The proposed research will produce a step-change in behavioural and sustainability science by undertaking a mixed-method, cross-cultural study of pro-environmental behavioural spillover in order to open up new ways of promoting sustainable lifestyle change and significantly broadening our understanding of behaviour within both individuals and cultures.

There are three objectives for the research:

1. To examine ways in which environmentally-friendly behaviour, lifestyles and spillover are understood and develop within different cultures;
2. To understand drivers of behavioural consistency and (positive and negative) spillover effects across contexts, including home and work, roles, and cultures; and
3. To develop a theoretical framework for behavioural spillover and test interventions to promote spillover across different contexts and cultures.
