ICAO joins IATA alliance to expand CORSIA’s credit offering

ICAO joined the IATA‑led alliance, a move announced on 13 October at the IATA World Sustainability Symposium in Brussels, after IATA launched the alliance in June at its annual general assembly in Rio de Janeiro with just over 32 members and now more than 80 CORSIA ecosystem actors.

The alliance aims to provide practical assistance to countries for authorising the use of emission units without double accounting; by August 2026 it had issued 42 CORSIA‑compatible authorisation letters covering 72 million eligible emission units, while demand for the 2024‑2026 compliance cycle is estimated at 200‑250 million units and IATA targets 225‑250 million units to be available by the northern spring of 2027.
