The Four Gaps of Sustainable Fashion

Sustainable fashion requires bridging four gaps: Psychological (values-behavior), Technological (lab-field effectiveness), Ethical (design-implementation), and Inclusion (equitable access). This chapter integrates behavioral insights, AI nudging, gamification, and ethical governance. Behavioral interventions increase sustainable choices 25-45% but experience habituation; AI gains (28%) are offset by rebound effects; blockchain concentrates benefits among large firms. The Conceptual Gap Model explains why isolated interventions fail: addressing one gap may widen others without simultaneous action. Transformation demands coordinated psychological, technological, ethical, and systemic approaches. Some gaps require structural business model innovation beyond technology. This perspective reframes sustainable fashion from individual behavior change toward ecosystem coordination, requiring simultaneous attention to authenticity, equity, governance, and transformation.
