The Intergovernmental Panel on Climate Change (IPCC) will consider the Working Group II contribution to the Fifth Assessment Report, covering impacts, adaptation and vulnerability, in Yokohama, Japan, on 25-29 March 2014. The Working Group session will approve the respective Summary for Policymakers and accept the full report. An IPCC Plenary session will follow the Working Group session to accept the action taken by the Working Group.

Late in February, on the 28th, the IPCC released two new Methodology Reports today that were prepared by its Task Force on National Greenhouse Gas Inventories (TFI). The Wetlands Supplement extends the content of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006 IPCC Guidelines) by filling gaps in coverage and providing updated information reflecting scientific advances, including updating emission factors. It covers inland organic soils and wetlands on mineral soils, coastal wetlands including mangrove forests, tidal marshes and seagrass meadows and constructed wetlands for wastewater treatment. The coverage of the 2006 IPCC Guidelines on wetlands was restricted to peatlands drained and managed for peat extraction, conversion to flooded lands, and limited guidance for drained organic soils.

The Kyoto Protocol (KP) Supplement provides supplementary methods and good practice guidance for estimating anthropogenic greenhouse gas emissions by sources and removals by sinks resulting from land use, land-use change and forestry (LULUCF) activities under Article 3, paragraphs 3 and 4, of the Kyoto Protocol for the second commitment period. It revises and updates Chapter 4 of the Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG-LULUCF) which provides supplementary methods and good practice guidance related to LULUCF activities based on the general greenhouse gas inventory guidance provided in its other chapters and the rules governing the treatment of LULUCF activities in the first commitment period of the Kyoto Protocol.
