The artec members Sigrid Kannengießer and InesWeller have published the edited volume. An interdisciplinary team has studied consumption-critical projects and practices by analyzing the following key questions:
Which actors organize and participate in such projects? What is the aim of the involved parties? What kind of social significance do they ascribe to their projects? Are there changes in the practice of critical consumption that can be identified? In which way does the involvement in consumption-critical projects influence own consumption patterns?
