Colorado Springs, Colorado has been picked as the top municipal biodiesel fleet in the nation, according to Government Fleet Magazine.

The Colorado Springs Gazette says the city beat out San Francisco and Austin, Texas for the honor:

The magazine also awarded the city 17th in its overall rankings of public sector fleets using alternative fuels.

Since 2003, more than 2,400 pieces of city equipment have run on biodiesel, consuming almost 1.6 million gallons of B20 biodiesel. That is the equivalent of more than 5 million pounds of carbon dioxide not making it into the atmosphere, or 491 passenger cars not driving for one year.
