The United Nations’ aviation agency, ICAO, has agreed on certification procedures to support a new carbon dioxide (CO2) emissions standard for aircraft, as well as a new Chapter 14 noise standard for future commercial aircraft that will result in quieter skies and airports.
The new Chapter 14 noise standard is quieter by seven Effective Perceived Noise Decibels, compared to the current Chapter 4 Standard, which took effect from 2006. The Chapter 14 noise standard applies to newly-designed high-weight aircraft entering service from 2017 and for lower weight aircraft entering service from 2020.
The new CO2 and noise standards will be presented for final review and approval by the ICAO Council later this year and will come into force 31 December 2017.
