Book excerpt: This book brings together leading and emerging scholars and practitioners to present an overview of how regional, international and transnational courts and tribunals are engaging with the environment. With the natural world under unprecedented pressure, the book highlights the challenges and opportunities presented by international dispute resolution for the protection of the environment and the further development of international environmental law. Presented in three parts, it addresses how individual courts and tribunals engage with environmental matters (Part I); how courts and tribunals are resolving key issues common to environmental litigation (Part II); and future opportunities and developments in the field (Part III). The book is an essential one-stop-shop for students, practitioners and academics alike interested in international litigation and the protection of our global environment. Edgardo Sobenes is an international lawyer and consultant in international law (ESILA), Sarah Mead is a lawyer specialising in international environmental and human rights law, and Benjamin Samson is a researcher at the Université Paris Nanterre and consultant in international law.
