CO₂ emissions from road transportation in the U.S. 2021, by vehicle and fuel type

Published by Ian Tiseo, Apr 26, 2023
In 2021, gasoline-powered passenger cars in the United States released an estimated 360.5 million metric tons of carbon dioxide equivalent (MtCO₂e), compared with 2.7 MtCO₂e released by diesel-powered passenger cars. This significant difference is because gasoline-powered cars are far more common in the U.S. than diesel-powered cars. This is also the case for light-duty vehicles and motorcycles. In comparison, emissions from medium and heavy-duty trucks and buses are predominantly produced by diesel engines.
