The Norwegian emission inventory 2007

The Norwegian emission inventory is a joint undertaking between the Norwegian Pollution Control Authority and Statistics Norway. The Norwegian Pollution Control Authority is responsible for the emission factors and for providing data from specific industries and sources, while emission figures are derived from models operated by Statistics Norway. Statistics Norway is responsible for developing the emission models, for the collection and development of activity data, and for the calculations. Emission data are used for a range of national applications and for international reporting.

This report documents the methodologies used in the Norwegian emission inventory of greenhouse gases (GHG), acidifying pollutants, heavy metals (HM) and persistent organic pollutants (POPs). The documentation will also serve as a part of the National Inventory Report submitted by Norway to the United Nations Framework Convention on Climate Change (UNFCCC), and as documentation of the reported emissions to UNECE for the pollutants restricted by CLRTAP (Convention on Long-Range Transboundary Air Pollution).

This report replaces the previous documentations of the emission model, Rypdal (1993), Rypdal (1995b), Flugsrud et al. (2000), Hoem (2005) and Hoem (2006). The most important changes since last year is a new methodology for estimation of emissions of HFCs and PFCs from products, improvements in Statistics Norway's waste statistics and updating of the decomposition time for wood, paper and easy degradable waste and the reappraisal of the allocation of auto diesel oil among user group. In addition more figures reported to the Norwegian Pollution Control Authority has replaced earlier estimated figures, some emission factors has been updated and some errors in emission factors has been corrected. Chapter 8 Recalculation is updated.
