THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations (EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC) No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91 [^ntr1-L_202501065EN.000101-E0001], and in particular Article 19(1) and (3) thereof,

Whereas:

• (1) On 28 February 2025 the Commission adopted Delegated Regulation (EU) 2025/870 [^ntr2-L_202501065EN.000101-E0002] updating the references made in Article 9 of Regulation (EU) 2018/1139 to the environmental protection requirements in Annex 16 to the Convention on International Civil Aviation, signed in Chicago on 7 December 1944 (‘Chicago Convention’). Aircraft, other than unmanned aircraft, and their engines, propellers, parts and non-installed equipment are to comply with those environmental protection requirements.

• (2) Existing environmental protection provisions in Commission Regulation (EU) No 748/2012 [^ntr3-L_202501065EN.000101-E0003] should be updated for consistent implementation of the applicable environmental protection requirements.

• (3) Regulation (EU) No 748/2012 should therefore be amended accordingly.

• (4) Commission Delegated Regulation (EU) 2022/1358 [^ntr4-L_202501065EN.000101-E0004] inadvertently omitted the title of Annex Ib to Regulation (EU) No 748/2012. Therefore, the title of Annex Ib should be inserted.

• (5) Commission Delegated Regulations (EU) 2022/1358, (EU) 2023/1028 [^ntr5-L_202501065EN.000101-E0005] and (EU) 2024/1108 [^ntr6-L_202501065EN.000101-E0006] successively amended Article 9 of Regulation (EU) No 748/2012 and inadvertently introduced inconsistent references and redundancies. Therefore, Article 9 of Regulation (EU) No 748/2012 should be corrected.

• (6) Some provisions of this Regulation amend and correct provisions of Regulation (EU) No 748/2012 amended by Delegated Regulation (EU) 2024/1108 which become applicable on 1 May 2025. Therefore, this Regulation should become applicable on the same date.

• (7) The measures provided for in this Regulation are based on Opinion No 02/2024 issued by the European Union Aviation Safety Agency in accordance with Article 76(1) of Regulation (EU) 2018/1139,
