China, the United States and Europe all pledged support on Saturday for a new deal to curb carbon dioxide emissions by airlines which is due to be finalized at a meeting of the UN's International Civil Aviation Organization (ICAO) in September and is expected to go into effect from 2021.
Aviation was excluded from last December's climate accord in Paris when countries agreed to limit the global average rise in in temperatures to “well below” 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
The proposed new deal on aviation, which aims to cap the carbon pollution of all international flights at 2020 levels will be voluntary between 2021 and 2026 and then mandatory from 2027 for the world’s largest emitters.
Airlines in participating countries would need to limit their emissions or offset them by buying carbon credits from designated environmental projects around the world.
ICAO has estimated that carbon offsetting will cost operators 0.2-0.6 per cent of total revenue from international aviation beginning in 2025, and 0.5-1.4 per cent from 2035.
