US ethanol organisations call for the use of GREET model for greater accuracy
US ethanol organisations including the US Grains Council (USGC), Growth Energy and the Renewable Fuels Association (RFA) sent a letter to Treasury Secretary Janet Yellen urging her to use the GREET model for scientific accuracy.
In acknowledging global actions to decarbonise the aviation transportation sector using sustainable aviation fuel (SAF) they urged Yelland to use this model instead of carbon intensity scoring used in the CORSIA model for corn-based ethanol SAF.
The US Grains Council, Growth Energy and the Renewable Fuels Association said in their joint letter: “We strongly support the adoption of the DOE’s GREET model by the US Treasury as the standard for carbon intensity scoring of conventional aviation fuels and SAF.
“The latest DoE 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.
“By incorporating the DOE GREET model into its evaluation framework, the Treasury can unlock the full potential of agriculture to meet the growing demands of the global aviation industry while simultaneously reducing its carbon footprint.”
