Environmental Technical Manual - Volume IV

The second edition of the Environmental Technical Manual (Doc 9501), Volume IV — Procedures for demonstrating compliance with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) includes material that was approved by the ICAO Committee on Aviation Environmental Protection (CAEP) at its eleventh meeting (CAEP/11) in February 2019. This manual is to be periodically revised under the supervision of the CAEP Steering Group and is intended to make the most recent information available to administrating authorities, aeroplane operators, verification bodies and other interested parties in a timely manner, aiming at achieving the highest degree of harmonisation possible.
