A new study published by researchers from Environmental Health and Engineering Inc., Harvard University and Tufts University shows corn ethanol emits 46 percent fewer greenhouse gas (GHG) emissions than gasoline.
According to EH&E, conventional wisdom based on a prior analysis completed by the U.S. EPA estimated that corn ethanol achieved only a 20 percent GHG reduction. EH&E’s topical review of the latest science, however, shows that corn ethanol is less carbon intensive and more climate-favorable than previously thought.
