Sufficiency asks for the right measure. Sustainability will be achieved only through a threefold strategy. Eco-efficiency, enhancing the resource productivity, is broadly accepted. Consistency marks the transition to technologies consistent with nature. Both, as indispensable as they are, will miss the goal of sustainability if sufficiency is neglected. 

It refers to lifestyles and business conduct bringing to an end the overuse of goods and thereby of resources and energy.

The leading questions of an eco-sufficiency-research are:

  • Which personal attitudes or social and political conditions stand in the way of an orientation towards sufficiency, and how can these obstacles be overcome? 
  • Which insights and behaviours of individuals, groups and institutions can help to convince the broad strata of society to use resources less or differently? How can the prevailing concept of prosperity with its strong link to material goods be changed so that sustainable development can take root in society? 
  • How would lifestyles and business styles predicated on sufficiency affect the structure and growth of the economy?
  • What business models are there for corporations whose products and services contribute to a reduction in consumption?
  • Which strategies and instruments are qualified to create the necessary policy conditions to foster a sufficient lifestyle and economy instead of hindering it or disabling it even?
