EPA Proposes Emission Standards for Aircraft

The Environmental Protection Agency (EPA) has proposed the first U.S. emission standards for commercial aircraft that align with the U.N. International Civil Aviation Organization’s global emission standards of 2016.  These standards are directed at manufacturers of both small and large aircraft to include Boeing and Airbus SE, which back the measures.

The EPA-proposed regulation seeks to align the United States with the ICAO standards, EPA Administrator Andrew Wheeler said. “We are implementing the ICAO recommendations, ICAO standards.”

The standards would apply to new type designs as of January 2020 and to in-production airplanes or those with amended type certificates starting in 2028. They would not apply to airplanes in use.

Aircraft are believed to account for 12 percent of all U.S. transportation greenhouse gas emissions and 3 percent of total such U.S. emissions. This represents the largest source of transportation-related greenhouse gas emissions not subject to standards.

Wheeler said it was critical the U.S. adopt the standards, because countries could ban U.S.-assembled airplanes if they do not meet ICAO standards.
