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.
