EPA developed the Green Vehicle Guide to help you find information on vehicles that are more efficient and less polluting.
Vehicles that operate primarily on gasoline or diesel have historically accounted for over 99% of cars and passenger truck sales. However, sales of cars that operate on other fuels — particularly electricity — are growing. New models of both electric vehicles and plug-in hybrid electric vehicles are entering the market in increasing numbers each year. Other alternative fuel vehicles include those that run on compressed natural gas (CNG) or E85 (a mixture of about 85% ethanol and 15% gasoline).
Many alternative fuels “burn” cleaner than gasoline or diesel so there are fewer tailpipe emissions. The amount of greenhouse gases (GHG) emitted when the fuel is produced depends on the source of the fuel — see GHG Emissions for more information. These fuels can also be produced domestically, reducing our dependence on imported petroleum. In addition, reducing vehicle emissions and increasing your fuel economy helps the environment and your wallet.
