- The Norwegian Emission Inventory
The Norwegian emission inventory is a joint undertaking between the Climate and Pollution Agency1 and Statistics Norway. Statistics Norway is responsible for the collection and development of activity data, and emission figures are derived from models operated by Statistics Norway. The Climate and Pollution Agency is responsible for the emission factors, for providing data from specific industries and sources and for considering the quality, and assuring necessary updating, of emission models like, e.g., the road traffic model and calculation of methane emissions from landfills. Emission data are used for a range of national applications and for international reporting. The Climate and Pollution Agency is responsible for the Norwegian reporting to United Nations Framework Convention on Climate Change (UNFCCC) and to United Nations Economic Commission Europe (UN-ECE).
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). LULUCF (land use, land-use change and forestry) is not considered in this report, see the National Inventory Report (Climate and Pollution Agency 2012) for documentation on this topic.
This report replaces the previous documentation of the emission model (Sandmo 2011), and is the latest annually updated version of a report edited by Britta Hoem in 2005. The most important changes since last year’s documentation are:
- Minor NOx emissions from production of rock wool, which previously not have been estimated, have been included
- Some factors for estimation of N2O from agriculture have been altered
- The emission factors for particles from wood waste have been increased significantly
There are no methodical changes in the present emission documentation. In addition to changes brought about by the mentioned causes, there are several minor changes in the emission figures, e.g. due to changes in figures on energy combustion. Chapter 8 Recalculations gives a more thorough description of changes in the most recent emission calculations.
1The Climate and Pollution Agency was up to 2010 called The Norwegian Pollution Control Authority, abbreviated SFT. In this publication, the previous name and abbreviation are used in some contexts, mainly in connection with references to publications.
