In the last decades, citizens increasingly used political consumerism and lifestyle activism to contribute to social change in western democracies. Political consumerism is a form of participation related to citizens purchasing choices and lifestyle activism as choices in everyday life shaped by political values. Research shows that buying organic food, exchanging clothes, or cycling to work are part of contemporary action repertoires. These forms of political participationdefine what it means to be a citizens. Yet, few studies question the underpinning understandings of social change and democratic decision-making processes at the core of these two forms of political participation. In this chapter, we ask: what are the mechanism and procedural understandings of social change associated with political consumerism and lifestyle activism. We examine processes associated with the transformation of society through political consumerism and lifestyle activism. We first discuss how these forms of participation contribute to contemporary action repertoires. Then,we analyze the mechanisms associated with social changes that result from these forms of political participation and their conceptions of collective decision-making processes.We argue that political consumerism and lifestyle activism are associated with unequal political participationand that they lack a procedural understanding of democracy that allows the inclusion ofdifferent segments of society in decision-making processes.
