ICAO joins IATA alliance to boost CORSIA credit supply

ICAO joined the IATA‑led alliance to expand CORSIA credit supply, a move announced on 13 October during IATA's World Sustainability Symposium in Brussels.

The alliance now includes more than 80 players of the CORSIA ecosystem; as of August 2026 there were 42 CORSIA‑compatible letters of authorization covering 72 million eligible emissions units, representing between 29% and 36% of the estimated demand of 200 to 250 million units for the first compliance cycle (2024‑2026). IATA has set a target of having between 225 and 250 million eligible emissions units available by the northern spring of 2027.
