SBSTA 32 Invitation and IPCC Expert Meeting• The SBSTA 32 (June 2010), as part of its consideration of theuse of the 2006 IPCC Guidelines, invited the IPCC “toorganize an expert meeting to explore the need and ways toclarify methodological issues related to reporting on HWP,
wetlands and Soil N2O.
• In response to this, an IPCC Expert meeting on HWP, Soil
N2O and Wetlands was held in October 2010, which
considered the need for additional guidance on them in order
to fill gaps in the 2006 Inventory Guidelines.

IPCC Expert Meeting concluded: (1)• The meeting ... in general considered that the methodologicaladvice contained in the 2006 IPCC Guidelines still reflects the latest
science... Since the 2006 IPCC Guidelines were completed muchnew scientific information is now available about various wetlands
that enable emissions and removals to be estimated from wetland
restoration and rewetting especially for peatlands. The meeting
recommended that the IPCC provide additional methodological
guidelines for the rewetting and restoration of peatland; emissions
from fires, ditches and waterborne carbon; and constructedwetlands for waste water disposal, to fill gaps in the existing
guidelines.”

IPCC Expert Meeting concluded: (2)• The meeting also noted the availability of new information
across climate zones for wetlands and drainage addressedin other land use chapters and recommended developing
country and region specific EFs from this information.

SBSTA 33 Conclusions (Cancun, 2010)• “The SBSTA took note of the summary of the co-chairs of the IPCC
expert meeting on harvested wood products, wetlands and N2Oemissions from soils. Noting that science has developed in someareas with regard to wetlands, the SBSTA invited the IPCC toundertake further methodological work on wetlands, focusing on
the rewetting and restoration of peatland, with a view to filling inthe gaps in the 2006 IPCC Guidelines for National Greenhouse Gas
Inventories … in these areas and to complete this work for thethirty-ninth session of the SBSTA.” (i.e., in 2013)

IPCC Scoping meeting & Plenary Decision
to produce 2013 Supplement• In response to this SBSTA invitation, and utilising thecontingency funds in the 2011 budget, the “IPCC
Expert Meeting on Scoping Additional Guidance onWetlands” was held at the WMO in Geneva,
Switzerland from 30th March to 1st April, 2011.
• This meeting produced a draft Terms of Reference(ToR), including annotated chapter outline.
• The IPCC at its 33rd Session in Abu Dhabi (10th -13thMay 2011) decided to produce the “2013 Supplement
to the 2006 IPCC Guidelines for National Greenhouse
Gas Inventories: Wetlands”.

Work has started!
• On 1st June, IPCC issued its formal letter of invitation ofauthor nominations to its member Governments andinternational organizations. The Authors have been
selected by the Task Force Bureau on GHG Inventories.
• In accordance with the current IPCC Principles andProcedures, there will be four authors meetings and two
IPCC Reviews before the final Government consideration.
• This work will abide by the IPCC Principles andProcedures, including those new rules that may beadopted by the IPCC Plenary in the course of the 2013
Supplement.

First authors meeting held!
• On 30th October – 3rd November 2011, the first meeting ofCLAs and LAs was held at IGES, Japan.
