Bolstered brands use biophilic design principles to improve brand perception and engagement because of the ever-increasing consumer demand for sustainable and ecologically friendly products. Consumer brand attachment to nature and the relationship between such a link with the theory of 'Biophilia' (as defined by Wilson, 1984 as a human affinity for nature) has not been examined. In the study of branding for sustainability, the relationship between biophilia, eco–brand perception, and brand attachment is considered herein. The results indicate that biophilic design increases consumer perception of eco-friendly brands but does not have an effect on predicting brand attachment. Eco-brand perception, however, has a minor role in determining its influence on consumer-brand relationships but is not statistically significant. As reflected in the literature review, brand attachment is a complex process that is based on trust, authenticity, emotional storytelling as well as ethical consumerism. Through case studies of the successful integration of biophilic branding and sustainability narratives in Patagonia, Aesopus, and Lush, I show how brands develop stronger relationships with consumers. Based on this, the study ends with the argument that biophilic branding should be accompanied by transparent sustainability practices and emotional storytelling to boost long-term brand attachment. Further research should further investigate the potential variation of the cultural, sensory experience, and authenticity in biophilic branding.
