The Carbon Offset & Reduction Scheme for International Aviation (CORSIA) is a global initiative designed to address greenhouse gas emissions from international aviation.
Administered by the UN’s International Civil Aviation Organization (ICAO), CORSIA mandates that airlines meeting specific criteria must monitor and report their emissions. Emissions are assessed against a 2019 baseline, and any increase above the baseline must be offset with carbon credits, with the goal of achieving carbon neutral growth.
CORSIA has three main Phases:
Pilot Phase (2021-2023):
- Participation is optional for countries.
- Test phase to prepare for future requirements.
Voluntary First Phase (2024-2026):
- Participation is optional for countries.
- 126 countries have committed, affecting flights between participating states.
Mandatory Second Phase (2027-2035):
- Participation becomes compulsory for all international flights.
Airlines have three tools available to deliver carbon neutral growth:
- Improve fleet efficiency
- Increase the use of sustainable aviation fuels (SAFs)
- Purchase carbon credits approved in ICAO’s Eligible Emissions Units document.
Gold Standard has been approved to supply Eligible Emissions Units for the Pilot Phase and Phase 1.
