U.S. fuel and petrochemical manufacturers have made considerable investments and made tremendous progress in reducing emissions.
EPA data shows that total emissions of the six principal air pollutants in the United States have dropped by 57 percent since 1980 and ozone levels have decreased by 33 percent. These reductions occurred even as industrial output and the number of vehicles on the road have increased. EPA data indicates there will be continued reductions in the years ahead under regulations already in place.
Refiners have cut sulfur levels in gasoline by 90 percent just since 2004. Refiners will make a further significant reduction about 66 percent in 2016. We have also reduced sulfur in diesel fuel by more than 90 percent since 2005 and reduced benzene in conventional gasoline by 45 percent since 2010.
Refiners have spent nearly $50 billion just to remove sulfur from gasoline and diesel fuel and to manufacture reformulated gasoline. AFPM members have additionally addressed requirements for low Reid Vapor Pressure gasoline, including specially blended fuels required by State Implementation Plans under the Clean Air Act, which have reduced hydrocarbon emissions, an ozone precursor.
Between 1990 and 2012 U.S. refiners have invested $137.6 billion toward improving the environmental performance of its products, facilities and operations in technologies to produce even cleaner fuels and meet the growing variety of state and local mandates for fuel formulation.
Refiners' production output increased 14 percent between 1990 and 2013, while their emissions of chemicals monitored under the Toxic Release Inventory decreased 36 percent and the emissions of Hazardous Air Pollutants declined 66 percent.
U.S. fuel manufacturers had invested $20 billion by 2010 to comply with new clean fuel regulations to reduce the sulfur content of gasoline in highway and off-road diesel.
