Which States are participating in CORSIA?
ICAO has decided to use a phased implementation for the CORSIA to accommodate the special circumstances and respective capabilities of States (SCRC), in particular developing States, while minimizing market distortion.
Pilot phase applies from 2021 through 2023 to States that have volunteered to participate in the scheme.
List of States that intend to volunteer in CORSIA from its outset as of 24 May 2017:
First phase applies from 2024 through 2026 to States that voluntarily participate in the pilot phase, as well as any other States that volunteer to participate in this phase.
Second phase applies from 2027 through 2035 to all States that have an individual share of international aviation activities in RTKs in year 2018 above 0.5 per cent of total RTKs or whose cumulative share in the list of States from the highest to the lowest amount of RTKs reaches 90 per cent of total RTKs, except Least Developed Countries (LDCs), Small Island Developing States (SIDS) and Landlocked Developing Countries (LLDCs) unless they volunteer to participate in this phase.
List of States that will have to mandatorily participate in CORSIA in Second Phase not taking into account whether these States participated voluntarily in previous phases(based on last available international aviation activities in RTKs in year 2014):
