The City of Dallas is doing their part to preserve the environment and reduce petroleum consumption by switching to alternative fuels ever since the start of its compressed natural gas (CNG) program in 1992. The public alternative fuels infrastructure has encouraged other fleets to
use natural gas as well as push for cleaner ways
to solve air pollution problems. The City of Dallas
currently has approximately 937 natural gas fueled
vehicles,131 hybrids, and 11 electric vehicles in
its fleet. In addition to its approach to expand clean and renewable energy, the City of Dallas also runs some of their fleet on biodiesel. The City of Dallas was the first fleet in the nation to utilize the B20 additive, a blend of 20 percent biodiesel and 80 percent petroleum diesel. The B20 helps reduce NOX (oxides of nitrogen) emissions, one of the main causes of ozone pollution problems in North Texas. Currently, over 1,300 city vehicles use B20. The City of Dallas is also a previous winner of the National Partner Award by the U.S. Department of Energy.
