The International Air Transport Association (IATA) has launched the Supporting Alliance for CORSIA EEU Supply initiative to increase the supply of eligible emissions units under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). The goal is to reach between 225 million and 250 million units by spring 2027. The alliance brings together governments, airlines, and experts to address bottlenecks in the carbon credit market and support countries in aligning their Nationally Determined Contributions with CORSIA mechanisms. IATA estimates that CORSIA could generate $4 to $5 billion in climate finance during its first phase and up to $100 billion by 2035, depending on market conditions. The initiative also provides free technical support for countries to authorize national emissions units under CORSIA. More than 32 participants, including major international airlines, have already joined. The first mandatory compliance cycle begins in December 2027.
