International environmental law is often closer to home than we know, affecting the food we eat, the products we buy, and even the air we breathe. Drawing on more than two decades of experience as a government negotiator, consultant, and academic, Daniel Bodansky brings a real-world perspective on the processes by which international environmental law develops, and influences the behavior of state and non-state actors.

In self-contained chapters that offer a clear guide to a complex field, Bodansky answers fundamental questions about how international environmental law works. What role can law play in addressing global environmental challenges such as climate change, ozone depletion, and loss of biodiversity? How do environmental problems come onto the international agenda? What are the obstacles to international cooperation, and what can international environmental law do to address them? How do international rules develop? How are they put into practice and what makes them effective?
