Britain is asking countries to push for a global target to cut aviation emissions to levels compatible with the Paris Agreement, under a deal due to be announced at the COP26 climate change summit, according to a draft document seen by Reuters.

As COP26 host, Britain is rallying countries to join an "International Aviation Climate Ambition Coalition" and agree to push the United Nations' aviation agency to set a long-term target to reduce emissions from international flights.

Countries that sign the deal would commit to supporting the adoption by the UN's International Civil Aviation Organization (ICAO) of an "ambitious long-term aspirational goal that is compatible with net-zero global emissions by 2050", the draft said.

The aim is to build momentum for ICAO to set tougher climate targets when its nearly 200 member countries meet in September 2022.
