This edited volume provides both a broad overview of cooperation patterns in the UNFCCC climate change negotiations and an in-depth analysis of specific coalitions and their relations. Over the course of three parts, this book maps out and takes stock of patterns of cooperation in the climate change negotiations since their inception in 1995. In Part I, the authors focus on the evolution of coalitions over time, examining why these emerged and how they function. Part II drills deeper into a set of coalitions, particularly "new" political groups that have emerged in the last rounds of negotiations around the Copenhagen Accord and the Paris Agreement. Finally, Part III explores common themes and open questions in coalition research, and provides a comprehensive overview of coalitions in the climate change negotiations. By taking a broad approach to the study of coalitions in the climate change negotiations, this volume is an essential reference source for researchers, students, and negotiators with an interest in the dynamics of climate negotiations.
