'In the most convincing way, this book provides a systematic and comprehensive assessment of the state of international environmental law with regard to the principle of prevention through the analysis of its historical, present, and potential evolutions. The result provides an indispensable tool for practitioners as well as scholars.' Pierre-Marie Dupuy, Emeritus Professor, University of Paris II, Pantheon-Assas, and The Graduate Institute, Geneva 'A rich and illuminating study of the principle of prevention, which is the building block of international environmental law and the least analyzed of all environmental principles. This work fills the gap and provides readers with an excellent, in-depth analysis of all its aspects, including its historical evolution.' Malgosia Fitzmaurice, Queen Mary University of London 'Leslie-Anne Duvic-Paoli's comprehensive monograph on the prevention principle makes a major, much needed and convincing contribution to international environmental law, and judiciously contrasts the prevention and curative approaches in international law.' Eibe Riedel, Emeritus Chair of German and Comparative Public Law and European and International Law, University of Mannheim, Germany, and former member of the UN Committee on Economic, Social and Cultural Rights 'Leslie-Anne Duvic-Paoli's thoroughly researched and carefully reasoned exposition of the importance of the prevention principle as a guiding force in international environmental law is as timely as it is convincing.'
