Documentation of methodologies for estimating emissions of greenhouse gases and long-range transboundary air pollutants

The Norwegian emission inventory 2008

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), Hoem (2006) and Aasestad (2007). The most important changes since last year is a revised method for calculation of CH4 and N2O emissions from ferroalloy production, revised N2O figures from one chemical plant for most years since 1990, increased emission figures for CH4 for all years since 1990 due to corrections of Statistics Norway's waste statistics and inclusion of N2O emissions from human sewage from the part of the population that is not connected to wastewater treatment plants. In addition there have been several minor changes in the figures, e.g., some figures reported from plants to the Norwegian Pollution Control Authority have replaced earlier reported figures. Chapter 8 Recalculation is updated.
