EPA Collaboration on International Air Pollution Standards for Aircraft
On this page:
The EPA has long collaborated at International Civil Aviation Organization (ICAO) to develop global standards to control emissions from aircraft engines and airplanes. ICAO is a specialized agency of the United Nations (UN)that sets international standards for aviation safety, security, efficiency, capacity, and environmental protection. The EPA works with ICAO’s Committee on Aviation Environmental Protection (CAEP) which was established in 1983 with the purpose to develop global policies and standards related to aircraft noise and emissions. The FAA leads the US delegation to CAEP, and the EPA serves as a technical advisor on the US delegation.
CAEP operates on a 3-year decision making cycle. As of December 2021, CAEP consists of 31 voting member States, 6 observer states, and 15 observer organizations. At the final meeting, of a CAEP cycle, the work program for the next cycle is agreed upon (e.g., at the 12th meeting of CAEP (CAEP/12) in February 2022 the work program for the CAEP/13 cycle, from February 2022 - February 2025, is discussed and agreed). Member States of CAEP meet annually at Steering Group meetings to help direct the technical work during the cycle.
The standards development and analysis work is conducted through technical working groups consisting of representatives from member State regulators, industry, airports, environmental NGOs, and research organizations. Within the working groups at CAEP, the EPA and FAA both serve in leadership roles and provide technical support for testing and standards development.
At the CAEP/12 meeting in February 2022, the US will advocate for beginning work on developing new GHG standards for airplanes, starting work on new NOx and PM standards for aircraft engines, and for additional transparency in the CAEP process. Also, the US will provide its views on ICAO’s long-term aspirational goals and Carbon Offsetting and Reduction Scheme for International Aviation. The US committed to begin releasing its papers to Steering Group and CAEP meetings going forward. These US papers will also be hosted by the US Mission to ICAO, and the US papers relevant to EPA’s work will also be posted here.
