Intergovernmental Panel for Climate Change

What is the IPCC?

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for the assessment of climate change.

The IPCC is an intergovernmental body and focuses on the science-policy interface, i.e. handing over scientific information so that it can underpin government decisions on how to address climate change.

It is open to all member countries of the United Nations (UN) and WMO.

Reports are written by scientists drawn from around the world based on their expertise and geographical balance. 

Governments participate in the review process and the plenary Sessions, where main decisions about the IPCC work programme are taken and reports are accepted, adopted and approved.

The IPCC provides guidelines and best practice advice on preparing greenhouse gas emissions inventories through its Task Force on National Greenhouse Gas Inventories.
