How Plug-In Vehicles Work

For information on vehicle technologies that can lower greenhouse gas emissions and save on fuel costs, see:


  • SmartWay Transport Partnership is a public/private collaboration between the U.S. EPA and the freight transportation industry that helps freight shippers, carriers, and logistics companies improve fuel-efficiency and save money.
  • SmartWay Light Duty Vehicle Program certifies the cleanest, most efficient cars, trucks, and SUVs each model year, based on their greenhouse gas and smog ratings.
  • Clean Automotive Technology explores EPA's research in advanced technologies for reducing emissions and improving vehicle fuel efficiency.

    Consumer Information:

  • Fuel Economy & Environment Labels provide the public with information on vehicles’ fuel economy, energy use, fuel costs, and environmental impacts-- including information for advanced technology vehicles like electric cars. Starting with model year 2013 vehicles, these redesigned labels can be seen on all new cars and light trucks in dealer showrooms. With the label, you can make comparisons – car by car – to ensure that you have the best information to save on fuel costs and reduce emissions.
  • Fueleconomy.gov, a joint website of the U.S. Department of Energy and the U.S. EPA, is designed to help you make informed choices when purchasing a vehicle, so you can achieve the best fuel economy and emissions reductions possible. The site provides fuel economy estimates, environmental impact ratings, fuel-saving tips, and information on advanced technology vehicles such as electric vehicles.
  • Green Vehicle Guide helps you find information on vehicles that are more efficient and less polluting. Reducing vehicle emissions and increasing your fuel economy helps the environment and your wallet.
