IPCC accepts two methodology reports

IPCC Press Release
18 October 2013
Batumi, Georgia

The Intergovernmental Panel on Climate Change (IPCC) has accepted two new Methodology Reports prepared by its Task Force on National Greenhouse Gas Inventories (TFI).

The two reports — the 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands (Wetlands Supplement) and the 2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol (KP Supplement) – were accepted at the IPCC’s 37th Session, held in Batumi, Georgia, on 14-18 October 2013.

“By filling most of the gaps for wetlands reporting in previous IPCC Guidelines, countries can now present their inventories in a more complete way, which is one of the IPCC criteria for reporting greenhouse gas inventories,” said Thelma Krug, one of the Co-Chairs of the TFI.

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, through highly technical work.

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 the 33rd Session of the IPCC, the IPCC asked the 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.

In December 2011, the Parties to the Kyoto Protocol to the UNFCCC invited the IPCC to review and, if necessary, update supplementary methodologies for estimating anthropogenic greenhouse gas emissions by sources and removals by sinks resulting from land use, land-use change and forestry (LULUCF) activities, on the basis of, inter alia, Chapter 4 of IPCC’s 2003 Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG-LULUCF).

In response, in June the following year, at its 35th Session, the IPCC asked the TFI to produce the KP Supplement. The KP Supplement has been finalized in time for use by the Parties to the Kyoto Protocol in the second commitment period of the protocol, running from 2013 to 2020.

“These two reports are the products of very strong  international teams of authors and their dedication,” said Taka Hiraishi, the other Co-Chair of the TFI. “Their devotion of many hundreds of hours, for some more than a thousand hours, on top of their own research time, made up these two reports.”

Future work of the IPCC

At the conclusion of each assessment cycle, the IPCC generally reflects on the report preparation process and draws lessons for the IPCC’s future work programmes and processes. The 37th Session formed a Task Group on the future work of the IPCC, agreed on its terms of reference and asked it to prepare a report presenting options and/or recommendations for the 41st Session of the IPCC to be held in the first quarter of 2015, in time for the expected election of a new IPCC Bureau. This Task Group will be chaired by New Zealand and Saudi Arabia and will consider the future products of the IPCC; the appropriate structure and modus operandi for the production of these IPCC products; and ways to ensure enhancement of the participation and contribution of developing countries in the future work of the IPCC.

Among other work, the 37th Session reviewed the progress by its Working Groups on the preparation of the Fifth Assessment Report and related outreach activities, as well as programme and budget matters.
