A keynote delivered at the conference Climate Law in Developing Countries post-2012: North and South Perspectives, organized by the IUCN Academy of Environmental Law, September 26-28, 2008. Faculty of Law, University of Ottawa. This is a really excellent speech. It not only endorses GDRs, it also puts it nicely into its proper context.
