Paragraph 10 of the Assembly Resolution A40-19 defines the coverage of the CORSIA offsetting on the basis of routes between States, with a view to minimizing market distortions between aeroplane operators on the same routes.

For this purpose, the approach is to provide equal treatment of all aeroplane operators on a given route. Specifically:

· A route is covered by the CORSIA offsetting if both States connecting the route participate in the scheme.

· A route is not covered by the CORSIA offsetting if one or both States connecting the route do not participate in the scheme.

It should be noted that the applicability of CORSIA offsetting requirements and the applicability of CORSIA monitoring, reporting and verification (MRV) requirements are not the same. Even if an international flight is not covered by the offsetting requirements, it is still covered by the MRV requirements. The figure below illustrates CORSIA’s route-based approach, and the applicability of MRV and offsetting requirements.
