Climate change is a global problem, which requires global efforts. The CORSIA is a global scheme for the global international aviation industry. The more States join the CORSIA, the more emissions are covered by the offsetting requirements of the Scheme and the higher its environmental effectiveness becomes. Each participating State brings ICAO closer to meeting its global aspirational goal of carbon neutral growth. For a State that does not have an operator attributed to it (and therefore no compliance cost is incurred), its participation in the Scheme will add those routes operated by foreign operators between the State and other participating States, thus increasing the overall emissions coverage of CORSIA. For States with particular interest in eco-tourism, participation in CORSIA provides the additional benefit of greening air transport connections to the rest of the world.
States that voluntarily participate in the pilot phase of CORSIA and require assistance will be given priority within the ACT-CORSIA capacity building and assistance programme, with a view to enabling the smooth implementation of the Scheme under the spirit of the "No Country Left Behind". Building upon the experience in previous capacity building and assistance initiatives, this can create further synergies for the improvement of the overall environmental performance in those States.
Assembly Resolution A41-22, paragraph 23, requests the Council to promote the use of emissions units that benefit developing States. Participating in CORSIA will increase the demand for the emissions units to be purchased by aeroplane operators, thus increasing incentives to invest in emissions reduction projects in participating States.
