The Norwegian Emission Inventory 2014
Documentation of methodologies for estimating emissions of greenhouse gases and long-range transboundary air pollutants
Denne publikasjonen finnes kun på engelsk
The Norwegian emission inventory is a joint undertaking between the Norwegian Environment Agency 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 Norwegian Environment 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 Norwegian Environment 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). The Norwegian Environment annually publishes reports prepared as a part of these reportings: National Inventory Report (NIR) for UNFCCC and Informative Inventory Report (IIR) for UN-ECE (Norwegian Environment Agency 2014b and 2014a).
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 (Norwegian Environment Agency 2014b) for documentation on this topic.
This report is the latest annually updated version. The most important changes since last year’s documentation are:
- Emissions of N2O and NH3 from use of sewage sludge applied on parks and green spaces, cover on landfills, used as fertiliser and other use have been included for all years since 1990
- Emissions of NMVOC and particles from handling of coal at Spitsbergen are included for the first time
- The method for calculating NOx emissions from diesel engines at offshore installations has been revised
Previous editions of this report included a detailed description of recalculations in the most recent emission figures. These recalculation descriptions can now only be found in the Informative Inventory Report (Norwegian Environment Agency 2014a) and the National Inventory Report (Norwegian Environment Agency 2014b).
