EU leaders meet to try to agree on carbon neutrality by 2050

Greenpeace activists unfurl climate emergency banner on Brussels venue before event

European leaders meeting at a summit in Brussels will make a new attempt to set the European Union on course for carbon neutrality by 2050, in a test of the bloc's credibility on the climate emergency.

Hours before EU leaders were due to arrive on Thursday, Greenpeace activists unfurled a banner on the side of the summit venue warning of the climate emergency.
