International environmental agreements have increased exponentially within the last five decades. However, decisions on policies to address key issues such as biodiversity loss, climate change, ozone depletion, hazardous waste transport and numerous other planetary challenges require individual countries to adhere to international norms. What have been the successes and failures in the environmental treaty-making arena? How has the role of civil society and scientific consensus contributed to this maturing process? Why have some treaties been more enforceable than others and which theories of international relations can further inform efforts in this regard? Addressing these questions with renewed emphasis on close case analysis makes this volume a timely and thorough postscript to the Rio-Plus 20 summit’s celebrated invocation document, The Future We Want, towards sustainable development. Environmental Diplomacy: Negotiating More Effective Global Agreements provides an accessible narrative on understanding the geopolitics of negotiating international environmental agreements and clear guidance on improving the current system. In this book, authors Lawrence Susskind and Saleem Ali expertly observe international environmental negotiations to effectively inform the reader on the geopolitics of protecting our planet. This second edition offers an additional perspective from the Global South as well as providing a broader analysis of the role of science in environmental treaty-making. It provides a unique contribution as a panoramic analysis of the process of environmental treaty-making.
