New study questions climate impacts of biofuels

A study released Feb. 14 by the Proceedings of the National Academy of Sciences claims that ethanol is likely a bigger contributor to global warming than gasoline, ProAgro Group reports, citing World-Grain.

The study contradicts previous findings by the US Department of Agriculture (USDA) showing that ethanol and other biofuels are green.

“Corn ethanol is not a climate-friendly fuel,” said Dr. Tyler Lark, assistant scientist at University of Wisconsin-Madison Center for Sustainability and the Global Environment and lead author of the study.

The research was funded in part by the National Wildlife Federation and the US Department of Energy. It said ethanol is likely at least 24% more carbon intensive than gasoline because of emissions resulting from land use changes to grow corn, as well as processing and combustion, Reuters said.

The Renewable Fuels Association said the study was completely fictional and erroneous noting that the authors used “worst-case assumptions and cherry-picked data.”
