Toxic emissions from gas-burning motor vehicles have been reduced over the past 12 years due to federal clean fuel programs and reformulated gasoline, a new federal government report shows.
Changes in gasoline composition to comply with federal clean fuel programs between 1995 and 2005 resulted in emission reductions that were often "substantially greater than regulatory requirements," according to a new analysis issued today by the U.S. Environmental Protection Agency.
The EPA adopted clean fuel programs for gasoline as a result of the Clean Air Act of 1990.
In 1995, the agency implemented the reformulated gasoline program, designed to reduce emissions of smog-forming volatile organic compounds, VOCs, and oxides of nitrogen, NOx, as well as air toxics such as benzene and formaldehyde from motor vehicles.
