Eco-sufficiency

Reduction in energy and resources consumption

Ecological sufficiency, or simply sufficiency, refers to the concept or strategy to reduce the environmental footprint of societies through moderating the need for energy, carbon and material-based services and products. The term was popularised by authors such as Thomas Princen, a professor at MIT, in his 2005 book The Logic of Sufficiency. As a goal, sufficiency is about ensuring that all humans can live a good life within planetary boundaries, meaning without overshooting the ecological limits of the Earth and thus limiting resource use and pollution. Princen argues that "seeking enough when more is possible is both intuitive and rational – personally, organizationally and ecologically. And under global ecological constraint, it is ethical."
