Annual CO2 emissions from passenger vehicles

This is a simple simulation that allows you to calculate the annual CO2 (carbon dioxide) emissions of your own gas-powered car, as well as to look at the approximate total annual emissions from all 250 million US passenger vehicles.

Change the sliders to see how driving less and/or driving a vehicle with better mileage changes the amount of CO2 emitted, or to see the impact of the federal government mandating higher-mileage vehicles.

Some of the data comes from this website at the US Environmental Protection Agency. Note that, in 2015, the average gas mileage of a passenger vehicle in the United States was 22.0 miles per gallon, and, on average, each of these vehicles traveled 11443 miles.
