Markets & Policy
CORSIA
The international aviation offsetting scheme, which sets eligibility criteria for the credits airlines may use.
CORSIA requires airlines to offset emissions above a baseline on international routes, using credits that meet specific eligibility conditions set by the scheme's governing council.
Its criteria are influential beyond aviation, because they establish a compliance-grade benchmark for what counts as an acceptable credit, including vintage limits and corresponding adjustment requirements in later phases.
Frequently asked questions
Which credits are eligible?
Those from programmes and vintages approved under the scheme's rules, subject to periodic review.
Why does it affect voluntary markets?
Because eligibility signals quality and drives demand, shaping prices across the wider market.
