ABSTRACT
Transition towards sustainability requires radical changes in the way we produce and consume and, in general, in the way we live. The prospect of sustainability necessarily places the very model of development under discussion. In future decades we must be able to move from a society in which well-being and affluence are measured by the production and consumption of goods to one in which people live better, consuming (much) less. In fact, we need to learn how to live better (the entire population of the planet: the equity principle) and, at the same time, reduce our ecological footprint.
