Externa kostnader för luftföroreningar: kunskapsläget avseende påverkan på ekosystemet i Sverige, betydelsen av var utsläppen sker samt kostnader för utsläpp från svensk sjöfart


This report presents the basis and calculations for the subproject air pollution carried out within the framework of VTI’s second government commission on traffic economic costs (Samkost2). In this study, we have estimated marginal external costs of air pollution with the method developed and used in the EU for this purpose, the so-called “Impact Pathway Approach”, focusing on the importance and the impact on the ecosystem and emissions from shipping.

In the earlier study of air pollution in Samkost was concluded that a largely unexplored question was how much the transport sector contributes to secondary pollution and the impact these have on population exposure and impact on the ecosystem. It was found that this is an important issue because it is these pollutants that are the focus of the EU’s air quality policy. To carry out impact assessments of the proposals at EU level in this field, and to compare the results of different studies, it is important to clarify the pollution that has been the basis for the analysis.

For this reason, the focus of Samkost2 on air pollution became how to perform calculations for the secondary pollutants. There was also a desire to gain more knowledge about the marginal costs of emissions from Swedish shipping, and on how impacts on ecosystems can be included in these calculations. To carry out these calculations required information in the form of dispersion modelling. Therefore, SMHI was commissioned to provide data on emissions at sea and their dispersion. Due to time constraints, since this VTI’s commission had a deadline and dispersion modelling involves complex calculation that requires time, the calculations got adapted to the restrictions of the commission. Only emissions from Swedish shipping and not from the other modes were included. To get some information about geographical differences in the impact of emissions that occur in different places separate calculations for three different areas was conducted; Skagerrak and Kattegat, the Baltic Sea south of Åland and the Baltic Sea north of the Åland Islands. Specific effects, i.e. exposure, were only modelled for the population and not for different types of ecosystems.
