Today’s Solutions: December 16, 2025

Aviation was controversially left out of the final Paris Agreement, but now it seems a much-needed deal to tackle global aviation emissions is set to be delivered this coming September. The deal, led by the U.N-backed International Civil Aviation Organization, would set the first limits on flight emissions and could potentially usher in a global carbon market for the aviation industry. Such a system would require airlines to effectively purchase emission allowances under a capped market that incorporates developing economies to bring finance to projects that can curb emissions cost effectively. The deal would also lead to more efficient planes and could place a cap on emissions from flights at 2020 levels, a proposal already supported by the airline industry. It’s no done deal, but with a growing band of businesses, NGOs and governments putting pressure on the ICAO to create an effective aviation emissions deal, it seems for the first time in years that reaching an agreement looks possible.
