Comparative Environmental Regionalism focuses on environmental governance as a key issue of analysis to provide an important new conceptualisation of ''region'' and regional power.

Examining both interregionalism and regional integration, the book goes beyond the traditional study of micro-regions within the EU to examine regions and regional institutions across Asia, Africa and the Americas. The focus on forms of governance allows a consideration of the variety of processes and mechanisms developed to deal with collective issues in addition to formal institutional cooperation.

Using globally based case studies, Comparative Environmental Regionalism will be of interest to students and scholars of environmental and regional politics, and international relations.
