. Scientists project that the average global surface temperature could rise by l.0-4.5°F (0.6-2.5°C) in the next 50 years, and 2.2-10°F (l.4-5.8°C) in the next century, with substantial regional variation. Soil moisture is likely to decline in many regions, and intense rainstorms are likely to become more frequent. Rising temperatures could have four major impacts on plants and animals: (1) timing of ecological events; (2) geographic range; (3) species' composition within communities; and (4) ecosystem processes, such as carbon cycling and storage (Parmesan, 2006). Local Effects of Climate Change While the above discussion identifies the possible effects of climate change at a global and potentially statewide level, current scientific modeling tools are unable to predict with a similar degree of accuracy what local impacts may occur with a similar degree of accuracy. In general, regional and local predictions are made based on downscaling statewide models (CalEPA, April r City of Carlsbad 6 C • C e • C C C C C • • • e • C • ., & C C • e C ., • e • C e C • • e • C • C • e • • • Legoland Hotel Project Greenhouse Gas Study 2010) . Regulatory Setting The following regulations address both climate change and GHG emissions. International Regulations The United States is, and has been, a participant in the United Nations Framework Convention on Climate Change (UNFCCq since it was produced in 1992. The UNFCCC is an international environmental treaty with the objective of, "stabilization of GHG concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system." This is generally understood to be achieved by stabilizing global GHG concentrations between 350 and 400 ppm, in order to limit the global average temperature increases between 2 and 2.4°C above pre-industrial levels (IPCC, 2007). The UNFCCC itself does not set limits on GHG emissions for individual countries or enforcement mechanisms. Instead, the treaty provides for updates, called "protocols," that would identify mandatory emissions limits . Five years later, the UNFCCC brought nations together again to draft the Kyoto Protocol (1997). The Kyoto Protocol established commitments for industrialized nations to reduce their collective emissions of six GHGs (CO2, ~ N2O, SF6, HFCs, and PFCs) to 5.2 percent below 1990 levels by 2012. The United States is a signatory of the Kyoto Protocol, but Congress has not ratified it and the United States has not bound itself to the Protocol's commitments (UNFCCC, 2007). The first commitment period of the Kyoto Protocol ended in 2012. Governments, including 38 industrialized countries, agreed to a second commitment period of the Kyoto Protocol beginning January 1, 2013 and ending either on December 31, 2017 or December 31, 2020, to be decided by the Ad Hoc Working Group on Further Commitments for Annex I Parties under the Kyoto Protocol at its seventeenth session (UNFCCC, 2011) . In Durban (17th session of the Conference of the Parties in Durban, South Africa, 2011), governments decided to adopt a universal legal agreement on climate change. Work began on that task immediately under a new group called the Ad Hoc Working Group on the Durban Platform for Enhanced Action. Progress was also made regarding the creation of a Green Climate Fund (GCF) for which a management framework was adopted (UNFCCC, 2011; United Nations, 2011). In December 2015, the 21st session of the Conference of the Parties (COP21) adopted the Paris Agreement. The deal requires all countries that ratify it to commit to cutting greenhouse gas emissions, with the goal of peaking greenhouse gas emissions "as soon as possible" (Worland, 2015). The agreement includes commitments to (1) achieve a balance between sources and sinks of greenhouse gases in the second half of this century; (2) to keep global temperature increase "well below" 2 degrees Celsius (q or 3.6 degrees Fahrenheit (F) and to pursue efforts to limit it to 1.5 C; (3) to review progress every five years; and (4) to spend $100 billion a year in climate finance for developing countries by 2020 (UNFCCC, 2015). The agreement includes both legally binding measures, like reporting requirements, as well as voluntary or non-binding measures while, such as the setting of emissions targets for any individual country (Worland, 2015) . r City of Carlsbad 7 C • e e • C e C C e C • • C • e • ., • e e • • • e • e • C C C • • e • IJ • C • e • • • Legoland Hotel Project Greenhouse Gas Study Federal Regulations The United States Supreme Court in Massachusetts et al. v. Environmental Protection Agency et al. ([2007] 549 U.S. 05-1120) held that the U.S. EPA has the authority to regulate motor-vehicle GHG emissions under the federal Clean Air Act. The U.S. EPA issued a Final Rule for mandatory reporting of GHG emissions in October 2009. This Final Rule applies to fossil fuel suppliers, industrial gas suppliers, direct GHG emitters, and manufacturers of heavy-duty and off-road vehicles and vehicle engines, and requires annual reporting of emissions. The first annual reports for these sources were due in March 2011 . On May 13, 2010, the U.S. EPA issued a Final Rule that took effect on January 2, 2011, setting a threshold of 75,000 tons C02e per year for GHG emissions. New and existing industrial facilities that meet or exceed that threshold will require a permit after that date. On November 10, 2010, the U.S. EPA published the "PSD and Title V Permitting Guidance for Greenhouse Gases." The U.S. EPA's guidance document is directed at state agencies responsible for air pollution permits under the Federal Clean Air Act to help them understand how to implement GHG reduction requirements while mitigating costs for industry. It is expected that most states will use the U.S . EPA' s new guidelines when processing new air pollution permits for power plants, oil refineries, cement manufacturing, and other large pollution point sources. On January 2, 2011, the U.S. EPA implemented the first phase of the Tailoring Rule for GHG emissions Title V Permitting. Under the first phase of the Tailoring Rule, all new sources of emissions are subject to GHG Title V permitting if they are otherwise subject to Title V for another air pollutant and they emit at least 75,000 tons C02e per year. Under Phase 1, no sources were required to obtain a Title V permit solely due to GHG emissions. Phase 2 of the Tailoring Rule went into effect July 1, 2011. At that time new sources were subject to GHG Title V permitting if the source emits 100,000 tons C02e per year, or they are otherwise subject to Title V permitting for another pollutant and emit at least 75,000 tons C02e per year . On July 3, 2012 the U.S. EPA issued the final rule that retains the GHG permitting thresholds that were established in Phases 1 and 2 of the GHG Tailoring Rule. These emission thresholds determine when Oean Air Act permits under the New Source Review Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs are required for new and existing industrial facilities. California Regulations California Air Resources Board is responsible for the coordination and oversight of State and local air pollution control programs in California. California has a numerous regulations aimed at reducing the state's GHG emissions. These initiatives are summarized below . Assembly Bill (AB) 1493 (2002), California's Advanced Clean Cars program (referred to as "Pavley"), requires ARB to develop and adopt regulations to achieve "the maximum feasible and cost-effective reduction of GHG emissions from motor vehicles." On June 30, 2009, U.S. EPA granted the waiver of Clean Air Act preemption to California for its greenhouse gas emission standards for motor vehicles beginning with the 2009 model year. Pavley I took effect for model years starting in 2009 to 2016 and Pavley II, which is now referred to as "LEV (Low r City of Carlsbad 8 C • C C • C t C e • C e • e • C • • • C e • C • e • e • C e C • • e • C C C • • • • • Legoland Hotel Project Greenhouse Gas Study Emission Vehicle) III GHG" will cover 2017 to 2025. Fleet average emission standards would reach 22 percent reduction from 2009 levels by 2012 and 30 percent by 2016. The Advanced Clean Cars program coordinates the goals of the Low Emissions Vehicles (LEV), Zero Emissions Vehicles (ZEV), and Clean Fuels Outlet programs and would provide major reductions in GHG emissions. By 2025, when the rules will be fully implemented, new automobiles will emit 34 percent fewer GHGs and 75 percent fewer smog-forming emissions from their model year 2016 levels (ARB, 2011). In 2005, former Governor Schwarzenegger issued Executive Order (EO) S-3-05, establishing statewide GHG emissions reduction targets. EO S-3-05 provides that by 2010, emissions shall be reduced to 2000 levels; by 2020, emissions shall be reduced to 1990 levels; and by 2050, emissions shall be reduced to 80 percent below 1990 levels (CalEPA, 2006). In response to EO S-3-05, CalEP A created the Climate Action Team (CAT), which in March 2006 published the Climate Action Team Report (the "2006 CAT Report") (CalEPA, 2006). The 2006 CAT Report identified a recommended list of strategies that the state could pursue to reduce GHG emissions. These are strategies that could be implemented by various state agencies to ensure that the emission reduction targets in EO S-3-05 are met and can be met with existing authority of the state agencies. The strategies include the reduction of passenger and light duty truck emissions, the reduction of idling times for diesel trucks, an overhaul of shipping technology/ infrastructure, increased use of alternative fuels, increased recycling, and landfill methane capture, etc. In April 2015 Governor Brown issued EO B-30-15, calling for a new target of 40% below 1990 levels by 2030. California's major initiative for reducing GHG emissions is outlined in Assembly Bill 32 (AB 32), the "California Global Warming Solutions Act of 2006," signed into law in 2006. AB 32 codifies the statewide goal of reducing GHG emissions to 1990 levels by 2020 (essentially a 15 percent reduction below 2005 emission levels; the same requirement as under S-3-05), and requires ARB to prepare a Scoping Plan that outlines the main State strategies for reducing GHGs to meet the 2020 deadline. In addition, AB 32 requires ARB to adopt regulations to require reporting and verification of statewide GHG emissions . After completing a comprehensive review and update process, ARB approved a 1990 statewide GHG level and 2020 limit of 427 MMT COie. The Scoping Plan was approved by ARB on December 11, 2008, and included measures to address GHG emission reduction strategies related to energy efficiency, water use, and recycling and solid waste, among other measures. Many of the GHG reduction measures included in the Scoping Plan (e.g., Low Carbon Fuel Standard, Advanced Oean Car standards, and Cap-and-Trade) have been adopted over the last five years. Implementation activities are ongoing and ARB is currently the process of updating the Scoping Plan . In May 2014, ARB approved the first update to the AB 32 Scoping Plan. The 2013 Scoping Plan update defines ARB' s climate change priorities for the next five years and sets the groundwork to reach post-2020 goals set forth in EO S-3-05. The update highlights California's progress toward meeting the "near-term" 2020 GHG emission reduction goals defined in the original Scoping Plan.

The adopted guidelines give lead agencies the discretion to set quantitative or qualitative thresholds for the assessment and mitigation of GHGs and climate change impacts. ARB Resolution 07-54 establishes 25,000 MT of GHG emissions as the threshold for identifying the largest stationary emission sources in California for purposes of requiring the annual reporting of emissions. This threshold is just over 0.005 percent of California's total inventory of GHG emissions for 2004 . Senate Bill (SB) 375, signed in August 2008, enhances the state's ability to reach AB 32 goals by directing ARB to develop regional GHG emission reduction targets to be achieved from passenger vehicles for 2020 and 2035. In addition, SB 375 directs each of the state's 18 major Metropolitan Planning Organizations (MPO) to prepare a "sustainable communities strategy" (SCS) that contains a growth strategy to meet these emission targets for inclusion in the Regional Transportation Plan (RTP). On September 23, 2010, ARB adopted final regional targets for reducing GHG emissions from 2005 levels by 2020 and 2035. The San Diego Association of Governments (SANDAG) was assigned GHG emission targets of a 7% reduction in GHGs from transportation sources from 2005 levels by 2020 and a 13 % reduction in GHGs from transportation sources from 2005 levels by 2035 . Renewables Portfolio Standards (RPS) pursuant to SB 1038, SB 1078, SB 1250, and SB 107 requires retail sellers of electricity to increase the amount of renewable energy they procure each year by at least 1 percent until 20 percent of their retail sales are served with renewable energy. • Senate Bill 1038 (Chapter 515, Statutes of 2002). The pertinent provisions of SB 1038 were formerly codified in Public Utilities Code Sections 383.5 and 445, but are now codified in Public Resources Code Sections 25740 through 25751 as a result of Senate Bill 183 (Chapter 666, Statutes of 2003). • Senate Bill 1078; Chapter 516, Statutes of 2002.

SF6 gas is commonly used as an arc quenching and insulating medium for high and medium voltage switchgear systems used in electrical substations. The regulation requires owners of such switchgear to: (1) annually report their SF6 r City of Carlsbad 10 C e C • e C e C C • e • • C • e • • • C • • C e C • I) • e e C • • I> • • e C • • • • • Legoland Hotel Project Greenhouse Gas Study emissions; (2) determine the emission rate relative to the SF6 capacity of the switchgear; (3) provide a complete inventory of all gas-insulated switchgear and their SF6 capacities; (4) produce a SF6 gas container inventory; and (5) keep all information current for ARB enforcement staff inspection and verification. Changes to the switching station owned by PG&E and any gas insulated switchgear associated with the project would be subject to this regulation. In April 2011, Governor Brown signed SB 2X requiring California to generate 33 percent of its electricity from renewable energy by 2020 . On April 29, 2015, Governor Brown issued an executive order B-30-15 to establish a statewide mid-term GHG reduction target of 40 percent below 1990 levels by 2030. According to CARB, reducing GHG emissions by 40 percent below 1990 levels in 2030 ensures that California will continue its efforts to reduce carbon pollution and help to achieve federal health-based air quality standards. Setting clear targets beyond 2020 also provides market certainty to foster investment and growth in a wide array of industries throughout the State, including clean technology and clean energy. CARB is currently working to update the Scoping Plan to provide a framework for achieving the 2030 target. The updated Scoping Plan is expected to be completed and adopted by CARB in 2016 (CARB 2015) .

California Environmental Quality Act Pursuant to the requirements of SB 97, the Resources Agency has adopted amendments to the State CEQA Guidelines for the feasible mitigation of GHG emissions or the effects of GHG emissions. The adopted CEQA Guidelines provide general regulatory guidance on the analysis and mitigation of GHG emissions in CEQA documents, while giving lead agencies the discretion to set quantitative or qualitative thresholds for the assessment and mitigation of GHGs and climate change impacts. To date, a variety of air districts have adopted quantitative significance thresholds for GHGs . Local Regulations The City of Carlsbad adopted its Climate Action Plan (CAP), in September 2015. The CAP outlines the city's goals for GHG reduction which are consistent with current statewide regulations. By calculating a "modified baseline forecast" the City can compare the expected emissions in 2020 and beyond to the Sate mandated emissions targets. The modified baseline is the Cities current emissions adjusted to include both population growth and State reductions . The difference between the modified baseline and the emissions target is referred to as the emissions gap. The CAP has been enacted to eliminate this gap and thus meet the requirements of AB32. The following table summarizes the City of Carlsbad's projected emissions gaps . r City of Carlsbad 11 C e C e e C C C C • • • • C • • • C • C • • e C C • • • C C C • • C • e C C • • e • • Legoland Hotel Project Greenhouse Gas Study Table 1 City of Carlsbad's Projected Emissions Gaps Year Total Modified Baseline GHG Emissions Targets (MT C02e) 2020 473,082 535,763 2025 467,018 464,328 2030 452,762 392,893 2035 455,556 321,458 Emissions "Gap" Target Met 2,690 59,869 134,098 As shown in the table, under the assumptions of the "total modified baseline" the City is projected to meet the requirements of AB32. However, although there is no current mandatory legislation extending past 2020, further State mandated reductions are probable in the future . Therefore, the City has scaled the goals of AB32 in a linear fashion to approximate future CHG emission targets. The CAP has been implemented to help the City meet these goals . The emphasis of the CAP is on municipal facilities and operations followed by programs to reduce emissions in the community. However, the CAP also includes a project level screening threshold of 900 MT of CO2e. Projects which have projected emissions over 900 MT need to complete the CAP project checklist and show compliance with the goals of the CAP. CLIMATE CHANGE IMPACT ANALYSIS Significance Thresholds The State CEQA Guidelines are used in evaluating the cumulative significance of CHG emissions from the proposed project. As described by CEQA Guidelines Section 15064.4, a lead agency shall have discretion to determine, in the context of a particular project, whether to: (1) Use a model or methodology to quantify greenhouse gas emissions resulting from a project, and which model or methodology to use. The lead agency has discretion to select the model or methodology it considers most apprapriate provided it supports its decision with substantial evidence. The lead agency should explain the limitations of the particular model or methodology selected for use; and/or (2) Rely on a qualitative analysis or performance based standards. Further, a lead agency should consider the following factors, among others, when assessing the significance of impacts from CHG emissions on the environment: (1) The extent to which the project may increase or reduce greenhouse gas 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 adapted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gas emissions. Such requirements must be adapted by the relevant public agency through a public review process and must reduce or mitigate the project's incremental contribution of r City of Carlsbad 12 e C C e e C e • C C • • • C • C • e • C • e e e e • • • C C C • • • • • C C • e e • • Legoland Hotel Project Greenhouse Gas Study GHG emissions. If there is substantial evidence that the possible effects of a particular project are still cumulatively considerable notwithstanding compliance with the adopted regulations or requirements, an EIR must be prepared for the project. The majority of individual projects do not generate sufficient GHG emissions to create a project- specific impact through a direct influence to global climate change; therefore, the issue of climate change typically involves an analysis of whether a project's contribution towards an impact is cumulatively considerable. "Cumulatively considerable" means that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, other current projects, and probable future projects (CEQA Guidelines, Section 15355) . The adopted CEQA Guidelines provide regulatory guidance on the analysis and mitigation of GHG emissions in CEQA documents, while giving lead agencies the discretion to set quantitative or qualitative thresholds for the assessment and mitigation of GHGs and climate change impacts. The City of Carlsbad has determined that a project that emits over 900 MT would be less than significant if that project conforms to the goals of the Climate Action Plan . Because the project is anticipated to emit over 900 MT of CO2e, it would be considered less than significant if the project can show consistency with the Climate Action Plan. Methodology This analysis is based on the methodologies recommended by the California Air Pollution Control Officers Association [CAPCOA] 0anuary 2008) CEQA and Climate Change white paper. The analysis focuses on COi, N2O, and 0-L as these are the GHG emissions that onsite development would generate in the largest quantities. Fluorinated gases, such as HFCs, PFCs, and SF6, were also considered for the analysis. However, the project is a hotel development; therefore, the quantity of fluorinated gases would not be significant since fluorinated gases are primarily associated with industrial processes. Calculations were based on the methodologies discussed in the CAPCOA white paper 0anuary 2008) and included the use of the California Climate Action Registry General Reporting Protocol 0anuary 2009) . This analysis calculates GHG emissions by quantifying the project's amenities and design features and also takes into account current state and federal measures that are intended to reduce GHG emissions. State and federal measures that are built into the emissions model calculation include Title 24 Energy Standards, Pavley (Clean Car Standards) and Low Carbon Fuel Standards. Construction Emissions Construction of the proposed project would generate GHG emissions, primarily due to the operation of construction equipment and truck trips. Project construction was estimated to be completed within approximately 15 months. For this analysis, it was assumed that construction would commence in January 2017 and would be completed in March of 2018. Emissions associated with the construction period were estimated using the California Emissions Estimator Model (CalEEMod), based on the projected maximum amount of equipment that would be used onsite at one time. Complete CalEEMod results and assumptions can be viewed in the Appendix . r City of Carlsbad 13 • • C C • C e C" e • • • • e • C • C • C e e C e C • • • C e C e • • • • C C e e • • e Legoland Hotel Project Greenhouse Gas Study Although construction activity is addressed in this analysis, CAPCOA does not discuss whether any of the suggested threshold approaches (as discussed below in GHG Cumulative Significance) adequately address impacts from temporary construction activity. As stated in the CEQA and Climate Ozange white paper, "more study is needed to make this assessment or to develop separate thresholds for construction activity" (CAPCOA, 2008). Nevertheless, the SCAQMD has recommended amortizing construction-related emissions over a 30-year period in conjunction with the proposed project's operational emissions. Indirect Emissions Emissions associated with area sources, including consumer products, landscape maintenance, hearth, and architectural coating were calculated in CalEEMod and utilize standard emission rates from CARB, USEPA, and district supplied emission factor values (CalEEMod User Guide, 2011). Operational emissions from electricity and natural gas use at the proposed project were estimated using CalEEMod (see Appendix for calculations). The default values on which CalEEMod are based include the California Energy Commission (CEC) sponsored California Commercial End Use Survey (CEUS) and Residential Appliance Saturation Survey (RASS) studies. CalEEMod provides operational emissions of C(n, N2O, and Q-L. This methodology is considered reasonable and reliable for use, as it has been subjected to peer review by numerous public and private stakeholders, and in particular by the CEC. It is also recommended by CAPCOA Oanuary 2008). Emissions from waste generation were also calculated in CalEEMod and are based on the IPCC s methods for quantifying GHG emissions from solid waste using the degradable organic content of waste (CalEEMod User Guide, 2011). Waste disposal rates by land use and overall composition of municipal solid waste in California was primarily based on data provided by the California Department of Resources Recycling and Recovery (CalRecycle). Emissions from water and wastewater usage calculated in CalEEMod were based on the default electricity intensity is from the CECs 2006 Refining Estimates of Water-Related Energy Use in California using the average values for Northern and Southern California . Direct Emissions from Mobile Combustion Emissions of COi and G-L from transportation sources were quantified using CalEEMod. Because CalEEMod does not calculate N2O emissions from mobile sources, N2O emissions were quantified using the California Climate Action Registry General Reporting Protocol Oanuary, 2009) direct emissions factors for mobile combustion (see Appendix for calculations). The calculation methodology used is consistent with, but more conservative than, The Climate Registry (March, 2013). Vehicle trips were estimated in CalEEMod using the default settings for a 250 unit hotel. Emission rates for N2O emissions were based on the vehicle mix output generated by CalEEMod and the emission factors found in the California Climate Action Registry General Reporting Protocol. One of the limitations to a quantitative analysis is that emission models, such as CalEEMod, evaluate aggregate emissions and do not demonstrate, with respect to a global impact, what proportion of these emissions are "new" emissions, specifically attributable to the project in question. For most projects, the main contribution of GHG emissions is from motor vehicles and r City of Carlsbad 14 e e C C e C e C • • C • • e C C • • • e e e C C C • • • C C C e • • • • C C • • • • • Legoland Hotel Project Greenhouse Gas Study the total vehicle miles traveled (VMT), but the quantity of these emissions appropriately characterized as "new'' is uncertain. Traffic associated with a project may be relocated trips from other locales, and consequently, may result in either higher or lower net VMT. For the proposed project analyzed in this report, it is likely that some of the GHG emissions associated with traffic and energy demand would be truly "new" emissions. However, it is also likely that some of the emissions represent diversion of emissions from other locations. Thus, although GHG emissions are associated with onsite development, it is not possible to discern how much diversion is occurring or what fraction of those emissions represents global increases. In the absence of information regarding the different types of trips, the VMT estimate generated by CalEEMod, which assumes that all trips are new, is used as a conservative, "worst-case" estimate . Project Impacts The following summarizes the proposed project and compares calculated emissions to the City of Carlsbad's Climate Action Plan and the established threshold of 900 MT of CO2e (see Appendix for full CalEEMod worksheets). Construction Emissions Construction activity is assumed to occur over a period of approximately 15 months. Based on CalEEMod results, construction activity for the project would generate an estimated 657.4 metric tons of COie (as shown in Table 2). Amortized over a 30-year period (the assumed life of the project), construction of the proposed project would generate about 22 metric tons of COie per year. Table 2 Estimated Construction Emissions of Greenhouse Gases Amortized Over A 30-Year Period Annual Emissions Year (Carbon Dioxide Equivalent (C02e) 2017 584.7 metric tons 2018 72.8 metric tons Total 657 .4 metric tons Amortized over 30 years 21.9 metric tons per year See Appendix for Ca/EEMod Results. Operational Emissions Operational emissions include GHG emissions from area source, energy use, waste, water, and transportation. Each of these operational emission sources is discussed below . Area Source Emissions The CalEEMod model was used to calculate direct sources of air emissions located at the project site. This includes hearths/fireplaces, consumer product use, and landscape maintenance equipment. Emissions associated with consumer products and landscaping equipment were found to be 0.005 metric tons of CO2e per year . ,, City of Carlsbad 15 C • C e e C e e C e C C C e e C e C • C • e C e e • & • • • e e • C • e C e e • • • • Legoland Hotel Project Greenhouse Gas Study Energy Use The default setting in the CalEEMod output assumes that the operation of the onsite development would consume both electricity and natural gas (see Appendix for calculations). The generation of electricity through combustion of fossil fuels yields COi, and to a smaller extent, N2O and ~-As discussed above, annual electricity and natural gas emissions have been calculated using default values from the CEC sponsored CEUS and RASS studies which are built into CalEEMod. The current CalEEMod version assumes all structures will be built to 2008 Title 24 standards. In order to avoid over estimating the reductions due to compliance with Title 24, a 25% improvement over 2008 Title 24 was credited to both the unmitigated and the mitigated scenario. This is because the California Energy Commission estimates Title 24 2013 is approximately 25% more efficient than 2008 Title 24. Using these variables, the unmitigated project is expected to emit approximately 2,506 MT of CO2e per year due to electricity and natural gas consumption. Solid Waste Emissions It was assumed that the project would divert 50% of the waste due to City of Carlsbad recycling policies. The estimated emissions associated with waste generation were found to be 31 MT of CO2e . Water Use Emissions The project would use approximately 7.0 million gallons of water per year. Based on the amount of electricity generated in order to supply this amount of water, as shown in Table 3, the project would generate approximately 38 metric tons of CO2e per year. Transportation Emissions Mobile source GHG emissions were estimated using the average daily trips derived from the traffic analysis prepared by STC Traffic, Inc. and by the total vehicle miles traveled (VMT) estimated in CalEEMod. Based on the CalEEMod estimate, onsite development would generate an estimated 3,799,862 annual VMT . Table 3 shows the estimated mobile emissions of GHGs for the project based on the estimated annual VMT. As noted above, CalEEMod does not calculate N2O emissions related to mobile sources. As such, N2O emissions were calculated based on the project's VMT using calculation methods provided by the California Climate Action Registry General Reporting Protocol Oanuary, 2009). The project would generate about 1,842 metric tons of COze units associated with mobile emissions . Combined Construction, Stationary and Mobile Source Emissions Table 3 combines the construction, operational and mobile GHG emissions associated with onsite development for the proposed project. Emissions associated with construction activity (approximately 657 metric tons COze) are amortized over the anticipated 30-year life of the project. As is shown in the table below, emissions for the project are estimated to be 4,439 MT of COze, exceeding the 900 MT of COze screening threshold. Therefore, the project is required to show compliance with the goals stated in the City of Carlsbad CAP. r City of Carlsbad 16 C C e C) e e C C C e e C e C C C • C • e e • C C C • e • e C C e C C • • C C C C • • e Legoland Hotel Project Greenhouse Gas Study Table 3 Combined Annual Emissions of Greenhouse Gases Emission Source Annual GHG Emissions MT of C02e/year Construction 21.9 (amortized over 30 years) Operational Area 0 Energy 2,506 Solid Waste 31 Water 38 Mobile C02andCH4 1,759 N20 83 Total 4,439 Sources: See Appendix for calculations and for GHG emission factor assumptions. Note: All numbers may not add due to rounding . Emissions Reductions Strategies As discussed above, the City of Carlsbad adopted its CAP in September, 2015. The goal of the CAP is to reduce the City's GHG emissions to 15% below 2005 levels by 2020, and prepare for more stringent GHG reduction goals implemented in the future. The CAP has established that new development projects emitting less than 900 MT of C02e annually would not contribute considerably to cumulative climate change impacts, and therefore, do not need to demonstrate consistency with the CAP. Projects that generate emissions above the 900 MT screening threshold must prove compliance with the CAP by completing a project review checklist or through a self-developed program approach. At the time of this study the City has not developed a final checklist. Therefore, in compliance with the CAP and City guidance, projects that exceed the GHG emission screening threshold must prove compliance with the CAP by detailing the applicable sustainability initiatives that the project would include that will lead to reductions in project-level GHGs and quantify those reductions. As shown in Table 3, the proposed project's annual GHG emissions would exceed the 900 annual MT screening threshold. Therefore, the project applicant has developed a project specific GHG emissions reduction program (Table 4) that details the proposed project's consistency with the stated goals of the CAP and the project's applicability with those goals. r City of Carlsbad 17 C e C C e C C e • e C C e e e e e C • e • • e C e e C e • e • e C C • e C C C C • • e Legoland Hotel Project Greenhouse Gas Study Table4 C . t ons1s ency with Applicable Climate Action Plan Reduction Measures GHG Reduction Measures Project Applicability Promote commercial and city facility Implement 3rd party "enhanced" commissioning, or improving building operations commissioning.

Parking Reduction The project will reduce parking spaces resulting in a 6% decrease in VMT. Promote commercial and city facility commissioning, or improving building operations The project will implement advanced commissioning of the completed facility to ensure that all HV AC systems and lighting controls are functioning as intended. Commissioning of large buildings such as hotels has been shown to reduce overall energy consumption by as much as 13% in new buildings (Evan Mills. 2009). Implementation of Green Building Code The project will follow all requirements laid out by Title 24. Title 24 requires buildings meet strict guidelines for water conservation, construction waste diversion, and energy efficiency. Compliance with Title 24 is mandatory and has been included in the City's "modified baseline". Replace Incandescent bulbs with light emitting diodes (LED) bulbs The proposed project would utilize LED lighting throughout in order to reduce both electricity consumption and cooling loads. Because LED's use up to 55% less electricity than comparable standard bulbs, they also significantly reduce the heat produced and therefore, the cooling loads of the building. Promote Transportation Demand Management The project will implement a rigorous transportation demand management plan. The plan will provide incentives for employees to use alternative transportation methods other than single occupancy vehicles which will in turn reduce overall VMT and associated emissions. The following TOM methods will be implemented at the site: • Employee carpool parking spaces close to theme park entrance • Shuttle service between local hotels and LEGOLAND • School bus drop-off and parking area near theme park entrance • Pedestrian entrance from Grand Pacific Resort, and private entrance from Sheraton Carlsbad • Subsidized meals for employees to discourage trips to restaurants • Free meals to employees on holidays and busiest days of the year • Bike racks, lockers and showers for employees • On-site services for existing hotel guests (restaurants, rental car services, concierge services); Increase zero-emissions vehicle travel Provisions will be included in the plan to allow for the installation of electric vehicle charging stations as demand from guests increases. r City of Carlsbad 19 e e C e C e e C e e e e C C C e • • e • e e C C • e e e • • • • e e C • • • • • • • • Legoland Hotel Project Greenhouse Gas Study Reduce the GHG intensity of water supply conveyance, treatment and delivery The project will reduce GHG emissions associated with water use by utilizing high efficiency fixtures, low water use irrigation, and no irrigation artificial turf where applicable. Reducing the amount of water consumed will reduce GHG emissions associated with transporting, cleaning, and finally treating wastewater. Furthermore, the facility will utilize recycled water for irrigation as allowable by code. Utilize public transportation The project is located within close proximity (0.01 miles) to public transportation. This siting allows park visitors to take public transit instead of driving their own vehicles and therefore reducing overall VMT and emissions. Increase diversity The project will provide 250 hotel rooms in close proximity to the existing Legoland resort. Visitors to the park will be able to stay at these hotels rather than hotels located farther from the resort and therefore reduce the number of trips required daily. This close proximity reduces the projects overall VMT and associated emissions . Urban Infill The project will be located on an existing parking lot. Infill development helps increase density, protect greenspace, and reduce VMT . Parking Reduction The project will be built on top of an existing parking lot and will result in a net reduction of 640 parking spaces. Therefore, it is assumed the project will have a 6 % trip reduction due to a decrease in parking spaces. Mitigated Project Emissions The estimated mitigated emissions for the project were run using CalEEmod. The following mitigation measures were taken into account using the model: • 25 % water use reduction • LED lighting • Optional transportation demand management plans open to 100% of employees • Increased diversity • Parking reductions • Distance to public transportation • Assumed 50% waste diversion Some reduction measures such as building commissioning and future electric charging stations were not included in the assessment. However, these attributes are expected to further decrease emissions. Furthermore, compliance with current Title 24 was applied to both the unmitigated and mitigated scenario due to the fact that the CalEEMod only includes 2008 Title 24 as a default. Table 5 shows the estimated GHG emissions associated with the project after the inclusion of the above described mitigation measures . r City of Carlsbad 20 • e C C C e • C C r- e C C C e C • e C I) C C C C e e e e C; • C e C • e e C • C) • • • • Legoland Hotel Project Greenhouse Gas Study Table 5 Combined Annual Emissions of Greenhouse Gases Emission Source Annual GHG Emissions MT of C02e/year Construction 21.9 (amortized over 30 years) Operational Area 0 Energy 2,204 Solid Waste 31 Water 36 Mobile C02andCH4 1,119 N20 51 Total 3,463 Sources: See Appendix for calculations and for GHG emission factor assumptions. Note: All numbers may not add due to rounding. The projects greenhouse gas mitigation measures would reduce overall emissions from an estimated 4,439 MT of C02e to an estimated 3,463 MT of C02e. This represents a reduction of 976 MT of C02e or approximately 22%. A majority of these emissions were saved through a reduction of 1,442,281 vehicle miles traveled. VMT reduction was achieved through the location of the project, a reduction in parking spaces, and an optional transportation demand management program for employees. Additional reductions were achieved through a reduction in water use (5%) and implementation of energy saving technologies such as LED lighting (12 % ) . Additional reductions from building commissioning are expected to result in an additional 13 % decrease in building energy consumption. By reducing GHG emissions through a variety of techniques including TDM, LED lighting, site selection, and water efficiency, the proposed project has shown compliance with the emissions reductions goals outlined in the CAP and the draft CAP checklist. By complying with all State ordinances such as Title 24, the project has shown that it will not detract from the City of Carlsbad's ability to meet the goals set forth by AB32. Furthermore, the project has included additional GHG reduction measures which will help further the goals of the City as they continue to work towards post 2020 emissions reductions. Therefore, the project is expected to have a less than significant impact . r City of Carlsbad 21 e ,,,,. -C • C C t..: C C ..
