Another salvo has been fired in the academic fight over the Renewable Fuel Standard’s impact on greenhouse gas emissions.
A group of scientists and economists is challenging a highly publicized study published earlier this year that claims corn ethanol is likely more carbon intense than gasoline because of land-use changes driven by the RFS. “Our detailed review of the original paper and the responses by those authors reveals various major deficiencies, problematic assessments, and misinterpretation of the existing literature,” according to the latest comments, posted online by the Argonne National Laboratory. The Renewable Fuels Association has opposed appointment of the lead author of the paper in question, Tyler Lark, a scientist at the University of Wisconsin-Madison’s Center for Sustainability and the Global Environment, to a panel reviewing EPA’s triennial report on the environmental impact of the RFS.
