Renewable Fuel Groups along with EPA say a new study on corn waste’s effects on greenhouse gas emissions is flawed. The study published in Nature Climate Change argues biofuels from corn residue may be worse for the climate than gasoline. The Study was done by U-N-L Professor Adam Liska and other researchers not from the Lincoln school. Nebraska Ethanol Board Administrator Todd Sneller says one of the study’s assumption is that corn stover rates calling for over 70 percent removal doesn’t make sense.

Renewable Fuel Association’s Senior Vice President of Research and Analysis Geoff Cooper says the study’s results are based on sweeping generalizations, questionable assumptions, and doesn’t explain why it contradicts other recent and more highly regarded research.

An EPA spokeswoman says the study did not provide useful information relevant to the life cycle greenhouse gas emissions from corn stover ethanol.
