In autumn 2016 ICAO agreed on a global scheme to limit CO2 emissions from international aviation. This measure, called CORSIA, consists of a global offsetting scheme, in which aircraft operators will be required, from 2021, to purchase emissions units, generated by projects in other sectors, to cover any growth in CO2 emissions above 2020 levels. From 2019, aircraft operators will have emissions monitoring and reporting obligations.

Vertis has special expertise on CORSIA and is closely following the ICAO process.

Contact our Head of Aviation Services, Africa Abajas, if you have any doubt about this incoming global scheme.

Learn more about CORSIA

CORSIA will be implemented in phases, starting with voluntary participation (at state level) from 2021 to 2026. Then, from 2027 to 2035 all states will have to participate except those exempted due to very low level of economic development or those with a very small share of international aviation activity. Coverage of the system is established on the basis of routes between states and providing equal treatment to all aircraft operators flying on a given route. Only routes between states that are participating in the Scheme will be covered for offsetting requirements.

74 states have already volunteered to participate in the first phase and from 2019 aircraft operators will have emissions monitoring and reporting obligations.

The material for the implementation of the Monitoring, Reporting and Verification (MRV) system has been developed in the form of ICAO Standards and Recommended Practices that States will have to implement into national measures. Future eligibility criteria for emission units in CORSIA are still under development, and official details are expected in 2018.
