Was ist genug? Begründung, Potentiale und Empfehlungen für mehr Suffizienz(orientierung) [What is enough? Rationale, potentials, and recommendations for more sufficiency (orientation)]

Sufficiency has long been marginalized in the public and political sustainability discourse. Since attempts to reduce CO2 emissions in the long term have so far fallen short of expectations, sufficiency has recently approached the forefront of scientific and social debates about a »good life«. In addition to a strict reduction target, the sufficiency strategy promises psychological well-being and global socio-ecological justice. The aim of this text is to introduce sufficiency and sufficiency orientation as concepts and to highlight practical implications to foster a socio-ecological transformation in the spirit of sufficiency. We begin by outlining how the concept of sufficiency is to be classified in the sustainability discussion and what psychological links can arise from it. We then describe, in the form of an excursus, to what extent minimalism can be regarded as a popular counterpart to sufficiency, what limits minimalism currently reveals with regard to ecological questions, and to what extent both concepts could mutually stimulate each other through their references to subjective well-being and as societal trends against overconsumption. We then present recent research contributions on materialism, well-being, time wealth, and basic psychological needs that make obvious cross-connections to sufficiency. Finally, we present concrete approaches to promote sufficiency and sufficiency orientation that aim to advance a socio-ecological transformation through interactions with more structural levels of society.
