This paper aims to understand contemporary environmental statehood at the level of the regional seas (the North Sea, the Baltic, the Black Sea and the Mediterranean and the Arctic) and the high seas. The paper will analyse and understand the potential and limits of contemporary environmental statehood at territorial levels beyond the state, especially the multiple faced character of environmental states at the regional and the high sea (ranging from implementing environmental policies for their own territorial seas, intergovernmental bargaining to be just one of the players in a networked polity).
