Sufficiency is about the conscious reduction of our material and energy needs – particularly those from non-renewable resources. The concept is based on an understanding of prosperity and quality of life that emphasizes values other than consumption. Together with more productive use of resources (efficiency) and use of environmentally friendly technologies (consistency), sufficiency is indispensable to bring our consumption and economic activities in line with the limits of our planet.

CDE investigates the potential benefits of sufficiency solutions for humans and ecosystems in various projects. We look for different ways of anchoring sufficiency – whether in language, individual lifestyles, education, business, work, or society.
