Time is running out to keep the global temperature rise below 1.5 degrees Celsius and adapt to the impacts of climate change. While this reality has been widely acknowledged, global ambition is still not strong enough and the pace of action is too slow to achieve the objectives of the Paris Agreement.

The world is facing an existential threat. But it is also clear that without equity, ambition is not possible. The ongoing CoP25 must not duck this question any further says Centre for Science and Environment in its new position paper "COP 25: What the world must do"

The 25th Conference of the Parties (COP25) to the UN Framework Convention on Climate Change in Madrid, Spain, this December will be a turning point for global action towards the Paris Agreement. COP25 must build on the political momentum generated by the UN Secretary-General’s Climate Action Summit held on 23 September in New York.

Almost three-quarters of the 184 climate pledges made under the Paris Agreement aimed at curbing greenhouse gas emissions are inadequate to slow climate change, and some of the world's largest emitters will continue to increase emissions, according to a panel of world-class climate scientists.
