Allowing gas with 15% ethanol content can create more air pollution

See Biden to Allow More Ethanol in Gas This Summer in Bid to Lower Prices: Action could pay off politically in farm states that produce ethanol, but oil companies question the benefits by Timothy Puko of The WSJ. Excerpts:

"the U.S. will allow gas with 15% ethanol content—known as E15—to be sold between June 1 and Sept. 15, when it normally isn’t allowed because it can create more air pollution."  

"The use of ethanol “has resulted in the conversion of millions of acres of marginal croplands and wildlife habitat into corn production” while also increasing fertilizer pollution in waterways and raising pressure on food prices, said David DeGennaro, climate and biofuel specialist at the National Wildlife Federation."

"Expanded ethanol production under the program raised corn prices by 30% and the prices of other crops by 20%, according to a report published earlier this year in Proceedings of the National Academy of Sciences. The report also said growing more corn for ethanol led to increased amounts of water pollutants from U.S. farms and negated ethanol’s climate benefits."
