The pristine Arctic is an increasingly important region facing major challenges caused not only by the effects of climate change, but also by a growing interest in its living and non-living resources, its attraction as a new destination for tourism, and as a route for navigation. In particular the increase of commercial shipping leads to significant positive economic prospects but, at the same time, carries considerable risks for the fragile Arctic environment and the well-being of the local population, including indigenous people. By taking the example of the International Code for Ships Operating in Polar Waters, which was recently concluded under the auspices of the International Maritime Organization, it will be shown how instruments of international law are necessary and adequate to ensure that all those engaged in shipping and maritime transportation in the Arctic comply with strict standards of safety and environmental protection. In addition, remaining regulatory gaps will be revealed and possible solutions will be addressed.
