This article introduces the concept of sufficiency, its specific dual nature (voluntary and obligatory), and its collective implications to the literature on sustainability. Sufficiency implies a reorganization of consumption priorities and is introduced by a discussion of consumerism and the dominant social paradigm. Long interviews with sufficient people show the complexity of the construct, which creates semantic oppositions around the notion of having (everything vs. nothing and not nothing vs. not everything). After a semiotic analysis of people’s interpretation of sufficiency, we propose a reflection about the use of macromarketing tools to better enhance and enact sufficiency in a collective way.
