RFA calls on the Treasury to use GREET model for SAF tax credit implementation

In Washington, use of science-based, consistent and transparent lifecycle analysis methods will be crucially important in implementing the sustainable aviation fuel (SAF) tax credit under the Inflation Reduction Act, the Renewable Fuels Association said in comments submitted last Friday to the Department of Treasury. RFA’s comments were in response to a request for comments from the Treasury on considerations for implementation of the SAF credit.

RFA continues to believe the most appropriate lifecycle analysis methodology for the determination of SAF emissions is the GREET model, developed and updated regularly by the Department of Energy’s Argonne National Laboratory. Cooper stressed that GREET—an acronym for Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation—is widely considered to be the leading and most sophisticated model, and it is more robust and current than the methodology used by the International Civil Aviation Organization.
