This is the fifteenth volume in the Papers on International Environmental Negotiation series published by the MIT-Harvard Public Disputes Program at Harvard Law School. The five papers in this volume pursue four themes that the editors view as central to improving the global "system" we use to generate and enforce multilateral environmental agreements: (1) the increasing importance of non-governmental actors in both formulating and implementing transboundary environmental agreements; (2) the need for better balance between "science" and "politics" in defining and responding to resource management problems that require transboundary cooperation; (3) the need for futher capacity-building to ensure that all relevant stakeholder groups are equipped to participate in the public-private partnerships, incentive systems, reporting mechanisms, and evaluating efforts needed to ensure effective implementation; and (4) the need for an elaborate system of interlocking public, private, and voluntary elements to achieve compliance without enforcement, which is all that the international system allows.
