Can a fleet manager save money and reduce emissions by purchasing an alternative fuel vehicle? The U.S. Department of Energy’s Clean Cities program can help you find out with the newly released Vehicle Cost Calculator.

The online tool compares emissions and lifetime ownership costs of vehicles that run on conventional fuels, alternative fuels and electricity. It puts a massive amount of data at users’ fingertips, giving a picture of the long-term costs and benefits of the thousands of vehicle models now on the road.
