 Greenpeace says a surprise climate deal between China and the United States, the world's two biggest greenhouse gas emitters, must be the flow of ambition, not the ceiling. US climate envoy John Kerry and his Chinese counterpart Xi Jinping unveiled a joint declaration late on Wednesday in which China, the biggest producer and user of coal, promised to accelerate its transition from the dirtiest fossil fuel. Greenpeace executive director Jennifer Morgan welcomed the deal, saying it was really important but said that two countries needed to go further. The deal has bolstered their COP26 UN climate summit as it enters two final days of tough bargaining to try to stop global warming becoming catastrophic. Observers have been worried before the announcement that Chinese President Xi Jinping was not attending the talks in Glasgow and Beijing had made no substantial new pledges. In the US and China work together on climate change at a time when the two countries and the broader scheme of things are at great odds is essential and so that is a good reset I would say of that relationship but it has to be the floor of ambition not the ceiling. So I think it's really important now they've said that they will both commit to improving NDCs in the 2020s they've both said they recognize the gap in between what national commitments are there now and where we need to get for 1.5 so we need each of them to work here to an outcome that comes back next year to strengthen national commitments and policies and comes back every year after that. I think one of the most important parts of the deal between the United States and China is the timing. It was really important that this come out in his last few days of COP because at a moment when it has been a long haul in these negotiations and everyone needed this positive signal that these two big emitters are going to step up they have agreed to work together we have a lot of details to hash out it is not a simple declaration but that step is there and it's a good first step.
