IATA is pushing back on European Union plans to expand its emissions trading system, arguing the move would create overlapping carbon-pricing regimes and undermine the global CORSIA framework for international aviation. The EU is reviewing its ETS with proposals to cover flights to destinations within 5,000 km of Frankfurt. IATA estimates the expansion could raise airline compliance costs by 40%, to EUR 280 billion between 2027 and 2040. The association wants aviation-related ETS revenues ring fenced for sustainable aviation fuel, infrastructure, and new technology, and it wants the proposed EU ETS as a Service mechanism removed. The warning comes as CORSIA faces a supply crunch. Airlines may need more than 200 million eligible emissions units by January 2028, but only about 72 million were covered by host country Letters of Authorization as of August 2026. IATA's alliance is targeting 225 to 250 million units available by spring 2027.
