UNFCCC Publishes GHG Synthesis and Assessment Report
story highlights

The synthesis and assessment report contains greenhouse gas (GHG) inventory information compiled in tabular format.

The tables provide comparisons of implied emission factors and activity data as reported in the common reporting format (CRF), data from international sources, emissions, information on methods used and emission factors as reported by parties in Summary Table 3 of the CRF, and other information relating to GHG inventory estimates.

UNFCCC27 June 2011: The UNFCCC Secretariat has published the synthesis and assessment report (FCCC/WEB/SAI/2011) on the greenhouse gas (GHG) inventories submitted in 2011.

The synthesis and assessment is prepared in two parts. Part I provides information to allow comparisons across Annex I parties, as well as descriptions of common methodological issues. Part II provides a preliminary analysis of individual Annex I party inventories. In particular, it identifies outstanding issues requiring clarification during the individual review stage of the process. Part I of this synthesis and assessment report has been sent to parties for comment prior to publication on the UNFCCC website. Part II will be sent to the respective parties for comments and, together with the comments received, will be provided to the corresponding expert review team (ERT) as input for the individual review. Part II will not be published on the UNFCCC website.

This synthesis and assessment report contains GHG inventory information compiled in tabular format. The tables provide comparisons of implied emission factors and activity data as reported in the common reporting format (CRF), data from international sources, emissions, information on methods used and emission factors as reported by parties in Summary Table 3 of the CRF, and other information relating to GHG inventory estimates. Where possible, this information is provided for all parties for both the base year or period, and for the year 2009. For some categories, however, trend comparisons across all parties were not possible due to the lack of data or use of notation keys for some or all of the years in the time series.

The inventory data were analyzed according to the sectors, sub-sectors and categories specified in the CRF, which correspond to those of the Revised 1996 Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories and the IPCC Good Practice Guidance for Land Use, Land-use Change and Forestry (LULUCF).
