The CCXG organises global forums and other events that bring together negotiators and experts from developed and developing countries to engage constructively on key topics relevant to the international climate change negotiations in an informal space. The CCXG also develops impartial technical analyses every six months to inform these discussions.
Climate Change Expert Group
The Climate Change Expert Group (CCXG) works to enhance understanding of specific topics relevant to the UN climate change negotiations and for implementing the Paris Agreement. Established in 1993, CCXG activities are jointly supported by the Organisation for Economic Co-operation and Development (OECD) and the International Energy Agency (IEA).

Our impact
Over the years, CCXG work has helped to inform discussions among countries and shape decisions adopted at UN climate change conferences (Conference of the Parties (COP). Recent examples include:
- At COP28, the decision on the Global Stocktake (GST) reflects options discussed in CCXG analysis including how to take forward GST outcomes and maintain political momentum through collaboration between the COP28-29-30 Presidencies.
- At COP26, CCXG analysis helped to shape decisions on Article 6 and common reporting tables under the Enhanced Transparency Framework of the Paris Agreement.

"The CCXG has been for many years a source of highly influential analysis and debate on key topics of the climate change negotiations. The urgency of making progress in the global response to climate change makes this contribution even more relevant and necessary."
