The U.S. Environmental Protection Agency (EPA) is proposing to find under the Clean Air Act that greenhouse gas (GHG) emissions from commercial aircraft contribute to the pollution that causes climate change, endangering the health and welfare of Americans.
At the same time, the agency is releasing information about the international process already underway by the International Civil Aviation Organization (ICAO) for developing carbon dioxide (CO2) standards for aircraft and the EPA’s participation in that process. The EPA is now seeking public input to inform future steps by the agency.
For the past five years, ICAO — a specialized body of the United Nations with 191 member states — has been working with the aviation industry and other stakeholders to develop coordinated, international CO2 emissions standards for aircraft. The EPA and the Federal Aviation Administration, representing the United States, are participating in ICAO’s process to ensure that any standards achieve meaningful CO2 emissions reductions through policies that are equitable across national boundaries.
