Accidential oil spills (above 7 tonnes per spill) from tankers, combined carriers and barges in Europe

Key assessment

Pollution by oil spills worldwide has been reduced by 60 % since the 1970s. In the EU, major accidental oil spills (>20 000 tonnes) still occur at irregular intervals.

Oil spills from shipping - illegal discharges or from accidents - are an important source of pollution in sea areas. Worldwide estimates of oil pollution of sea areas show that transport contributed 22 % to total spills in 1973 (1.3 million tonnes out of 5.9 million tonnes), and 34 % in 1981 (1.1 million tonnes out of 3.2 million tonnes). Between 1973 and 1981, the quantities spilled during accidents were always below those spilled during operations. In 1989 transport-related oil spills were only a third of the 1973 estimate.
