Total U.S. CO2 Emissions 5.19% of Total U.S. Emissions are from driving To/From Work * EPA data shows that CO2 emissions from Passenger Cars and Light-Duty Trucks = 1,149 Tg CO2e, or 19.2% of total U.S. CO2 emissions. * Since work-related driving is about 27% of VMT * We can calculate that work trips account for 310.2 Tg CO2e (27% * 1,149). This equates to 5.2% of U.S. emissions. Chart shows total U.S. CO2 emissions from all uses (5,983.1 Tg), 2008 EPA Publication 06.04.08 IAC Transportation Marcus Bowman
