Gazprom, the Russian state owned energy company, is planning several re-routings of Nord Stream, the controversial Baltic gas pipeline, for environmental and political reasons. The pipeline is aimed at reducing Russia’s dependence on the energy transit countries of Ukraine and Belarus, giving it better access to Western Europe. Re-routing the section passing between the Danish and Polish parts of the Baltic Sea is intended to minimise the environmental impact and avoid a munitions dump site in Denmark. The part of the route that passes under Finnish, Estonian and Swedish waters is also causing difficulty, as it passes through internationally recognised and protected areas of World War II munitions dumping sites.
