This fine and important report, by Andrew Pendleton and Simon Retallack of the British Institute for Public Policy Research, was funded by the Heinrich Boell Foundation in Germany. It is unusually useful, particularly in its concise and focused approach to the key question of … well … fairness in global climate finance. It comes highly recommended, and not just because it speaks so very well of the GDRs approach. Rather, it goes beyond the basic GDRs analysis to explore a number of possible approaches to using the Responsibility and Capacity index. In practice!
