The Interplay of Consumer Religiosity, Spirituality and Minimalism in Shaping Sustainable Consumption Intentions

This study aims to understand how consumer religiosity, spirituality and minimalism collectively shape sustainable consumption intentions. It is grounded in Belief Congruence Theory, which posits that aligned personal values lead to congruent behaviors. Drawing on an integrative review of existing literature, the research develops a conceptual model that considers religious and spiritual beliefs, along with minimalist values, as key internal drivers influencing individuals’ sustainable consumption choices. This study provides a conceptual framework that synthesizes insights from existing literature to identify connections between core personal values, highlighting how these internal factors collectively influence sustainable consumption intentions. The methodology involves a systematic review and conceptual integration, merging insights from environmental psychology, consumer behavior and values research. Preliminary conceptual findings suggest that when individuals hold strong religious and spiritual values - such as purpose, interconnectedness and a sense of stewardship - these values reinforce minimalist principles that favor reduced consumption and environmental care. In turn, embracing minimalism as a personal value, rather than a mere lifestyle choice, appears to strengthen the intention to engage in sustainable consumption practices. By highlighting these internal mechanisms, the study provides a theoretical foundation for future empirical research and offers practical implications for encouraging responsible consumer behavior.
