The UNECE region is a major source of greenhouse gas emissions, responsible for 34% of the world’s CO2 emissions from fossil fuel combustion. The people of the region are increasingly feeling the impacts of climate change - from wildfires to flooding, heatwaves and drought. 

Through its norms, standards, conventions and policy assistance, UNECE provides practical tools to support countries in their climate change mitigation and adaptation efforts, to leverage financing, and to strengthen collaboration.
