An interagency team led by the U.S. Department of Energy, USDA and U.S. Department of Transportation’s Federal Aviation Administration today released the Sustainable Aviation Fuel (SAF) Grand Challenge Roadmap Implementation Framework. The Implementation Framework highlights current Federal agency capabilities and programs aligned with the actions called out in the SAF Grand Challenge Roadmap and identifies existing gaps where additional effort, public-private partnerships, and support will be needed to meet the goals set forth in the SAF Grand Challenge. 

"Advancing sustainable fuel technologies is essential to building a thriving bioeconomy that benefits all Americans while also cutting harmful emissions and delivering healthier communities,” said Jeff Marootian, principal deputy assistant secretary for DOE’s Office of Energy Efficiency and Renewable Energy. “This framework highlights the incredible opportunity to unlock exciting new economic opportunities for agricultural and rural communities across the nation and build upon the groundwork laid by the Biden-Harris administration to support a growing sustainable aviation fuel industry.”

“Sustainable aviation fuel use expands economic opportunities for American farmers, business owners and rural communities,” said Chavonda Jacobs-Young, under secretary for research, education and economics and the USDA’s chief scientist. “This effort highlights the power of scientific innovation to drive us toward our national goals and the potent momentum of government organizations working together to accelerate progress towards a sustainable future for aviation fuels.”

Since the establishment of the SAF Grand Challenge in 2021, which set an ambitious goal to produce 3 billion gallons of SAF by 2030, and 35 billion gallons of SAF by 2050 to meet 100% of domestic jet fuel demand, annual SAF production has dramatically increased—highlighting the growing momentum for this important initiative to reduce carbon emissions from the aviation sector. By mid-2024, 13 million gallons of SAF were domestically produced. Announced domestic projects represent potential for over 3 billion gallons of annual SAF production capacity—representing $44 billion of announced investment—by 2030.

The Commercial Aviation Alternative Fuels Initiative estimates that about 2 billion gallons of SAF are currently expected to come online by 2028; additional volume can be expected if barriers are addressed as described in the Implementation Framework, such as market demand, policy framework, and airline offtake agreements. 

The Implementation Framework is a directional guide for the SAF Grand Challenge Roadmap and demonstrates coordination and planning for the multiple agencies involved with different missions and approaches. Organized by six roadmap action areas, the Implementation Framework covers feedstock innovation, conversion technology innovation, building supply chains, policy and valuation analysis, enabling end use, and communicating progress and building support. The SAF Grand Challenge interagency team is committed to supporting achievement of the SAF Grand Challenge goals as demonstrated through: 

• Research and development of sustainable feedstock and fuel production technologies, providing support for technology scale-up and advancing environmental analysis of SAF. 
• Support of U.S. farmers with climate-smart agriculture practices and research. 
• Loan guarantees to commercial-scale SAF projects that utilize innovative technology to convert feedstock to SAF and avoid, reduce, or sequester greenhouse gas emissions. 
• Provision of capabilities and funding to support SAF qualification, U.S. and international standard-setting, and development of infrastructure and transportation systems 

The U.S. transportation sector has become the largest source of carbon dioxide (CO₂) emissions in the country with aviation generating approximately 11% of U.S. transportation-based CO₂ emissions that contribute to climate change. Developing innovative technologies to produce SAF will enable the United States to meet President Biden and Vice President Harris’ climate goals and position it as a global leader in the emerging SAF market.

The Biden-Harris Administration continues to collaborate with a broad range of SAF stakeholders that include airlines, aircraft and engine manufacturers, energy producers, researchers, and international participants to build relationships, share and collect data, identify resources, and direct research, development, and deployment of SAF.

The SAF Grand Challenge, launched in 2021, is a government-wide strategy, led by DOE, the USDA, and DOT. It builds on sectorwide industry commitments to foster innovation and drive change across the entire U.S. aviation emissions and ecosystem. In September 2022, federal agencies published the SAF Grand Challenge Roadmap, outlining a whole-of-government approach with coordinated policies and specific activities that should be undertaken by the government to support achievement of the SAF Grand Challenge goals.   

The SAF Grand Challenge supports the U.S. National Blueprint for Transportation Decarbonization aviation goals to reduce all greenhouse emissions from the transportation sector by 2050. The Blueprint, developed by the Departments of Energy, Transportation, Housing and Urban Development, and the Environmental Protection Agency, is a landmark strategy to realize an improved and sustainable transportation future.
