Sixth Assessment Report cycle

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).

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.

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 in early September 2017 in Montreal (Canada).

A scoping meeting to draft the outline of the Synthesis Report will be held in 2019.

The three Working Group contributions to AR6 will be finalized in 2021 and the AR6 Synthesis Report in the first half of 2022 in time for the first UNFCCC global stocktake under the Paris Agreement in 2023

For detailed information on the delivery of the AR6 cycle in 2018, see the Strategic Planning Schedule (updated: 19 December 2017)
