The aviation industry currently accounts for 2 percent of global carbon emissions, the vast majority of which is due to the use of fossil jet fuel. As air travel grows at a projected rate of 3 to 4 percent per year, the aviation industry will continue its reliance on energy dense liquid fuels with few transformative mitigation technologies on the horizon. Sustainable aviation fuel (SAF) offers a drop-in replacement for traditional petroleum-based jet-fuel and a path forward to reduce the emissions of air travel in the near-term. Scaling SAF technology and production to meet the needs of the growing aviation industry requires a combination of private and public investment, research and development, infrastructure build-out, and workforce development. The success of these efforts will depend on collaboration among industry, government, academia, and non-governmental organizations.
