EPA Science Advisory Board questions ethanol’s carbon footprint

Ethanol’s carbon intensity score is being questioned by EPA’s Science Advisory Board. 

In a letter to EPA administrator Michael Regan, Renewable Fuels Association CEO Geoff Cooper blasted the advisory board for making unfounded claims including that there are few if any climate benefits related to substituting corn ethanol for gasoline.

American Coalition for Ethanol CEO Brian Jennings tells Brownfield it sounds like there’s either an axe to grind with production agriculture or a lack of understanding.

“The lifecycle science behind corn farming, grain farming in general, and how agricultural feedstocks can be very sustainably and efficiently converted to biofuel.”

He says studies show corn ethanol is at least 50 percent cleaner than gasoline.

The Science Advisory Board has recommended EPA conduct more extensive research on ethanol’s carbon footprint.

Brownfield interviewed Jennings during the ACE Ethanol Conference in Minneapolis Friday.
