Reducing Carbon Emissions through U.S. Sustainable Aviation Fuels

The U.S. transportation sector, including cars, trucks, airplanes, ships, and trains, accounts for 34% of the nation’s greenhouse gas (GHG) emissions and is a significant driver of climate change. While the commercial aviation industry is an important contributor to the U.S. economy, it is also a considerable source (approximately 2%) of domestic GHG emissions.

In an article published in Open Access Government, Dr. Reyhaneh Shenassa, Chief Engineer at the U.S. Department of Energy (DOE) Bioenergy Technologies Office (BETO), explains how U.S. sustainable aviation fuels (SAF) will reduce aviation carbon emissions, and details what DOE is achieving to support the Biden-Harris administration goals to deliver an equitable, clean energy future and economy-wide net-zero emissions by 2050.

To assist in the decarbonization of the aviation industry, the U.S. government has launched several government-wide initiatives, such as the Sustainable Aviation Fuel (SAF) Grand Challenge to generate at least 3 billion gallons of SAF by 2030, and 35 billion gallons by 2050 – enough to meet 100% of annual U.S. aviation fuel demand. The SAF Grand Challenge Roadmap provides an outline of actions by U.S. government agencies to support stakeholders in realizing the challenge goals. Other initiatives include the Clean Fuels & Products Shot™, part of the DOE Energy EarthshotsTM initiative, which supports the development of sustainable feedstocks and conversion technologies to produce crucial fuels and carbon-based products in hard-to-decarbonize sectors, and funding SAF research and development (R&D) through funding opportunities.

Read the Open Access Government article to learn more about how BETO is leveraging national laboratory R&D expertise to help build a successful SAF bioeconomy.

 BETO supports technology research, development, and demonstration to accelerate greenhouse gas emissions reductions through the cost-effective and sustainable use of biomass and waste feedstocks across the U.S. economy. BETO is part of DOE's Office of Energy Efficiency & Renewable Energy.
