Sustainable Alternative Jet Fuels

Commercial aviation faces fuel cost, environmental, and energy security challenges that arise from petroleum-based jet fuel use. Sustainable alternative jet fuels can help to address these challenges. Their use could reduce emissions that impact surface air quality and global climate while expanding domestic energy sources that diversify fuel supplies, contribute to price and supply stability, and generate economic development in rural communities.

FAA is working to enable the U.S. use of one billion gallons per year of "drop-in" sustainable alternative jet fuels by 2018. Though these alternative fuels are created from renewable sources, drop-in fuels mimic the chemistry of petroleum jet fuel and can be used in today's aircraft and engines without modification and provide the same level of performance and safety as today's petroleum-derived jet fuel.

Sustainable alternative jet fuel development and deployment is also a key element of the U.S. Aviation Greenhouse Gas Emissions Reduction Plan (PDF).

FAA provides leadership in this evolving field through activities that support the development and use of sustainable alternative jet fuels. These include:
