AR6 Synthesis Report
The IPCC is currently in its Sixth Assessment cycle. During this cycle, the Panel will produce three Special Reports, a Methodology Report on national greenhouse gas inventories and the Sixth Assessment Report (AR6). The AR6 will comprise three Working Group contributions and a Synthesis Report.
The AR6 Synthesis Report will integrate and synthesize the contributions from the three Working Groups that will be rolled out in 2021 into a concise document suitable for policymakers and other stakeholders.
It will be finalized in the first half of 2022 in time for the first global stocktake under the Paris Agreement.
Scoping
Scoping of the Synthesis Report to Sixth Assessment Report
A scoping meeting to draft the outline of the Synthesis Report will be held in 2019. During its 56th Session, the IPCC Bureau, established a Scientific Steering Committee to undertake the scoping of the Synthesis Report of the Sixth Assessment Report.
Scoping of the Working Group contributions to the Sixth Assessment Report
The meeting to draft the outline of the Sixth Assessment Report took place in Addis Ababa (Ethiopia) from 1 to 5 May 2017. The draft outlines were approved by the Panel when it met for its 46th Session in September 2017 in Montreal (Canada). During that Session, the Panel also considered a document IPCC-XLVI/Doc. 6 on cross cutting issues and the AR6 Synthesis Report.
To identify policy relevant questions and scientific and technical topics to be addressed in the AR6, on 21 September 2016, the IPCC Secretariat sent out a pre-scoping questionnaire to governments and observer organizations in September 2016. The responses were synthesized and made available to the participants of the AR6 Scoping meeting to draft the outlines and the Panel.
