This October 2022 FAA presentation by Chief Scientific and Technical Advisor Dr. Jim Hileman outlines the agency's efforts to advance Sustainable Aviation Fuels (SAF) as a key strategy for reducing aviation's carbon footprint. SAF are 'drop-in' fuels compatible with existing aircraft and infrastructure, capable of significantly cutting greenhouse gas emissions across their full lifecycle—from feedstock production to combustion. The FAA supports multiple approved SAF production pathways and works with federal partners and international bodies to scale up SAF use as part of broader aviation decarbonization goals.Open full document
