Shared State Responsibility for Land-Based Marine Plastic Pollution

Yoshifumi Tanaka

Plastic litter is introduced into the oceans from land-based sources located in many countries around the world. Marine plastic pollution may therefore be attributable to multiple states, resulting in shared state responsibility. This article discusses the issue of shared state responsibility for land-based marine plastic pollution by examining (i) primary rules of international law concerning the prevention of land-based marine plastic pollution; (ii) secondary rules of international law on this subject; and (iii) possible ways of strengthening the primary rules. It concludes that the barrier for the invocation of state responsibility may become higher in cases of shared state responsibility. Three cumulative solutions to this problem are proposed: elaborating the obligation of due diligence, strengthening compliance procedures, and interlinking regimes governing the marine environment and international watercourses.

Changing Paradigms in the Law of the Sea and the Marine Arctic

Tanaka, Yoshifumi

The existence of a sense of common or community interests is a prerequisite to establishing an order in a society, national or international. In this connection, it is notable that the protection of community interests is increasingly important in international law and the law of the sea is no exception. The increasing need for protecting community interests necessitates a new paradigm in the law of the sea. The legal issues regarding the marine Arctic should also be considered in the context of changing paradigms in the law of the sea. Thus this article seeks to overview principal issues of the international law governing the marine Arctic from the viewpoints of a dual paradigm, that is, the law of divided oceans (paradigm I) and the law of our common ocean (paradigm II).
