IPCC Guidelines for National Greenhouse Gas Inventories:

Dear climate- Readers

The Intergovernmental Panel on Climate Change (IPCC) is pleased to announce that the government and expert review of the second order draft of the "2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands" (Wetlands Supplement) including the first draft of its Overview Chapter will begin on 11 February 2013 and end on 7 April 2013.

127 experts participated in the review of the first order draft, in which 5,055 comments were received. The author team has considered all the comments and worked on the second order draft which has been prepared for review by IPCC member governments and experts. The Wetlands Supplement will be available at the end of October 2013. 

Climate policy and global climate negotiations rely on a robust scientific foundation to produce sound results. The IPCC provides policymakers with regular assessments of climate science and its potential impacts, as well as assessments of the possibilities for mitigating climate change. The estimation of emissions and removals of greenhouse gases is one important basis for climate mitigation and the IPCC provides de facto international standards for such estimation, though highly technical work, while offering flexibility to take different national circumstances and capacities into account.

In 2010, the United Nations Framework Convention on Climate Change (UNFCCC) invited the IPCC to undertake further methodological work on wetlands, focusing on the rewetting and restoration of peatland, with a view to filling in the gaps in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006 IPCC Guidelines). In May the following year, during its 33rd Plenary meeting in Abu Dhabi, the IPCC asked its Task Force on National Greenhouse Gas Inventories (TFI) to undertake the work to develop additional national-level inventory methodological guidance on wetlands to address the gaps identified in the 2006 IPCC Guidelines.

Also at the request of the UNFCCC, the TFI is working on the "2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol", whose first draft is being reviewed by experts until 3 February 2013. It will also be available at the end of October 2013. 

Review is a vital part of producing methodology reports such as this one. Draft reports are subjected to a multi-stage review beginning with the review of a first order draft by scientific experts, followed by the review of a second order draft by governments and experts and a final round of government  comments prior to the approval session of the Panel. 

The IPCC seeks as broad a range of experts as possible, based on a self-declaration of expertise. A wide range of reviewers including those with expertise in wetlands, forests and wetland soils; the IPCC Guidelines; land use, land-use change and forestry; and inventory compilation are expected to participate in this review. Once registered, expert reviewers will be provided with the drafts that are confidential documents not to be cited, quoted or distributed.  The drafts, comments and responses are made public after the report or guidance is finalized.  

Experts interested in taking part in this review should register here . Registration will start on 4 February 2013 and will be open throughout the review period.
