Book excerpt: The Law and Politics of Sustainability explores efforts made to address pressing environmental concerns through legislation, conventions, directives, treaties, and protocols. Articles explain the mechanics of environmental law, the concepts that shape sustainable development, case studies and rulings that have set precedents, approaches to sustainable development taken by legal systems around the world, and more. Experts and scholars in the field raise provocative questions about the effectiveness of international law versus national law in protecting the environment, and about the effect of current laws on future generations. They analyze the successes and shortcomings of present legal instruments, corporate and public policies, social movements, and conceptual strategies, offering readers a preview of the steps necessary to develop laws and policies that will promote genuine sustainability.
