As of 31 May 2017, 70 States, representing over 87.7% of international aviation activity, expressed their intention to voluntarily participate in the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).
In October 2016, the ICAO adopted CORSIA in an effort to stabilize aviation emissions at 2020 levels.
After 2020, airlines will be required to offset any growth in their emissions by buying credits from projects that reduce emissions, such as forestry or renewable energy projects.
1 June 2017: As of 31 May 2017, 70 States, representing over 87.7% of international aviation activity, expressed their intention to voluntarily participate in the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) – the global market-based measure (MBM) of the International Civil Aviation Organization (ICAO).
In October 2016, the ICAO adopted CORSIA in an effort to stabilize aviation emissions at 2020 levels. After 2020, airlines will be required to offset any growth in their emissions by buying credits from projects that reduce emissions, such as forestry or renewable energy projects.
Participation in both the pilot phase (2021-2023) and first phase (2024-2026) is voluntary. The subsequent phase (2027-2035) would bring all States on board, though exemptions were agreed for least developed countries (LDCs), small island developing States (SIDS), landlocked developing countries (LLDCs) and States with minimal international aviation activity.
CORSIA seeks to complement a broader basket of measures to achieve the global aspirational goal of carbon-neutral growth from 2020 onwards. [ICAO CORSIA Webpage] [SDG Knowledge Hub Story on the Adoption of CORSIA]
