American ag and ethanol organizations like the U.S. Grains Council, Growth Energy, and the Renewable Fuels Association sent a letter to Treasury Secretary Janet Yellen on sustainable aviation fuel.
When it comes to global actions to decarbonize the aviation transportation sector using Sustainable Aviation Fuel, the industry wants to encourage the use of updated carbon-intensity scoring in the GREET model. They don’t want scoring used in the CORSIA model for corn-based ethanol SAF. The letter says, “We strongly support adopting the DOE’s GREET Model as the standard for carbon intensity scoring of conventional aviation fuels and SAF. The latest GREET model relies on the most current information and highest-resolution data regarding the energy use, carbon emissions, and potential land use impacts associated with the corn ethanol-based SAF process.”
The letter also says GREET allows the Treasury to unlock the full potential of agriculture to meet the growing global aviation industry SAF demand.
