Climate Change 2014: Mitigation of climate change IPCC Working Group III Contribution to AR5

The Working Group III contribution to the IPCC Fifth Assessment Report (WGIII AR5) provides a comprehensive assessment of all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions, as well as activities that remove them from the atmosphere.

It draws on scientific literature accepted for publication prior to 4 October 2013. The WGIII Summary for Policymakers was approved at the Twelfth Session of Working Group III, held in Berlin, Germany, from 7 to 11 April, 2014. During the session, the IPCC plenary also accepted the underlying scientific and technical assessment, which stands at 2000 pages, including more than 700 pages of references.

Final Draft

All TS elements which have an exact counterpart in the SPM will be updated to exactly reflect any changes made to the SPM. All other TS elements will be carefully considered and updated as necessary to ensure consistency with the approved SPM.
