Page ContentICAO model regulations on CORSIA implementationICAO developed model regulations that aim to facilitate the establishment of a regulatory system for the CORSIA monitoring, reporting and verification (MRV) system by ICAO's Member States, in compliance with the Annex 16, Volume IV. These model regulations are provided for illustrative purposes and do not supersede or replace Annex 16, Volume IV. They are not be prescriptive, mandatory, or construed in any way as to pre-empt individual States' legal structures. The model regulations do not prejudge the form that the legislation takes as such a matter is for each State to decide in light of its domestic legislation. ICAO Member States may use the model regulations as a reference and are free to adapt them to their own specific needs, legislative style and norms to comply with CORSIA requirements. Model Regulations for the Implementation of Annex 16, Volume IV are available as part of training materials at 2019 CORSIA regional workshops here. Spreadsheet for the aggregation of CO2 emissionsIn the context of ACT-CORSIA Buddy Partnerships, a spreadsheet has been developed to assist with the aggregation of CO2 emissions data in preparation of uploading this information on the CORSIA Central Registry. This spreadsheet is meant for use by CORSIA Focal points of ICAO Member States that do not have any other means available to aggregate the CO2 emissions data that they receive from the aeroplane operators attributed to them. The spreadsheet does not supersede or replace the reporting process described in Annex 16, Volume IV. The use of the spreadsheet is voluntary and must not be construed in any way as to pre-empt individual States' use of different software applications or other means for the aggregation of the data from aeroplane operators. Under their responsibility, CORSIA Focal points are free to use and adapt the spreadsheet to their own specific needs to comply with CORSIA reporting requirements.Click here to download the Excel spreadsheet.
