The Norwegian Emission Inventory 2016. Documentation of methodologies for estimating emissions of greenhouse gases and long-range transboundary air pollutants

Abstract

The Norwegian emission inventory is a joint undertaking between the Norwegian Environment 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 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 2016b and 2016a).

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 2016b) for documentation on this topic.
