A new study released by the U.S. Department of Agriculture (USDA) finds greenhouse gas emissions from corn-based ethanol are about 39 percent lower than gasoline. The study also states that when ethanol is refined at natural gas-powered refineries, the greenhouse gas emissions are even lower, around 43 percent below gasoline.
“These new findings provide further evidence that biofuels from America’s heartland reduce greenhouse gases even more than we thought, and that our farmers and ethanol plants continue to become more efficient and effective,” said Secretary Sonny Perdue. “President Trump has made it abundantly clear he is unleashing the full potential of American energy production as we retake our rightful place as the world’s leader. Expanding the sale of E15 year-round will provide consumers with more choices when they fill up at the pump, including environmentally friendly fuel with decreased emissions. I appreciate EPA Administrator Andrew Wheeler moving expeditiously to finalize the E-15 rule before the start of summer driving season.”
The study, led by Dr. Jan Lewandrowski of USDA’s Office of the Chief Economist, and published in the journal Biofuels, supports findings of other research that ethanol has a significantly better greenhouse gas profile than previously estimated.
