Technology and Design

  • Recent certification data demonstrates that advanced technologies developed in the 2010-2015 period continue to be integrated into new designs since 2015.
  • The average noise level of the twin-aisle aircraft category has significantly reduced since 2008 due the introduction of the Airbus A350 and Boeing 787.
  • Supersonic aircraft, and other new technologies, need to be carefully integrated into the aviation system to avoid undermining progress in mitigating environmental impacts.
  • Investment in novel technology is drawing on a wider pool of expertise and innovative approaches from other sectors, thereby creating new opportunities to address the environmental impacts from aviation.
  • New aircraft noise standard became applicable on 1 January 2018.
  • New aeroplane CO2 and engine PM standards will become applicable on 1 January 2020.


The growth in the aviation sector since the 1950s has delivered major benefits. However, there have been increasing concerns over the associated environmental impacts. Development of new aircraft technology, and its incorporation within advanced designs that are cleaner and quieter, is one of the key ways to mitigate the environmental impact from aviation.

The EU and EFTA have aircraft and engine environmental certification standards [19] which refer directly to the equivalent International Civil Aviation Organization (ICAO) standards [20], [21], [22]. ICAO’s Committee on Aviation Environmental Protection (CAEP) is responsible for maintaining these standards, and an overview of the noise and emissions certification measurement procedures can be found in Appendix D.

This section of the report contains certified data for aircraft and their engines, which allows to compare the environmental performance of different products. Additional interactive graphs are available on the European Aviation Environmental Report website.
