Ratchets, phase-downs and a fragile agreement: how Cop26 played out

Last-minute hitch on coal almost reduced Alok Sharma to tears as Glasgow climate pact made imperfect progress

As weary delegates trudged into the Scottish Event Campus on the banks of the Clyde on Saturday, few realised what a mountain they still had to climb. The Cop26 climate talks were long past their official deadline of 6pm on Friday, but there were strong hopes that the big issues had been settled. A deal was tantalisingly close.

The package" on offer was imperfect - before countries even turned up in Glasgow they were meant to have submitted plans that would cut global carbon output by nearly half by 2030, to limit global heating to 1.5C above pre-industrial levels. Although most countries submitted plans, they were not strong enough and analysis found they would lead to a disastrous 2.4C of heating.
