In May of 2007, an Oxfam International report, Adapting to climate change: What’s needed in poor countries, and who should pay?, marked a major step in the evolution and diffusion of the GDRs approach. Not that Oxfam’s “Adaptation Financing Index” is exactly the same as our “Responsibility and Capacity Index.” For one thing, we apply the RCI to mitigation as well as adaptation obligations. But the two systems share both a common DNA and a common vision, and they point in the same direction.
