Grassley disappointed in GREET modification delay

U.S. Senator Chuck Grassley is disappointed EPA delayed the release of modeling the agency will use to measure greenhouse gas emissions from jet fuel.

The Iowa Republican tells Brownfield he’s not sure why an announcement on GREET revisions was pushed back.

“I don’t have a reason for the delay, and I don’t know whether (the administration) gave one. But putting this off isn’t helping the grain farmer, and that’s pretty important. it’s bad for farmers (and) it’s bad for investment.”

Under the current GREET model, ethanol derived from corn does not meet the required carbon intensity score for sustainable aviation fuel.

Grassley suggests that industry will struggle without corn ethanol as a primary feedstock.

“You have this situation where I just don’t think there’s going to be enough feedstock if you don’t increase grains, so I think this delay is bad.”

The Biden administration had given itself a March 1st deadline to complete modifications to the GREET model for sustainable aviation fuel.
