ABSTRACT
This chapter focuses on the tension between sovereignty and transboundary environmental concerns that come together in the concept of environmental interdependence. It outlines of the literature that addresses the politics of environmental interdependence. The 'problem-solving' strand of this literature tends to naturalize both the political and ecological facet of the essentially spatial notion of environmental interdependence. The chapter demonstrates the production of environmental boundaries in a cursory case study of the development of environmental cooperation in the Baltic Sea area. It suggests that environmental politics not only is critically dependent on a discourse closure to put policymaking on tracks, it also dependent on a spatial enclosure to situate the problem in question. One should also ask whether the drawing of inclusionary environmental boundaries serve additional - or even unrelated - purposes to those of environmental care. Environmental scientists may be able to devise convincing methods for the delineation of ecosystems.
