Book excerpt: Greening International Jurisprudence: Environmental NGOs before International Courts, Tribunals, and Compliance Committees examines how international judicial and quasi-judicial bodies enforce international environmental law, with particular consideration to the role of environmental NGOs. The analytical structure of the study is based on four aspects of discussion and research: the enforcement deficit in environmental law; global environmental governance and sustainable development; the proliferation of international judicial and quasi-judicial bodies; and deliberation and democratic global governance. Author Cathrin Zengerling analyses the institutional structure, as well as the environmental case law from a total of fourteen international courts, arbitral tribunals, and compliance committees with special focus on accessibility, comprehensiveness, and transparency. Underlying this analysis is the fundamental question of whether the respective body appropriately contributes to the realization of democratic governance for sustainable development. After presenting her core findings, the author provides concrete recommendations for future best practices and discusses the need for a new World Environment Court. Researchers, practitioners, and students of international environmental law will find an important, thought-provoking and timely new text in Greening International Jurisprudence: Environmental NGOs before International Courts, Tribunals, and Compliance Committees.
