GM1 21.B.326(a)(3) and (b)(3) Certificate of airworthiness

CO₂ EMISSIONS PRODUCTION CUT-OFF REQUIREMENTS

Volume III of Annex 16 to the Chicago Convention (‘ICAO Annex 16') includes CO₂ emissions production cut-off standards that apply to subsonic jet aeroplanes with a Maximum Take-Off Mass (MTOM) greater than 5 700 kg and propeller-driven aeroplanes with a MTOM greater than 8 618 kg, for which a type certificate was issued but that were not certified for CO₂ emissions in accordance with Volume III of ICAO Annex 16, and for which the individual certificate of airworthiness (CofA) was first issued on or after 1 January 2028 (Sections 2.1.1.(f) and (g) of Chapter 2 of Part II of Volume III of ICAO Annex 16). These production cut-off standards were introduced with the first edition of Volume III of ICAO Annex 16.

— For a new aeroplane (21.B.326(a)(3)):

The competent authority assesses whether an aeroplane CO₂ emissions production cut-off requirement applies to the aeroplane, and, if such a requirement applies, that the aeroplane conforms to this requirement before issuing the first CofA.

— For a used aeroplane that does not have an airworthiness certificate issued in accordance with Part 21 (for example an aeroplane imported from a third country) (21.B.326(b)(3)):

The competent authority assesses whether an aeroplane CO₂ emissions production cut-off requirement applied to the aeroplane when its first CofA was issued, and, if such a requirement applied, that the aeroplane conformed to that requirement on the date on which the CofA was first issued. The competent authority may check that the CO₂ metric value provided by the applicant for a CofA corresponds to the CO₂ metric value approved by the Agency for the aeroplane type.

Note: For a used aeroplane that has an airworthiness certificate issued in accordance with Part 21 (for example an aeroplane imported from a Member State), the compliance with the applicable environmental protection requirements was already assessed for the issuance of the previous CofA.

The competent authority may refer to the corresponding certified CO₂ emissions evaluation metric values that are published by the Agency in the EASA Aeroplane CO₂ Emissions Database[44].

These specific requirements ensure that the CO₂ emissions production cut-off requirement that may apply to the aeroplane is not overlooked. Further guidance material on the applicability of the aeroplane CO₂ emissions requirements is provided in ICAO Doc 9501 ‘Environmental Technical Manual’, Volume III ‘Procedures for the CO₂ Emissions Certification of Aeroplanes’.
