ENVIRONMENTAL PROTECTION REQUIREMENTS (See GM1 21L.B.61(c)(1)) Volumes I, II and III of Annex 16 to the Chicago Convention are available at https://elibrary.icao.int/. Since the Standards and Recommended Practices in Annex 16 Volumes I, II and III 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, it is recommended that the declarant may contact the Environment and Sustainability Section of EASA to confirm the environmental protection requirements that are applicable to their particular product and at any stage of the declared process for further guidance.
