Climate Change Expert Group (CCXG)


The Climate Change Expert Group (CCXG) is a group of government delegates and experts from developed and developing countries. The aim of the group is to promote dialogue on and enhance understanding of technical issues in the international climate change negotiations. The group holds two seminars per year which bring together government representatives, the private sector and civil society in order to share information on climate policies and issues. The CCXG also develops papers in consultation with a wide range of countries.

The group is currently working on technical issues under discussion in the international negotiations towards a 2015 climate change agreement. More information on the CCXG flyer.
