This is the second special issue of the Carbon and Climate Law Review containing papers presented at a conference on “Climate Change Governance after Copenhagen”, held in Hong Kong in November 2010. The conference was jointly organized by the Law Faculties of the University of Hong Kong and University College London. In the first of our special issues, the papers examined the emergence of new sites of climate change governance at different levels of governance and in different forums. In this second special issue, the papers explore different elements of the emerging climate change “regime complex”, 1 focussing upon developments taking place in global governance and private governance.
