Weekly Bulletin issue no. 1, 1999 <sti>Stikktittel Emissions to air from foreign ships in Norwegian waters, 1996 and 1997:

Large emissions from foreign ships

In 1997, foreign ships in Norwegian waters burned more than 278,000 tonnes of fuel, around a quarter of what Norwegian ships used. Emissions of sulphur dioxide (SO2) from foreign ships calling on Norwegian ports totalled about 6,000 tonnes in 1996. By comparison, Statistics Norway has previously estimated that SO2 emissions from the Norwegian domestic fleet serving ports along the coast totalled 2,280 tonnes in 1993.

The figures show that foreign ships discharge more than twice as much SO2 as Norwegian ships, and more than all other Norwegian transport activities put together. There are, however, great uncertainties connected with the SO2 emission statistics from the foreign ships. That is because the estimates are based on the assumption that ships with engines larger than 2,000 kW burn heavy oil with a sulphur content of 2.7 per cent (assumption from Lloyd's Register).

Major contributor to pollution

Emissions of SO2, nitrogen oxides (NOx) carbon dioxide (CO2) and particulate matter from the foreign ships are of such a magnitude that they can exacerbate the local quality of air, acidification and climate changes. Broken down, the emissions of SO2, NOx, particulate matter and CO2 constitute 35, eight, seven and two per cent respectively of all Norwegian emissions.
