leading to a trend of unnatural warming of the earth's climate, known as global climate change or global warming." This section includes an estimated quantification of the following GHG emissions associated with the proposed project: • Carbon Dioxide (CO2) • Nitrous Oxide (N20) • Methane (CH4) The projected GHG emissions are provided on an average annual basis using the CO2 equivalent (CO2e) and include the proposer's best estimate of average annual emissions over the proposed life/design service life of the project. Emissions were estimated using the US Environmental Protection Agency's Simplified GHG Emissions Calculator (Version 7 June 2021)12 and are summarized in Appendix D and Table 10 and Table 11 by project phase (i.e., construction and operations) and source type (e.g., combustion from mobile equipment, off- site electricity (see Appendix D for background analysis). Construction emissions are based on length of construction and are from mobile equipment including passenger cars, light-duty trucks, medium and heavy-duty trucks, and construction equipment (both gasoline and diesel). Emissions associated with construction materials were not analyzed, as these are outside the scope of this analysis. Emissions from cooling and refrigeration systems are not accounted for in this operational emissions analysis as GHGs from refrigerants are approximately less than 5 percent of the total GHG emissions of a building.13 The project does not include any owned or leased vehicles anticipated to be used by the organization during operation, plans to purchase gases during operation, or land use conversions.
