Yep, you read that right. A recent study, published in the Proceedings of the National Academy of Sciences, “contradicts previous research commissioned by the U.S. Department of Agriculture (USDA) showing ethanol and other biofuels to be relatively green.”
Under the U.S. Renewable Fuel Standard (RFS), a law enacted in 2005, “the nation’s oil refiners are required to mix some 15 billion gallons of corn-based ethanol into the nation’s gasoline annually.”
This new report shows that “Corn ethanol is not a climate-friendly fuel” and that ethanol “is likely at least 24% more carbon-intensive than gasoline due to emissions resulting from land use changes to grow corn, along with processing and combustion.”
