Interdisciplinary and comprehensive, the Research Handbook on Transnational Environmental Law (Edward Elgar, 2020), edited by Professor Veerle Heyvaert and Dr Leslie-Anne Duvic-Paoli, provides stimulating and provocative discussions on transnational legal phenomena and the ways in which we can unpack their complexities. Bringing together varied perspectives from both leading and emerging scholars from around the world, chapters deliver methodological and conceptual frameworks for future research, whilst providing an original view on this emerging field of law. Contributors also pay special attention to the engagement of environmental law with multilevel governance and the involvement of non-state actors in legislative, regulatory and adjudicative processes.
