US EPA WILL IMPLEMENT CO2 STANDARDS FOR AIRCRAFT ENGINES
June 13, 2019
The U.S. Environmental Protection Agency (EPA) announced this month that it will issue regulations to implement International Civil Aviation Organization (ICAO) design certification standards for CO2 emissions from aircraft engines. The EPA rules are slated to be published in September 2019 and will be at least as stringent as the standards that ICAO set forth in 2017 as Annex 16 (Environmental Protection), Volume III of the Chicago Convention. ICAO’s standards will apply to new aircraft type designs starting in 2020, and to designs already in production in 2023.
While the Trump Administration is generally skeptical of climate and environmental regulation, the U.S. has continued to move forward with climate commitments under the Chicago Convention. This trend is also illustrated, separately, by the U.S.’s continuing participation in ICAO’s Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), which is articulated by Chicago Convention Annex 16, Volume IV. The EPA’s engine emissions rulemaking had been suspended, but U.S. aircraft engine manufacturers pressed the agency to issue regulations since they participate in a global market and require certainty about future obligations.
