The call for ‘sustainable degrowth’ has recently turned into a focal point of critical social and ecological debate, as well as a framework for diverse strands of activism. So far, little is known about the motives, attitudes and practices of grassroots activists within the degrowth spectrum. This article presents results of a survey conducted at the 2014 International Degrowth Conference, revealing both the presence of a widely shared basic consensus among respondents and their broad division into five distinguishable sub-currents. A cluster analysis shows that degrowth provides a framework for a diversity of critical and transformational approaches. We identify and describe five such currents: eco-radical sufficiency-oriented critics of civilisation; moderate immanent reformers; a transitory group of voluntarist-pacifist idealists; the modernist rationalist Left; and the alternative practical Left.
