Central to debates concerned with societal transition towards low-carbon living is the imperative to encourage individual subjects to shift their behaviours to support less consumptive ways of life: eating less meat, consuming less energy and water, and wasting less of what we do consume. Exploring narratives derived from 30 interviews with householders living in and around a UK city, this article considers the dynamics surrounding consumption, unpacking the notion that consumers act as agents of choice. Drawing on accounts of daily routines, the article pays close attention to the complexity of social, cultural and material factors that shape narratives of daily life, where food emerges as a core organising principle. This suggests that food practice provides a nexus point around which change can be more effectively conceptualised for public policies aimed at inculcating more sustainable ways of life. That is, through an understanding of food practice, we can explore means of locking and unlocking wider practices deemed unsustainable.
