Sweden is a mature economy with a strong focus on renewable fuels and carbon reduction. Sweden's retail fuel market is highly consolidated, with the four main players accounting for approximately 90% of volume market share. A high degree of market concentration limits the opportunity for further expansion through M&A by the incumbent players. Sweden's overall refining capacity exceeds domestic demand and the major refining hub in the west is somewhat removed from the main consumption centre in the east. These imbalances result in a large proportion of Sweden's refined oil products being exported. Sweden also imports finished products to meet local demand in the east, especially from Finland. Retail service station numbers are in decline and the overall network contains a large percentage of automated outlets.
