The Synthesis Report is the final product of the Sixth Assessment Report to be approved in September 2022. It synthesises and integrates the findings of all three Working Group contributions to the Sixth Assessment Report and the special reports that have been produced in this cycle

During the review, experts may comment on the structure and comprehensiveness of the report and suggest improvements on the presentation of materials graphically or through tables. They may also propose revisions, relevant additional papers with full citation, and shorten text without losing relevant information.
