ICAO joins CORSIA Supporting Alliance as eligible carbon credit supply reaches 72 million units

ICAO has joined IATA's CORSIA Supporting Alliance, a group of more than 80 aviation and carbon market stakeholders working to expand the supply of eligible emissions units ahead of the first compliance deadline in 2027. The alliance focuses on removing regulatory and operational barriers around host country authorizations, including accounting arrangements under Article 6.2 of the Paris Agreement. As of August 2026, IATA reports 42 letters of authorization covering roughly 72 million eligible emissions units. That is up from 40 million at the start of the year, but still far below the 200 to 250 million units IATA estimates airlines will need for the first CORSIA compliance cycle. With the first mandatory cancellation deadline set for the end of 2027, the gap between authorized supply and expected demand remains the core challenge.

Good to see ICAO formally inside this alliance. The 72 million units sounds like progress until you put it next to the 200 to 250 million IATA says airlines need for the first cycle. The real bottleneck is host country authorizations under Article 6.2, not registry issuance. More institutional cooperation helps, but the gap is still huge.

So CORSIA's first compliance deadline is end of 2027 and supply is roughly a third of what's needed. That is the kind of number that matters. Also worth noting these units come from projects in Africa, Latin America, Asia-Pacific, which means host country NDCs and corresponding adjustments will decide whether they actually count.

Aviation offsets always make me check the underlying project types. The article says eligible units come from reduction and removal projects, but doesn't break down how much is removals versus avoided emissions. For a scheme meant to reach carbon neutral growth, the mix matters. If most supply is reductions, the durability question stays open.

The interesting part is ICAO joining a body that exists to fix authorisation bottlenecks. CORSIA was always going to live or die on Article 6.2 accounting. Without clear corresponding adjustments, host countries have no reason to approve units and buyers have no way to prove they aren't double counted. The 2027 deadline makes this urgent.

IATA says 42 letters of authorization cover around 72 million units as of August 2026, up from 40 million at the start of the year. That's real growth, but the central demand estimate is 200 to 250 million. So the story here is not just ICAO joining, it's the scale of the shortfall before the first cancellation deadline.

Another signal that carbon credit supply is becoming a policy bottleneck, not just a market one. The alliance focus on technical assistance for authorisations is the right lever. Whether it moves fast enough for 2027 is the question. Also, I would like to see which registries and project standards are supplying those 72 million units.
