Political consumerism was developed during the 19th century and expanded at the turn of the century through social movements aimed at empowering civil society in the market. Many of these movements succeeded in building power on the consumption side. Today, we still witness several forms of political consumerism. This contribution explores the possibilities and limits of consumer involvement in sustainable consumption. The main finding of this study of the political organization of consumers is that the market may not be the only arena for changing consumer behavior. Instead, social constraint and political empowerment seem to be rather more efficient.
