Improvement of Nordic Emission Models for Solvent Use in Selected Sectors

image of Improvement of Nordic Emission Models for Solvent Use in Selected Sectors

This project considers the NMVOC emission inventories for solvent use that are used by the five Nordic countries for reporting to e.g. United Nations Framework Convention on Climate Change (UNFCCC), the European Commission and UNECE-Convention on Long-Range, Transboundary Air Pollution (CLRTAP). The project covers the entire solvent use sector, however, special attention has been given to domestic use. All the major codes associated with emission reporting and registration of chemical substances have been collected and compared. Emission factors have been presented for source categories and specific chemical substances, when possible. For the entire solvent sector 94 different combinations of SNAP/CORINAIR, CRF, NFR, RAINS/GAINS and NACE codes have been identified. UCN and emission factors are assigned for each combination on a country specific level. The purpose of this project has been to present existing data in the most transparent way in order to share, compare and improve data and methodologies. The results can be used for different purposes, e.g., facilitate assignment of specific emission factors to sources and substances, extrapolate activity data and/or emission factors between code systems, filling data gaps and identify key source categories.



Country specific linking of codes and emission factors

In this chapter each country presents the use category codes (UCN) and emission factors that correspond to the general linking of codes, described in the previous chapter. For Norway, Sweden and Denmark the NACE and UCN codes are used in the national registration system for solvents and solvent containing products and are applied in the emission inventories. Finland and Iceland use statistical data or data from the reports by operators and information from surveys. The id number refers to the general code linking described in the previous sector. For some countries the listed relationships and emission factors are to a high degree implemented in the current method, whereas for others there will be improvements in the coming inventories.
