The FAA is working to build a net-zero sustainable aviation system by 2050 and is committed to making aviation cleaner, quieter, and more sustainable. At the United Nations Climate Change Conference in November 2021, U.S. Transportation Secretary Pete Buttigieg released the U.S. Aviation Climate Action Plan that sets out to achieve net-zero greenhouse gas emissions from the U.S. aviation sector by 2050. Because transportation produces the most emissions, the U.S. DOT and FAA need to be a large part of the solution. This ambitious, but achievable action plan, will create a sustainable aviation system. The U.S. also will work with international partners to maintain and strengthen the Carbon Offsetting and Reduction Scheme for International Aviation.
