Diplomats endorsed the outlines of the proposed deal in Bonn on Friday after five days of fraught negotiation that highlighted just how much work remains to be done in Paris.

The aim is to unite all the world’s nations in a single agreement on tackling climate change, with the goal of capping warming at 2C over pre-Industrial Revolution levels.
For the opening day on 30 November, “we have already received 80 confirmations, including from the presidents of the United States and China, and the Indian prime minister,” French foreign minister, Laurent Fabius, told journalists in Paris on Tuesday.

The leaders of Germany, South Africa, Brazil and Canada have also accepted, he said.

The last attempt at sealing a global climate pact, in 2009, saw about 110 world leaders descend on a UN summit in Copenhagen for the two final days, only to leave frustrated when the negotiations collapsed.

“Together with president Francois Hollande, we decided to invite heads of state to attend the first day and not the end as in Copenhagen,” said Fabius.
