APPLICABLE ENVIRONMENTAL PROTECTION REQUIREMENTS The applicable environmental protection requirements are the Standards and Recommended Practices (SARPs) in Volume I ‘Aircraft Noise’, Volume II ‘Aircraft Engine Emissions’ and Volume III ‘Aeroplane CO2 Emissions’ of Annex 16 to the Chicago Convention for products for which the first subparagraph of Article 9(2) of Regulation (EU) 2018/1139 applies. The applicable levels of amendments to Annex 16 to the Chicago Convention are those adopted in the first subparagraph of Article 9(2) of Regulation (EU) 2018/1139. Related guidance material is provided in the attachments to these Annex 16 volumes and in ICAO Doc 9501 ‘Environmental Technical Manual’, Volume I ‘Procedures for the Noise Certification of Aircraft’, Volume II ‘Procedures for the Emissions Certification of Aircraft Engines’ and Volume III ‘Procedures for the CO2 Emissions Certification of Aeroplanes’. However, these SARPs apply only to certain categories of products and as such do not necessarily apply to all products that are within the scope of Subpart C. The applicability of the SARPs is provided in the administration chapters and in the specific applicability sections of the chapters of Annex 16 Volumes I, II and III.
