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

• ED Decision 2025/016/R found in: Initial Airworthiness and Environmental Protection (748/2012) (Nov 2025)

##### GM1 21.B.326(a)(3) and (b)(3) Certificate of airworthiness *ED Decision 2025/016/R* **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](#_DxCrossRefBm485231132)(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](#_DxCrossRefBm485231132)(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]](#_ftn44). 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’. --- [[44]](#_ftnref44) <https://www.easa.europa.eu/en/domains/environment/easa-aeroplane-co2-emissions-database-0>
