On June 15, 2022, the Federal Aviation Administration published a notice of proposed rulemaking for creating fuel efficiency requirements for certification of certain airplanes. The rulemaking is intended to ensure compliance with EPA’s airplane emission standards for greenhouse gas emissions under the Clean Air Act. FAA states that because the EPA standard applies to airplanes certificated in the United States even in the absence of the FAA rule, the FAA proposal does not have any incremental benefits, but that it will result in cost savings by enabling U.S. manufacturers to certificate to the EPA standard rather than a foreign authority.
FAA is accepting comments on the proposed rule until August 15, 2022.
