Consequences for the Swedish Greenhouse Gas Inventory from using the 2006 IPCC Guidelines

About a year ago IPCC published the new 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006 GL), which were prepared by the IPCC in response to an invitation by SBSTA. At SBSTA 26 in spring 2007 the 2006 GL were welcomed and discussed (INF/SBSTA/2007/L.5). The conclusions state the need to consider the 2006 GL in context of the revision of the new reporting guidelines, and encouraged Parties, in position to do so, to gain experience and submit information on their experience. The start of the process to revise the reporting guidelines is expected to start in the fall of 2009.

The Swedish National System entails distributed responsibilities between several authorities. The Swedish EPA, which is responsible for the final compilation of the inventory and coordination of the National System, has initiated this study in order to gain experiences and to assess consequences for the Swedish inventory system from a possible future use of the new IPCC Guidelines. The Swedish EPA intends to have a dialogue with national authorities, the Ministry of Environment and other EU member states about the results.

Overall objective

The overall objective of this study was to increase the knowledge about the 2006 IPCC Guidelines and estimate impacts on the Swedish GHG inventory if applied.

Detailed objectives

Assess, identify and document if and for which areas and source categories changes or adjustments in the Swedish inventory work will be necessary if the IPCC 2006 Guidelines become mandatory.

  1. Assess if possible changes in methodology in order to be in line with the 2006 Guidelines may result in quantitative changes in the emission estimates compared to the present Swedish methods.
  2. Assess and identify if the 2006 Guidelines imply any changes for the national authorities concerned as part of the National System.
  3. Indicative cost estimates for introducing new methodologies according to the 2006 IPCC Guidelines, where relevant.
  4. Identify and describe changes in the revised reporting format.
  5. Evaluate positive or negative consequences for the inventory and the quality of reported emissions as a result of the revised reporting format.
