The Alliance of Automobile Manufacturers, Association of Global Automakers, the oil industry and other groups petitioned the court to overturn a ruling in the District of Columbia's Circuit Court of Appeals that none of the groups had legal standing to challenge EPA's approval of E15.
The justices' ruling means that E15 can be sold at gas stations nationwide. Currently the E15 blend is sold in about 20 stations. The American Petroleum Institute has argued that raising ethanol blends could damage automobiles and could raise fuel prices.
Auto makers aren't the only trade groups fighting for the repeal of the Renewable Fuel Standard. Livestock and poultry groups submitted comments Congressional members about the negative impact the RFS has had on their industries. The food industry also has supported legislation that would overturn waivers allowing E15 to be used for many passenger cars and light trucks.
