Sustainable Consumption Communities (SuCoCom) can make an important contribution to the transformation toward greater environmental and social sustainability of the economy and society. However, such communities usually have a niche existence. In order to emerge from this niche and to integrate as many consumers as possible into such communities, there must be a corresponding level of acceptance among the population. This is the starting point for this article, which examines acceptance barriers and obstacles to the (active) participation of private individuals in SuCoComs on the basis of an empirical study of over 900 test persons in Germany.
