NASA is committed to supporting the U.S. climate goal of achieving net-zero greenhouse gas emissions from the aviation sector by 2050. Under the Sustainable Flight National Partnership, NASA is leading federal agencies and industry to accelerate the development of sustainable technologies. This includes enabling use of high-blend sustainable aviation fuels and deploying operational improvements to maximize the efficiency of the next generation single-aisle aircraft. NASA also is looking beyond at what technologies will be needed for the long-term sustainability of aviation.
