The Environmental Protection Agency released a rulemaking on Monday to lower the amount of sulfur in gasoline and reduce air pollution from automobile emissions.
EPA projects that the rule will slash atmospheric concentrations of smog and soot by requiring refiners to cut sulfur concentrations by more than 60 percent in gasoline blends. The standards also set limits on tailpipe emissions from automobiles.
"I'm proud to announce that today EPA is setting cleaner air pollution standards for cars and for gasoline," EPA administrator Gina McCarthy said during a press call. "These standards will reduce pollution. they'll clean the air we breath and protect the health of american families in a way that respects economic growth."
Automakers and oil refiners will need to invest in new technology by 2017 to comply with the regulation. The rule requires cars to be built with cleaner-burning engines and refiners to use special equipment to strip sulfur from gasoline.
EPA and the oil industry say this will increase the cost of gas and drive up market prices for new cars. There is disagreement, however, over how much prices will rise.
McCarthy said the regulation would "cost less than a penny per gallon of gasoline on average." In contrast, oil industry stakeholders say the standards could tack on an additional 9 cents per gallon of gas.
