Hundreds of new bilateral, regional, and global treaties have been negotiated in relation to the world''s most pressing sustainability, development, and justice challenges over the past two decades. The majority of these face significant implementation challenges. At the same time, disputes over human rights, environmental protection, and economic development are increasingly common.Sustainable Development Law analyses these advances and challenges in the international law on sustainable development at the intersection between international social, environmental, and economic law. It opens by examining the origins of the concept of sustainable development, identifying and discussing the foundations of its legal aspects. The principles of international law related to sustainable development are considered, based on international instruments and disputes across international courts and tribunals. Later chapters provide illustrative examples of legal instruments and regimes that address the 169 targets in relation to the 17 Global Sustainable Development Goals. Finally, the authors propose cutting-edge research agendas and conclude by exploring the limits of sustainable development.Sustainable Development Law is designed as a high-level textbook, examining the nature of law of sustainable development. Chapters offer key takeaways and questions to consider for those studying the subject. It also would be suitable for practising lawyers and policy makers who want to develop their understanding of the subject area.
