The 42nd International Civil Aviation Organization (ICAO) General Assembly closed on October 3, 2025, in Montreal.
During these triennial assemblies, delegations from up to 193 states convene to review and set ICAO priorities, budget and goals. This year’s Assembly has been particularly closely watched as it was the first meeting after the previous Assembly’s landmark commitment for international aviation to achieve net zero by 2050.
During the preceding General Assembly in 2022, ICAO had agreed on a Long-Term Aspirational Goal (LTAG) to achieve net-zero carbon emissions by 2050. It also consolidated the implementation of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) as the first global sectoral market-based scheme for international aviation, which has seen the pool of voluntary states’ participation increase from 88 in 2021 to 130 today.
