Pledges are due in the first quarter of next year. Mr Davey, who will attend the second week of the talks, told the Telegraph he hoped Lima at least would result in agreement on what information countries must give about their planned emissions reductions so the world could “compare apples with apples”. But he said: “No one is under any illusions that by the time most countries have put forward their initial pledges ... we will be well short of where we need to be.”
