The two principal aims with this project was to adjust the discrepancy between Swedish official air pollution emission projections and scenarios for Sweden developed by other international institutions, and to analyse the emission abatement potential in Sweden by 2030. Data used to support the Swedish official emission projections was collected and reformatted to enable a comparison with scenario data for Swedish emissions developed by IIASA. The results of this comparison were discussed with IIASA during the bilateral consultation carried out as a part of the on-going revision of the EU Thematic Strategy for Air Pollution. In parallel to this consultation, the potential for further emission abatement in Sweden by 2030 was analysed by interviewing representatives of power plants and large industrial facilities. The comparison with IIASA emission scenarios for Sweden identified that much of the differences between Swedish projections and IIASA emission scenarios originate from the transport sector, small scale domestic combustion in households, as well as from burning of agricultural waste. The potential for NOx emission abatement was estimated for the sectors: power plants; refineries; pulp & paper industries; and the iron & steel industry. If all plants in these sectors were to use the best available technology in 2030, NOx emissions could be reduced by some 13 kton NOx, or ?38% of the 35 kton emissions projected from these sectors by 2030. Abatement costs could in this project only be estimated for 2.3 kton. For these, the abatement cost would be ?170 million Swedish crowns per year.
