Q4 CORSIA Credits Procurement Event Now Open

The Q4 CORSIA Credits Procurement Event is open from November 3 to 28, 2025, inviting airlines to purchase carbon credits through the IATA Aviation Carbon Exchange (ACE). This event offers 1 million credits from the Guyana Jurisdictional REDD+ project. In the recent Q3 event, credits sold at a fixed price of $22.55/tonne via the CBL GEO-CP1 spot contract, which acts as the market benchmark for CORSIA Phase 1. Airlines can monitor this benchmark using the Offset Compliance Simulator on IATA EcoHub. More procurement events are planned for 2026 with increasing supply of eligible emission units (EEUs).
