The UN International Civil Aviation Organisation ( ICAO ) has put its hopes on a cap and trade system for international flights to cut emissions . It has proposed an offsetting scheme which would run a voluntary second phase from 2021 to 2023 , a voluntary first phase with a fixed cap on offset emissions from 2024 to 2026 , and a mandatory second phase from 2027 to 2035 . The scheme ’s viability will be discussed at the next assembly of the ICAO from 27 September to 7 October . The organisation will decide how emissions will be assigned , either individually ( per airline company ) or sectorally ( per member state ) .
The UN International Civil Aviation Organisation (ICAO) has put its hopes on a cap and trade system for international flights to cut emissions. It has proposed an offsetting scheme which would run a voluntary pilot phase from 2021 to 2023, a voluntary first phase with a fixed agreement on offset emissions from 2024 to 2026, and a mandatory second phase from 2027 to 2035. The scheme’s viability will be discussed at the next assembly of the ICAO from 27 September to 7 October. The organisation will decide how emissions will be assigned, either individually (per airline company) or sectorally (per participating state).
