WASHINGTON – The U.S. Treasury Department yesterday released long-awaited guidance updating the Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) model for sustainable aviation fuel (SAF) credits under Section 40B of the Inflation Reduction Act. 

NFU President Rob Larew issued the following statement in response to the announcement: 

“Family farmers have the potential to rapidly drive climate solutions with the production of sustainable aviation fuel from homegrown feedstocks. While we appreciate the administration modifying the GREET model and issuing guidance on the 40B tax credit, more work is needed to better recognize and credit certain climate-smart agriculture practices to reduce greenhouse gas emissions in SAF production. 

As the administration works on the next set of guidance for Section 45Z, the Clean Fuels Tax Credit, a wider variety of climate-smart agriculture practices must be included to achieve our nation’s climate goals. It is vital that agricultural feedstocks continue to decarbonize fuels for vehicles and aviation.”
