Summary: |
The principle of common but differentiated responsibilities (CBDR) is the emanation of equity in international environmental law. It reflects the division of the world between the global South and the global North, which has been a structuring element of environmental regimes. This chapter explores the concept of differential treatment in international environmental law, its evolution and its implementation in environmental regimes. It then focuses specifically on CBDR and its recognition in environmental treaties. The next section discusses specifically CBDR in the climate change regime where it has been particularly important and controversial, and carries on by examining the continuing relevance of CBDR in the 2020s and the need for rethinking the ways in which it is implemented.
