The U.S. Treasury Department says it will use a modified version of the GREET model as a measurement to determine reductions in greenhouse gas emissions, and that was greeted by ethanol advocates with rejoicing.

The National Corn Growers Association was among those pleased to hear the Treasury’s decision. “Given that GREET was created by the government and is widely respected for its ability to measure reductions in greenhouse gas emissions from the farm to the plane, we’re encouraged by this,” said NCGA President Harold Wolle. “We’re eager to help the aviation industry reduce its carbon footprint and look forward to helping ensure the final model helps achieve that goal.”

GREET, which stands for the Greenhouse Gasses, Regulated Emissions, and Energy Use in Transportation, was developed by the U.S. Department of Energy to measure greenhouse emissions from the field to the car or plane.

The agency will use the model as it allocates tax credits for sustainable aviation fuels under the Inflation Reduction Act.
