The Biden administration will finalize revisions to its climate model for sustainable aviation fuel (SAF) feedstocks in the coming weeks, a White House official said. “The administration is committed to getting this right – to both reflect the latest science and create new economic opportunities through SAF production – and plan to finalize updates in the coming weeks,” an official told Reuters.
Reuters reporter Jarrett Renshaw tweeted, “Ethanol is not expected to automatically qualify as a feedstock for SAF under the revised GREET model under consideration... forcing producers to cobble together practices like solar power and sustainable farming techniques to push them above the threshold, sources tell me. To qualify for SAF credit, feedstock must be 50% better than petro jet fuel. The model will likely assign a default value for ethanol less than 50%, forcing producers to rely on other items to climb above 50% threshold. Think standard deduction vs itemized deductions. One of the remaining dividing lines among administration officials is how to verify farms are utilizing smart climate agricultural techniques, multiple sources tell me.”
