These processes and procedures are constantly being reviewed and updated to ensure that they remain strong, transparent and reliable. For recent changes to IPCC procedures and related information see Review of Processes and Procedures (English) which covers all the recent changes to IPCC procedures approved by the Panel in the period 2010-2012.
