Expands U.S. Department of Agriculture bioenergy programs to include sustainable aviation fuel (SAF) and sets a clear federal definition for what counts as SAF. It directs USDA to lead and coordinate efforts to speed up SAF development, commercialization, and rural economic benefits.

It defines technical and environmental standards for SAF, including at least a 50% lifecycle greenhouse gas reduction compared to conventional jet fuel and limits on eligible feedstocks and processing methods. It also updates an existing USDA assistance program for biorefineries and biobased products so it explicitly supports SAF projects.
