Who’s who at Cop29? The world leaders and others who will attend

Crucial question for summit will be how to help developing countries cope with extreme weather caused by high temperatures

Cop29 officially opens on Monday 11 November in Baku, Azerbaijan, and the conference is scheduled to end on 22 November, although it is likely to run later. World leaders - about 100 have said they will turn up - are expected in the first three days, and after that the crunch negotiations will be carried on by their representatives, mostly environment ministers or other high-ranking officials.

The crucial question for the summit is climate finance. Developing countries want assurances that trillions will flow to them in the next decade to help them cut greenhouse gas emissions in line with the rapidly receding hope of limiting global heating to 1.5C above preindustrial levels, and to enable them to cope with the increasingly evident extreme weather that rising temperatures are driving.
