In recent planning and policy making, utopian thought and experimental approaches to the organization of society and the built environment have been rare. Sustainable society is viewed as something created within the framework of current society, by small steps. This book analyzes the potential of alternative green futures through perspectives such as political ecology, environmental justice, and utopian thought. It includes analyses of strategies and emerging practices on the macro levels of institutional, infrastructural and economic change, and also analyzes micropractices in the form of case studies of self-organised cooperative housing, new forms of local exchange and energy provision.
