U.S. Clean FuelS Programs

There are three major clean fuel programs in the U.S. used to improve the nation's air quality and reduce oil imports. The most recent is the national renewable fuels standard. The federal reformulated gasoline program is designed to help control ozone pollution and the wintertime oxygenated gasoline program is designed to control carbon monoxide (CO). The RFG program was passed in 1990 and while it no longer requires the use of oxygenates the petroleum industry is utilizing clean burning ethanol in many of its fuel formulations.

Since the establishment of the oxygenated fuels program, EPA statistics revealed sharp declines in harmful carbon monoxide emissions. In areas operating the program for the first time, there was a 95% reduction in the number of days exceeding the CO health standard!

The Reformulated Gasoline (RFG) Program has enjoyed similar successes with all cities utilizing this pollution-fighting fuel experiencing dramatic decreases in the number of days exceeding the ozone standard. RFG with oxygenates performed better and at less cost than had been predicted.
