Do Commercial Airplanes pollute the air?
EPA reports that commercial airplanes and large business jets contribute 10 percent of U.S. transportation emissions, and account for three percent of the nation's total greenhouse gas (GHG) production. Jun 9, 2022

New aircraft from Boeing, Airbus, and other smaller manufacturers already meet the CO2 emission requirements, and by 2020 the average new aircraft was estimated to “outperform” the standard by approximately 10 percent. The EPA issued a Finding in August of 2016 that aircraft GHG emissions “cause or contribute to air pollution that may reasonably be anticipated to endanger public health and welfare.”
This permitted the agency to set CO2 emission standards for U.S. aircraft under the Clean Air Act that match or exceed the ICAO requirements. The industry favored adopting the ICAO specifications, and EPA established the final rule matching ICAO’s carbon emission standards on January 11, 2021.
As airlines bring new equipment into their fleets, their overall fleet performance will improve. By 2028, all regional and seven of 10 mainline U.S. carriers will meet the emission standard for their fleet averages. Two of the remaining carriers, Alaska and Southwest, will be in compliance for their fleet average by 2030.
This will leave only a single airline, Allegiant, with older aircraft needing major improvements to meet the standard. In January 2022, Allegiant announced a plan to purchase 50 new Boeing 737 Max aircraft with deliveries from 2023–2025 and options for an additional 50 737s. This will improve the airline’s overall fleet efficiency.
Given the efficiency of new model aircraft, the ICAO standard is not expected to change current projections of CO2 emissions for the industry, and the standard does not address contrail formation.
