This ground-breaking volume provides analyses from experts around the globe on the part played by national and international law, through legislation and the courts, in advancing efforts to tackle climate change, and what needs to be done in the future. Published under the auspices of the British Institute of International and Comparative Law (BIICL), the volume builds on an event convened at BIICL, which brought together academics, legal practitioners and NGO representatives. The volume offers not only the insights from that event, but also additional materials, sollicited to offer the reader a more complete picture of how climate change litigation is evolving in a global perspective, highlighting both opportunities, and constraints. The contributions span a wide range of national jurisdictions with examples from both the Global South and the Global North. In addition, the potentialities and limitations for climate change-related cases at the regional and international levels are addressed, ranging from regional human rights courts and United Nations Treaty Bodies to the International Court of Justice, the World Trade Organization, the International Criminal Court and international arbitration. The volume will be of interest to legal scholars and legal practitioners, policy makers as well as activists and all those who are seeking to achieve change for the better in this field.
