(NAFB.com) – The Biden administration released guidance on its sustainable aviation fuel subsidy program that allows corn-based ethanol to qualify for the program if it’s sourced from farms using climate-friendly growing techniques. Farm Policy News from the University of Illinois says SAF can be made from corn, soy, or other agricultural products. To access the subsidies that make it economically viable, refiners must demonstrate their fuel is at least 50 percent lower in emissions than petroleum jet fuel. Ethanol-based SAF can meet that threshold only if corn farmers use a bundle of agricultural practices that include no-till, cover cropping, and efficient fertilizer application that holds carbon in the soil. The announcement also says soy-based biodiesel will qualify if the soy farms use a combination of no-till and cover cropping. SAF producers are eligible for a tax credit of $1.25 to $1.75 per gallon. “This is a stepping stone,” says Ag Secretary Tom Vilsack.
