Despite concern over increased air pollution, greenhouse gas emissions, and the potential to harm endangered species, a bipartisan group of Midwest governors and fuel industry leaders are pushing the federal government to approve increased ethanol sales this summer.
Ethanol, a renewable fuel made out of corn, is not normally available in the summer months as it is linked to increased levels of smog. The strain of ethanol known as E15, which means it is at most 15 percent ethanol and 85 percent gasoline, can not be sold in the summertime, specifically from June 1 to September 15.
