Synthesis Report Home

SRAR5The Intergovernmental Panel on Climate Change (IPCC) has been established by World Meteorological Organization (WMO) and United Nations Environment Programme (UNEP) to assess scientific, technical and socio-economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. It is open to all Members of the UN and of WMO.

 

Scope

As defined in the IPCC procedures, the Synthesis Report (SYR) synthesizes and integrates material contained within IPCC Assessment Reports and Special Reports. The SYR should be based exclusively on material contained in the three Working Group Reports and Special Reports produced during the 5th or previous Assessment Cycles. It should be written in a “non-technical style suitable for policymakers and address a broad range of policy-relevant, but policy-neutral questions”, as stated in the procedures of IPCC Reports. The SYR should be largely self-contained, but guide readers to the underlying material if they wish to look further.
 
The primary audience for the SYR will be policymakers, in particular from governments, advisors to policymakers, and experts. However, it is recognized that others will also make use of the report.
 
The proposed SYR will consist of two parts:
1. Summary for Policymakers (SPM): up to 8 pages of text excluding the tables, maps, boxes and figures  
2. Longer Report: up to 30 pages of text excluding the tables, maps, boxes and figures.

The SYR publication will also contain annexes such as a glossary, list of authors, reviewers, Review Editors, and an index.   
 
The outline for the AR5 SYR was decided by the Panel at its 32nd session. The decided outline consists of four topics with a list of bullets for each, and an additional box. Flexibility is provided to the SYR writing team in the development of the list of bullets, which are provided here as guidance, and not as a constraint. The IPCC Chair will report to the Panel on the evolution of the outline of the SYR after the Zero Order Draft has been produced.

 

History

At 28th Session of the IPCC, Budapest, 9-11 April 2008 the Panel agreed to have a SYR for the Fifth Assessment of the IPCC. At its 30th Session, Antalya, 21-23 April 2009 the Panel agreed that the process of the SYR of the Fifth Assessment Report (AR5) should start with a scoping meeting. In line with that decision, a broad outline for the AR5 Synthesis Report was developed at the AR5 Scoping Meeting held in Venice, 13-17 July 2009. A meeting especially dedicated to the Synthesis Report, the Scoping Meeting for the Synthesis Report, was held in Liège, Belgium from 24-27 August 2010. At its 32nd Session, Busan, 11-14 October 2010, the Panel decided on the outline and time schedule for the Synthesis Report. Implementation of these decisions were considered at the 34th Session of the IPCC, Kampala, 18-19 November 20112. At this session, the Panel discussed the provisional time schedule, and agreed on the composition and selection criteria for establishing a writing team of the Synthesis Report. It was decided that the Chair, in consultation with the Working Group Co-Chairs, would nominate the candidates for the Synthesis Report Core Writing Team. The 45th Session of the Bureau of the IPCC, Geneva, 13-14 March 2012, decided on the selection of this team.
