In 2022, gasoline-powered passenger cars in the United States released *** million metric tons of carbon dioxide equivalent (MtCOâ‚‚e), compared with *** MtCOâ‚‚e 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.
