Institutional change for strong sustainable consumption: sustainable consumption and the degrowth economy

Abstract

The environmental space concept illustrates that socially unsustainable underconsumption must be overcome and environmentally unsustainable overconsumption must be phased out. The planetary boundaries help to quantify the "ceiling, " while the social protection floor concept operationalizes the linea de dignidad, the minimal conditions for a dignified life. In order for Western societies to respect these limits, significant institutional change is needed with respect to both orientations and mechanisms. For the ceiling, this article suggests a shift to an orientation of "better but less" for affluent groups, and toward "enough and better" for those still living in poverty. The corresponding mechanisms include a redistribution of income and wealth, a cap on income, an unconditional minimum income, and a strengthening of democracy. The choice of instruments has to take into account that consumption is to a large degree not an individual but a social act and to employ informational, financial, and legal measures that overcome the preference of decision makers for market instruments. Implementing these changes would alter the fabric of our societies. Important first steps can be taken here and now. © 2014 Spangenberg.
