Mapping Barriers to Sustainable Fashion Consumption: Insights from Neutrosophic-Z Number and Delphi-DEMATEL Integration

Abstract

This study investigates the barriers to sustainable consumption within the Vietnamese fashion 
industry, a critical issue given the sector’s significant environmental impact and growing consumer awareness. 
The research employs an innovative combination of Neutrosophic Z-number sets (NZN), Delphi, and 
Decision-Making Trial and Evaluation Laboratory (DEMATEL) methodologies to systematically identify and 
analyze 47 barriers across five key dimensions: Social and Cultural Factors, Pricing and Affordability, Policy 
and Education, Perception and Image, and Supply Chain and Industry Practices. Through expert evaluations 
and causal analysis, the study reveals that Policy and Education are the most influential factors, highlighting 
the need for robust policy frameworks and educational initiatives to drive sustainable consumption. The NZN 
addresses the limitations of traditional decision-making models by capturing the uncertainty and complexity 
of consumer behaviors. The findings provide valuable insights for both academics and practitioners, offering 
theoretical contributions to sustainable consumption research and practical recommendations for businesses 
and policymakers. These include enhancing product variety and affordability, promoting sustainable practices 
through education, and improving supply chain transparency. Future research should explore longitudinal 
studies and comparative analyses across different markets to validate these findings and further refine 
approaches to fostering sustainability within the fashion industry.
