Control of Air Pollution From Airplanes and Airplane Engines: GHG Emission Standards and Test Procedures (Draft)
Aug. 20, 2020
EPA is proposing GHG emission standards applicable to certain classes of engines used by certain civil subsonic jet airplanes with a maximum takeoff mass greater than 5,700 kilograms and by certain civil larger subsonic propeller-driven airplanes with turboprop engines having a maximum takeoff mass greater than 8,618 kilograms. These proposed standards are equivalent to the airplane CO2 standards adopted by the International Civil Aviation Organization (ICAO) in 2017 and would apply to both new type design airplanes and in-production airplanes. The proposed standards would meet the EPA's obligation under section 231 of the Clean Air Act to adopt GHG standards for certain classes of airplanes as a result of the 2016 "Finding That Greenhouse Gas Emissions From Aircraft Cause or Contribute to Air Pollution That May Reasonably Be Anticipated To Endanger Public Health and Welfare. Accordingly, EPA is proposing to use the fuel-efficiency-based metric established by ICAO. Written comments on this proposal must be received on or before 19 October 2020.
