IPCC AR5 Synthesis Report Plenary Approval Session

IIASA researchers are taking part in the plenary meeting to approve the Synthesis Report for the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5).

IIASA Energy Program Director Keywan Riahi and Transitions to New Technologies Program researcher Luis Gomez Echeverri are core writing group team members for Working Group III of the report, which covered climate mitigation and adaptation. Riahi will attend the meeting along with IIASA Energy Program researcher Joeri Rogelj, who is an extended core writing team member for the Working Group. 

According to the IPCC:  

"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 inthe procedures of IPCC Reports. The SYR should be largely self-contained, but guide readers to the underlying material if they wish to look further."

Following the end of plenary session on 2 November, the Synthesis Report will be released on the IPCC Web site

IIASA is a key contributor to the IPCC AR5 as well as previous reports: researchers from the Energy, Mitigation of Air Pollution and Greenhouse Gases, Risk, Policy, and Vulnerability, Transitions to New Technologies, and World Population Programs served as authors in all three Working Groups of the IPCC AR5, which was released in three volumes over the last year. The Institute has also contributed extensively to the formation of the new Shared Socioeconomic Pathways (SSPs), which will serve the scientific community and the IPCC for an integrated assessment of climate change impacts, adaptation and mitigation in the future.

On 2 November, a press conference took place to highlight the release of the synthesis report.
