The book covers all major environmental agreements, paying particular attention to their underlying structure, main legal provisions and practical operation. It blends legal and policy analysis, making extensive reference to the jurisprudence and scholarship, and addressing the interconnections with other areas of international law, including human rights, humanitarian law, trade and foreign investment. The material is structured into four sections - foundations, substantive regulation, implementation, and influence on other areas of international law - which help the reader to navigate the different areas of international environmental law. Each chapter includes charts summarising the main components of the relevant legal frameworks and provides a detailed bibliography. Suitable for practising and academic international lawyers who want an accessible, up-to-date introduction to contemporary international environmental law, as well as non-lawyers seeking a concise and clear understanding of the subject.
