leading to a trend of unnatural warming of the earth's climate, known as global climate <br />change or global warming." <br />This section includes an estimated quantification of the following GHG emissions associated <br />with the proposed project: <br />• Carbon Dioxide (CO2) <br />• Nitrous Oxide (N20) <br />• Methane (CH4) <br />The projected GHG emissions are provided on an average annual basis using the CO2 <br />equivalent (CO2e) and include the proposer's best estimate of average annual emissions over <br />the proposed life/design service life of the project. Emissions were estimated using the US <br />Environmental Protection Agency's Simplified GHG Emissions Calculator (Version 7 June <br />2021)12 and are summarized in Appendix D and Table 10 and Table 11 by project phase (i.e., <br />construction and operations) and source type (e.g., combustion from mobile equipment, off - <br />site electricity (see Appendix D for background analysis). <br />Construction emissions are based on length of construction and are from mobile equipment <br />including passenger cars, light -duty trucks, medium and heavy-duty trucks, and construction <br />equipment (both gasoline and diesel). Emissions associated with construction materials were <br />not analyzed, as these are outside the scope of this analysis. <br />Emissions from cooling and refrigeration systems are not accounted for in this operational <br />emissions analysis as GHGs from refrigerants are approximately less than 5 percent of the <br />total GHG emissions of a building.13 The project does not include any owned or leased <br />vehicles anticipated to be used by the organization during operation, plans to purchase <br />gases during operation, or land use conversions. <br />Table 10: Existing Operational Emissions <br />Table 17: Construction Emissions <br />11 Summarized from U.S. EPA, Overview of Greenhouse Gases: https://www.epa.gov/ghgemissions/overview- <br />greenhouse-gases <br />12 Source: https://www.epa.gov/climateleadership/simplified-ghg-emissions-calculator <br />"Source: https://practicegreenhealth.org/sites/default/files/2019-06/PracticeGreenhealth GHG Toolkit O.pdf <br />" Based on calculations from CalRecycle's website titled "Estimated Solid Waste Generation Rates," available at <br />https://www2.calrec cl�govlwastecharacterization/general/rates. <br />Haviland Fields EAW 25 September 2023 <br />
