Fuel consumption for the Swedish fishing fleet 1990-2004 has been estimated using statistics from the Swedish National Board of Fisheries on installed engine power. An additional estimation method was also described. Data on installed power was available for the years 1995-2004, and estimates 1990-1994 have been calculated by extrapolation. Thermal values and emission factors are based on a study conducted by SMED on behalf of the Swedish EPA in 2004. In order to fit the national fuel sales statistics, the diesel oil consumption was adjusted according to the national allocation model for international reporting. The adjusted fuel consumption accounted for about 68 700 – 93 900 m3, corresponding to about 187 – 256 ktons CO2.
