An increase in global temperature of even 1.5°C could lead to irreversible impacts, and 2°C risks triggering catastrophic runaway climate change. Governments need to take action now to ensure emissions peak by 2015 and decline rapidly to zero by mid-century.

The window of opportunity for avoiding runaway climate change is closing rapidly. This document is a short version of the policy demands put forward by Greenpeace, for developing and industrialised nations to take concrete action at the climate summit in Copenhagen.
