The interplay between procedure and substance has not been a major point of contention for international environmental lawyers. Arguably, the topic’s low profile is due to the mostly uncontroversial nature of the field’s distinction between procedural and substantive obligations. Furthermore, the vast majority of environmental law scholars and practitioners have tended to welcome the procedural features of multilateral environmental agreements and their potential to promote regime evolution and effectiveness. However, recent developments have served to put the spotlight on certain aspects of the procedure substance topic. ICJ judgments revealed ambiguity on aspects of the customary law framework on transboundary harm prevention that the field had thought largely settled. In turn, in the treaty context, the Paris Agreement’s retreat from binding emissions targets and its decisive turn towards procedure reignited concerns in some quarters over the “proceduralization” of international environmental law. The two developments invite a closer look at the respective roles of, and the relationship between, procedure and substance in this field and, more specifically, in the context of harm prevention under customary and treaty law.

The second edition of this leading reference work provides a comprehensive discussion of the dynamic and important field of international law concerned with environmental protection. It is edited by globally-recognised international environmental law scholars, Professor Lavanya Rajamani and Professor Jacqueline Peel, and features 67 chapters authored by 76 renowned experts in their fields. The Handbook discusses the key principles underpinning international environmental law, its relevant actors and tools, and rules applying in its substantive sub-fields such as climate law, oceans law, wildlife and biodiversity law, and hazardous substances regulation. It also explores the intersection of international environmental law with other areas of international law, such as those concerned with trade, investment, disaster, migration, armed conflict, intellectual property, energy, and human rights. The Handbook sets its discussion of international environmental law in the broader interdisciplinary context of developments in science, ethics, politics and economics, which inform the way in which environmental rules are made, implemented, and enforced. It provides an introduction to the foundations of international environmental law while also engaging with questions at the frontiers of research, teaching, and practice in the field, including the role of Global South perspectives, the contribution made by Earth jurisprudence, and the growing role of a diverse range of actors from indigenous peoples to business and industry. Like the first edition, this second edition of the Handbook is an essential reference text for all engaged with environmental issues at the international level and the applicable governance and regulatory structures.

This Oxford Handbook examines the sources of international law, how the understanding of sources changed throughout the history of international law; how the main legal theories understood sources; the relationship between sources and the legitimacy of international law; and how sources differ across the various sub-areas of international law.

Taking stock of all the major developments in the field of international environmental law, this text explores core assumptions and concepts, basic analytical tools and key challenges.

A perfect introduction to climate change law, this textbook offers students and scholars an overview of the international law governing this fundamental issue. It demonstrates how to interpret the language used in the applicable instruments and conventions, and sets climate change law in its broader international legal context.

A concise, clear, and legally rigorous introduction to international environmental law and practice covering the very latest developments.

This Handbook is the first comprehensive account of comparative environmental law. It examines in detail the methodological foundations of the discipline as well as the substance of environmental law across countries from four vantage points: country studies from all continents, responses to common problems (including air pollution, water management, nature conservation, genetically modified organisms, climate change and energy, chemicals, waste), foundational components of environmental law systems (including principles, property rights, administrative and judicial organisation, command-and-control regulation, market mechanisms, informational techniques and liability mechanisms), and common interactions of environmental protection with the broader public, private, and criminal law contexts. The volume brings together the foremost authorities in this field from around the world to provide a concise, self-contained, and technically rigorous account of environmental law as a single overall system.
