In this timely book, Sven Rudolph and Elena Aydos take an interdisciplinary approach that combines sustainability economics, political economy, and legal concepts to answer two fundamental questions: How can carbon markets be designed to be effective, efficient and just at the same time? And how can the political barriers to sustainable carbon markets be overcome? The authors advance existing theoretical frameworks and examine empirical data from various real-life emissions trading schemes, identifying strategies and policy windows for implementing truly sustainable ETS.
