Sustainable development has become a central objective in national and international policy of development and the environment. Increasingly, it also marks international and national law. In this book, scholars in environmental law discuss legal theories of sustainable development and how it may be operationalized. The book also looks at topics related to its development in international law, European law, international trade law, investment law, and within the climate regime. Sustainable Development in International and National Law marks the 20th anniversary of the 1987 report of the "Brundtland Commission" which brought the concept of sustainable development to the forefront of the international agenda.
