Sustainable Consumption Communities (SuCoCom) can make an important contribution to the transformation towards greater ecological and social sustainability of the economy and society.

This is where the article comes in, which examines the acceptance determinants and barriers to (active) participation of private individuals in SuCoComs on the basis of an empirical study of over 900 respondents in Germany.
