US proposes new rule that forces new plane designs to be sustainable

The US Department of Transportation’s (DOT) Federal Aviation Administration (FAA) released a proposed rule on 6/16 to reduce greenhouse gases emitted by most large aircraft flying in US airspace. The rule would require more fuel efficiency for new subsonic jet aircraft and large turboprop and propeller aircraft that are not yet certified, and for new aircraft manufactured after January 1, 2028. “It is an important step in reducing the amount of emissions of greenhouse gases released by our country’s planes, and ultimately, achieving President Biden’s ambitious goal of net zero emissions by 2050″, said US Transportation Secretary Pete Buttigieg. Examples of commercial aircraft that will need to meet the proposed standards include the upcoming Boeing 777X and future versions of the 787 Dreamliner and Airbus A330neo; commercial jets like the Cessna Citation; and civil turboprop aircraft such as the ATR 72 and the Viking Limited Q400. The proposed rule does not apply to aircraft already in service. Today’s action is part of the US Aviation Climate Action Plan, which aims to achieve net zero greenhouse gas emissions from the US aviation industry by 2050. Over the past year, the FAA has announced more than USD 100 M in matching research contracts to increase aircraft efficiency, reduce aircraft noise and emissions, and develop and implement new software to reduce taxi delays. These efforts build on the Biden-Harris Administration’s Sustainable Aviation Fuels Challenge, announced last year. The emission standard, in the proposed rule, uses a metric that equates fuel efficiency and consumption with reductions in carbon dioxide (CO2). The proposed rule also accommodates a wide range of fuel-efficient measures in aircraft manufacturing, including improvements in aerodynamics, engine propulsion efficiency, and reductions in an aircraft’s mass before loading. The FAA proposal aligns with the CO2 emission standards for aircraft established by the United Nations’ International Civil Aviation Organization (ICAO) and USEPA regulations implementing the ICAO standard. Thus, it ensures the worldwide acceptance of US-made aircraft and aircraft engines.
