Emissions of greenhouse gases from on-road vehicles were estimated using emissions factors from the <br />California Air Resources Board's EMFAC2021 database for the San Joaquin Valley Air District. Baseline year 2024 emission factors were used in this analysis to be conservative. <br />Activity Description <br />Vehicle Type <br />Vehicle <br />Classification <br />Model <br />Year <br />Fuel <br />Type Miles/Trip <br />Annual VMT <br />Attachment A GHG Emission Calculations Page 14 of 25
