Habitual behaviors or patterns of practice? Explaining and changing repetitive climate-relevant actions

Understanding human behavior lies at the heart of responses to climate change. Many environmentally relevant behavior patterns are frequent, stable, and persistent. There is an increasing focus on understanding these patterns less in terms of deliberative processes and more in terms of habits and routines embedded in everyday life. Examinations of the 'habitual' nature of environmentally consequential activities have been approached from two theoretically distinct perspectives. From a social psychological perspective, 'habit' is studied as an intra-individual psychological construct that sustains ingrained behavior patterns in stable settings and obstructs adoption of more environmentally friendly alternatives. Sociologists from the social practice tradition, in contrast, have sought to highlight the ways in which resource-intensive 'habitual practices' become established and maintained in society through a commingling of material, procedural, and socio-discursive elements. We reflect critically upon key theoretical differences underpinning these two approaches to repetitive behaviors and review empirical work from both traditions that speaks to the relevance of 'habitual behavior patterns' central to addressing climate change. Finally, we examine how changes in habits are theorized and operationalized within both social psychological and social practice approaches, and practical implications for promoting environmentally sustainable societies.
