The article seeks to make a modest effort in making sense of the international environmental law-making process. It comprises the subtle normative process currently at work, including 'global conferencing' technique resorted to by the UN General Assembly, how it draws upon the basic legal underpinnings of international law, the unique treaty-making enterprise at work, and what this enormous legal churning process portends for the protection of the global environment at this critical time of perplexity in the Anthropocene epoch. It calls for taking serious cognizance of mass destruction of plant and animal species, heavy pollution of fresh water resources, choking of the oceans with plastic and other litter, and alteration of the atmosphere, among other lasting impacts that imperil our only abode Earth. International environmental law-making process is ad hoc and piecemeal and is generally understood to be the product of a lack of a single, central specialized institution having expertise on the subject, scientific uncertainty on many environmental issues, and the hard-headed economic interests of sovereign states. Still, the international environmental law-making process with its inherent resilience could possibly be able to adapt to the vagaries of scientific assessments and the political realities of in the future.
This essay aims to launch the proceedings of international law on a high note, and to suggest that many common impressions of it are wrong in general, and particularly wrong in the context of international environmental law. Even more particularly, multilateral environmental agreements (MEAs) illustrate the maturation and sophistication of international environmental law. If anything, the diversity and flexibility of compliance approaches under MEAs highlight the limited purchase of simple dichotomies such as "binding vs. non-binding" or "enforcement vs. ineffectiveness". The essay begins by exploring the concept of "enforcement" in international law in general. It suggests that a concept of enforcement as imposition of legal sanctions, or penalties, is unduly narrow. The essay then canvasses some of the main theoretical assumptions about international law and compliance. An exploration of this theoretical context illuminates the reasons underlying common misconceptions about international law and its enforcement, and helps put in perspective the evolution of approaches to compliance in international environmental law. Finally, against the backdrop of these general considerations, the author examines key features of the approaches to compliance and enforcement in international environmental law and MEAs. The aim is to provide a 'bigger picture', a context for the detailed discussions of compliance mechanisms that make up the bulk of the conference proceedings.
