Future GHG Emissions Forecasts <br /> <br />Pleasanton Climate Action Plan Update 45 <br /> <br /> <br />Transportation Emissions <br />Transportation emissions forecasts were developed consistent with the inventory methodology, through <br />the determination of on-road annual VMT multiplied by a year-specific weighted emissions factor for <br />emissions per mile travelled. VMT forecasts for Pleasanton were obtained from the MTC VMT data <br />portal.60 The MTC Traffic Demand Model was used to model VMT through 2050. Emissions factors were <br />established for each year through the use of the EMFAC2017 GHG module, which established VMT and <br />total emissions for each vehicle type in Alameda County. These emissions factors were applied in each <br />year to establish transportation emissions forecasts as shown in Tables 30 and 31. <br />Table 30 Transportation Adjusted Forecast Scenario Methodology <br />Source <br />Category <br />Forecasted <br />Scaling Factor Emissions Factor Applied Legislative Reductions <br />On-road <br />Transportation <br />MTC VMT <br />Modeling1 <br />EMFAC2017 model analyzing light <br />duty (LDA, LDT1, LDT2, MDV, <br />MCY) and heavy duty (LHD, T6, <br />T7, PTO, MH, SBUS, UBUS, OBUS, <br />Motor Coach, All Other Buses) <br />vehicles. <br />EMFAC emission factors account for legislative <br />reductions from Advanced Clean Cars, Pavley <br />Clean Car Standards, Tractor-Trailer <br />Greenhouse Gas Regulation, and adopted fuel <br />efficiency standards for medium- and heavy- <br />duty vehicles. <br />Off-Road <br />Transportation <br />OFFROAD2007 <br />Model2 <br />OFFROAD2007 Model N/A <br />MT CO2e: metric ton of carbon dioxide equivalent; VMT: vehicle miles traveled <br />1 MTC VMT data portal incorporates data from the MTC’s large-scale simulation model of daily travel behavior, used for its regional <br />planning efforts and in Plan Bay Area.
