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 the 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 travel 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. 

You can determine your current car’s efficiency and compare different models at fueleconomy.gov. And check out the Fuel Economy Guide produced by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE), which can help you choose the most fuel-efficient vehicle that meets your needs.
