Clean Fuels Alliance America, the American Soybean Association, the National Oilseed Processors Association, and the U.S. Canola Association this week wrote to a senior energy advisor urging the Biden administration to support the investments made by U.S. companies and farmers who are ramping up production of sustainable aviation fuel (SAF).

The trade associations, whose combined memberships represent the entire value chain for SAF production, sent a letter to John Podesta, Senior Advisor to the President for Clean Energy Innovation and Implementation, asking the administration to recognize the most recent version of the Argonne National Laboratory’s Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model as the “similar methodology” option specified in the Inflation Reduction Act for determining SAF tax credit eligibility.

“U.S. producers of SAF and their partners in farming and oilseed processing should be able to rely on the GREET model to calculate the value of SAF credits. Without this, our combined members and others in the industry may not be able to follow through on investments in SAF production,” the groups state in the letter.

The letter asks the administration to consider the billions of dollars that members of the associations have made to build new or optimize existing production facilities and expand availability of sustainable, homegrown, low-carbon feedstocks like soybean oil and canola. The letter further points out that the SAF Grand Challenge Roadmap recognizes that the goal to produce three billion gallons of SAF by 2030 will rely on expanded use of soybean oil and canola.
