Sustainability Practices in Retail Supply Chains: A Comparative Analysis of Global Brands

This study examines sustainability practices in retail supply chains across major global brands, analyzing how sustainability initiatives are implemented, measured, and communicated. Through comparative analysis of ten leading global retailers, we investigate the depth and breadth of sustainability integration throughout their supply chains. Data from corporate sustainability reports, third-party assessments, and industry benchmarks were analyzed to determine patterns of adoption, implementation challenges, and competitive advantages. Findings reveal significant variation in approach and commitment levels, with European retailers generally demonstrating more mature sustainability frameworks than their North American and Asian counterparts. The research identifies four key dimensions of supply chain sustainability implementation: supplier engagement, materials sourcing, logistics optimization, and transparency mechanisms. Results indicate that while sustainability reporting has become standard practice, substantial gaps exist between public commitments and operational implementation. A sustainability maturity model is proposed to help retailers progress from compliance-focused approaches toward transformative business models that create shared value across the supply chain. The study contributes to understanding how sustainability practices are evolving in global retail and identifies best practices that can be adopted by retailers seeking to enhance their environmental and social performance.
