Good Climate Governance: Only a Fragmented System of International Law Away?

Fragmentation is the hallmark of international environmental law—it is both the key to its success and the pathway to its unraveling. Recognizing that law is an essential component of systems of supranational climate governance, addressing gaps between international legal systems is fundamentally important to the legitimacy of international law and to on‐going attempts to use international law as a central component in efforts to address climate change. This article analyzes developments in international environmental law with a view towards suggesting how efforts to develop an international climate change legal regime—and a broader system of global climate governance—highlight the pressing need to look more closely at the linkages between climate change and other areas of international law and to begin thinking about ways to minimize gaps and maximize cooperation among international environmental institutions and between international environmental law and other spheres of international law.
