Compare the Efficiency of Your Car

Daily transportation and business activities contribute a significant portion to greenhouse gas emissions, energy consumption, fossil fuel reliance, and air pollution. Understanding the fuel consumption and efficiency of your car is an important first action step.

 Also known as “fuel economy,” fuel efficiency is a measure of how far a vehicle can travel per unit of fuel. In the United States, this is expressed as “miles per gallon” (mpg). Fuel efficient vehicles require less gas to go a given distance. When we burn less gas, we cut global warming emissions and produce less pollution, while spending less on gas. Improving the fuel efficiency of U.S. vehicles is a large step we can take to cut the country’s oil consumption. 

The U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) produced the Fuel Economy Guide to help car buyers choose the most fuel-efficient vehicle that meets their needs.
