Abstract [en]

As part of an on-going project to improve the quality of Swedish marine emission reporting, SMED (Swedish Methodology for Environmental Data, a collaboration between the Swedish Environmental Research Institute, Statistics Sweden and the Swedish Meteorological and Hydrological Institute) has derived emission factors for ships (> 100 Gross Register Tonnage). The basis for this type of reporting is that only emissions derived from Swedish sold marine fuels are accounted for. This work presents the agglomerated emissions factors to suit available activity data (i.e. Swedish marine fuel sales) enabling total emissions for the period 1990 – 2002 to be calculated.

When tentatively comparing the new emission totals with those reported earlier (using older emission factor data), a striking difference is that SO2 emissions have been previously underestimated (ca. 5 times too small for International sea traffic). The new HC and CO emissions are however approximately half of those calculated earlier. For NOx, the older estimates agree reasonably well with the new estimates.

Abstract [sv]

Med syftet att förbättra den svenska rapporteringen av marina emissioner har SMED (Svenska Miljö Emissions Data, ett konsortium bestående av IVL Svenska Miljöinstitutet, Statistiska Centralbyrån och Sveriges Meteorologiska och Hydrologiska Institut) tagit fram emissionsfaktorer för fartyg (> 100 Brutto tonnage). Grunden för denna typ av rapportering är att endast emissioner från i Sverige sålda marina bränslen ingår. Detta arbete presenterar emissionsfaktorerna anpassade till aktivitetsdatan så att de totala emissionerna för perioden 1990-2002 kan beräknas.

Jämfört med de tidigare uppskattningarna (med de gamla emissionsfaktorerna) är SO2-emissionerna ca. fem gånger större baserade på denna studie. De nya HC- och CO-emissionerna är däremot ungefär hälften av de som har rapporterats tidigare. Vad gäller NOx-emissionerna finns det inga signfikanta skillnader mellan de gamla och nya beräkningarna.
