As Treasury considers how to measure greenhouse gas emissions as it allocates tax credits for sustainable aviation fuels, the National Corn Growers Association’s (NCGA) Corn Congress, meeting in Houston, Texas, reaffirmed their support today for the use of the GREET model in making that determination.
“Corn grower leaders across the country have made it clear that the GREET model is the most reliable measure in determining reductions in greenhouse gas emissions, as it weighs the environmental impacts from the farm to the car or plane,” said NCGA President Harold Wolle. “We strongly encourage the administration to embrace this model, and its accurate and fair calculation of corn’s environmental picture.”
The Inflation Reduction Act, signed into law in 2022, calls for the allocation of $1.25 for each gallon of sustainable aviation fuel in a qualified mixture. To qualify for the credit, biofuels must reduce lifecycle greenhouse gas emissions by at least 50%.
NCGA has aggressively called on the Biden administration in general and Treasury Secretary Janet Yellen in particular to use GREET, formally called Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation, which was developed by the U.S. government and accurately shows the greenhouse gas emissions of corn ethanol.
Agriculture Secretary Tom Vilsack, speaking at Commodity Classic in Houston on Friday, said Treasury will render the decision in the coming weeks.
