By Tone Sutterud and Elisabeth Ulven for The Guardian – The Norwegian government is being sued by climate activists over a decision to open up areas of the Arctic Ocean for oil exploration, a move they say endangers the lives of existing and future generations. The plaintiffs, led by environmental organisations Greenpeace and Youth and Nature, will on Tuesday claim that the Norwegian government has violated a constitutional environmental law which guarantees citizens’ rights to a healthy environment. The law, known as Section 112, states: “Everyone has the right to an environment that safeguards their health and to nature where production ability and diversity are preserved. Natural resources must be managed from a long-term and versatile consideration which also upholds this right for future generations.” “We have for years tried to stop the expansion of Norway’s oil extraction, from both local and global considerations,” said Truls Gulowsen, head of Greenpeace Norway. “As far as granting concessions for the Arctic is concerned, not only have our objections been ignored and overrun, but the state has also paid no heed to the guidelines from their own appointed advisers, such as the polar institute and the environment agency, who both recommended that the majority of concessions in this area be turned down.” In fighting the case, Greenpeace is relying on the findings of the Intergovernmental Panel on Climate Change, which states that to meet the goals set out in the 2015 Paris accord, oil production must be wound down, not escalated.
