IETA has joined the Supporting Alliance for CORSIA Eligible Emissions Unit Supply, an initiative led by IATA, to increase the availability of high-integrity carbon credits for the Carbon Offsetting and Reduction Scheme for International Aviation. The Alliance, now comprising 50 entities including five governments, aims to address the projected 200 million tonne compliance obligation for CORSIA's Phase 1, which concludes in 2028. As of May 2026, only 36 million tonnes of eligible supply are available, highlighting a significant market shortfall. IETA will provide technical support to scale the market and strengthen supply, particularly by facilitating host country authorisations for CORSIA units. This collaboration seeks to resolve legal and regulatory uncertainties currently hindering both supply and demand in the CORSIA market.
