The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body responsible for evaluating scientific work and data on climate change. 

The OCE became an IPCC Observer Organization during a vote at the end of the 53rd Session of the IPCC, which took place from March 22 to 26, 2021. As an Observer Organization, the OCE can now attend IPCC and working group meetings, propose experts for the examination and evaluation of projects, and be called on by the IPCC Secretariat to take part in working groups.

Since its creation, the OCE has worked closely with the various IPCC technical support teams on the production and validation of teaching resources based on the IPCC reports. The OCE aims to complement the publication of the reports with educational resources for teachers.

The OCE has been formally invited by the French ministry of Ecological Transition to become an official reviewer of the IPCC reports on education matters on behalf of the French government.

In addition, OCE and IPCC signed a memorandum of understanding in 2022 to continue exploring synergies between their work.
