About the Expert Review

The Expert Review of the FOD is a key element of the IPCC assessment process, helping to ensure that the report provides a balanced and comprehensive assessment of the latest available scientific findings. The IPCC Procedures state that the expert review process shall be objective, open and transparent, with a wide circulation that aims to involve as many independent experts as possible, seeking a wide range of views, expertise, and geographical representation.

Registration closes on 25 September 2026 at 10.59pm BST. Additional information on the role of an Expert Reviewer can be found in Annex 1 of Appendix A to the Principles Governing IPCC Work.
The UK is committed to diversity and inclusion in the IPCC process.
