URBANDALE, Iowa (Dec. 15, 2023) – The American Carbon Alliance (ACA) released the following statement from ACA CEO Tom Buis, on the U.S. Treasury’s adoption of the U.S. Department of Energy’s Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) model in the evaluation of the life cycle emissions impact of biofuels, specifically within the realm of sustainable aviation fuel (SAF) production:


“Ethanol is the largest sustainable low-carbon fuel that yields advantages beyond conventional energy uses. GREET is the most realistic model in measuring the carbon intensity of biofuels. The American-made GREET model will allow ethanol to serve as the primary feedstock for Sustainable Aviation Fuel, and help the U.S. to become energy independent in the very near future. This change is the right decision and benefits American aviation, boosts energy security, and enhances our path to independence from foreign oil suppliers.”
