The Intergovernmental Panel on Climate Change (IPCC) has identified four <br />major GHGs—water vapor, carbon dioxide (CO2), methane (CH4), and ozone (03)—that are the likely cause <br />of an increase in global average temperatures observed within the 20th and 21st centuries. Other GHG <br />identified by the IPCC that contribute to global warming to a lesser extent include nitrous oxide (N2O), sulfur <br />hexafluoride (SF6), hydrofluorocarbons, perfluorocarbons, and chloroflumocarbons.t, 2 <br />This section analyzes the project's contribution to global climate change impacts in California through an <br />analysis of projectrelatedGHG emissions. Information on manufacture of cement, steel, and other "life cycle" <br />emissions that would occur as a result of the project are not applicable and are not included in this analysis. A <br />background discussion on the GHG regulatory setting and GHG modeling can be found in Appendix A to <br />this Initial Study. <br />Would the project: <br />a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant <br />impact on the environment? <br />Less Than Significant Impact. Global climate change is not confined to a particular project area and is <br />generally accepted as the consequence of global industrialization over the last 200 years. A typical project, even <br />a very large one, does not generate enough greenhouse gas emissions on its own to influence global climate <br />change significantly; hence, the issue of global climate change is by definition a cumulative environmental <br />impact. <br />The replacement parks would not result in a substantial increase in water use, wastewater and solid waste <br />generation, area sources (e.g., consumer cleaning products), and energy usage (i.e., natural gas and electricity) <br />(see also Section 3.18, Utiblies and Service Syrtews). Additionally, the proposed project would generate less than <br />two daily trips (see Section 3.16, Tranrpartatian/Trafc). Consequently, the project operational- and construction <br />related GHG emissions would be nominal and would not exceed SCAQMD's brightlinesignificance threshold. <br />Therefore, GHG emissions impacts are less than significant. <br />b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the <br />emissions of greenhouse gases? <br />Less Than Significant Impact. Applicable plans adopted for the purpose of reducing GHG emissions <br />include the California Air Resources Board's (CARB) Scoping Plan, the SCAG's Regional Transportation <br />Water vapor (H20) is the strongest GHG and the most variable in its phases (vapor, cloud droplets, ice crystals). However, water <br />vapor is not considered a pollutant, but part of the feedback loop rather than a primary cause of change. <br />Black carbon contributes to climate change both directly, by absorbing sunlight, and indirectly, by depositing on snow (making it <br />melt faster) and by interacting with clouds and affecting cloud formation. Black carbon is the most strongly light -absorbing <br />component of PM emitted from burning fuels. Reducing black carbon emissions globally can have immediate economic, climate, <br />and public health benefits. California has been an international leader in reducing emissions of black carbon, with close to 95 percent <br />control expected by 2020 due to existing programs that target reducing PM from diesel engines and burning activities (GARB 2017b). <br />However, state and national GHG inventories do not yet include black carbon due to ongoing work resolving the precise global <br />warming potential of black carbon. Guidance for CEQA documents does not yet include black carbon. <br />75C-93 <br />
