Airlines face a roughly 150 million-unit shortfall in eligible credits under the Carbon Offsetting and Reduction Scheme for International Aviation ahead of January 2028, the International Air Transport Association said Friday.
Airlines could need more than 200 million eligible emissions units by January 2028 to meet requirements for the 2024-2026 first compliance period, based on IATA traffic forecasts.
As of August, 42 Corsia-compatible letters of authorization covered about 72 million units, leaving the market to add roughly 150 million units over the next 15 months.
Current supply includes units covered by existing authorizations, credits already listed on registries and verified emissions reductions awaiting issuance, with projects across three regions.
Projects in Africa, Latin America and Asia Pacific are supplying the eligible units, with the three regions currently providing similar volumes.
IATA and its supporting alliance are helping host countries authorize verified emissions reductions and removals under Corsia, while advancing Nationally Determined Contributions and sustainable development goals.
