We are all consumers. What we consume, how, and how much, has consequences of great moral importance for humans, animals, and the environment. Great challenges lie ahead as we are facing population growth and climate change and reduced availability of fossil fuels. It is often argued that key to meeting those challenges is changing consumption patterns among individual as well as institutions, for instance through reducing meat consumption, switching to organic or fair trade products, boycotting or ‘buycotting’ certain products, or consuming less overall. There is considerable disagreement regarding how to bring this about, whose responsibility it is, and even whether it is desirable. Is it a question of political initiatives, producer responsibility, the virtues and vices of individual consumers in the developed world, or something else? Many of these issues pose profound intellectual challenges at the intersection of ethics, political philosophy, economics, and several other fields. This publication brings together contributions from scholars in numerous disciplines, including philosophy, law, economics, sociology and animal welfare, who explore the theme of ‘the ethics of consumption’ from different angles.
