The environmental crisis is reshaping how people consume, yet a persistent gap exists between consumers' stated sustainability values and actual behaviour. Marketing research must move beyond measuring intentions to understanding how sustainability is enacted in real-world contexts, where affordability, convenience and competing priorities constrain behavioural change.
This special issue seeks research examining the intersection of sustainability theory and practice, particularly studies exploring lived experiences of sustainable consumption and marketing's role in enabling meaningful behavioural change. The issue welcomes conceptual, qualitative, quantitative, experimental and mixed-methods contributions that connect rigorous theoretical development with real-world sustainability challenges and generate actionable implications for businesses, policymakers and communities.
