A deal to reduce pollution from commercial flights is expected to be reached at UN talks in Montreal this week.
It would be the first agreement to curb emissions in the industry as aviation has never been part of international talks to cut emissions before, not even in the Paris Agreement.
The draft document from the International Civil Aviation Organisation stated airline emissions will effectively be capped in 2020 and would cost airlines less than 2% of industry revenue.
The deal is said to be backed by the US, China and the Unites Arab Emirates.
Miguel Arias Canete, European Union Climate Action Commissioner told reporters: “The proposal on the table is not as ambitious as we would like but if there are sufficient numbers of countries participating in the beginning, we can work on ambition.”
