Assessing the Impact of Sustainable Procurement on Supply Chain Performance: A Case Study of Logistics Companies in Salalah, Oman

Abstract

This study investigates the impact of sustainable procurement practices on supply chain performance in the logistics sector of Salalah, Oman. As sustainability becomes increasingly vital to global supply chain strategies, emerging economies face distinct challenges and opportunities in integrating environmentally and socially responsible practices. The research explores how sustainable procurement influences operational efficiency, risk resilience, and financial outcomes within logistics firms, while also identifying the barriers to effective implementation.

A mixed-method approach was employed, incorporating quantitative survey data from 136 logistics professionals and thematic analysis of relevant academic literature. Statistical techniques including descriptive statistics, correlation, regression, mediation, and moderation analyses were used to assess the relationships among the variables. The findings revealed a strong positive relationship between sustainable procurement and both operational efficiency and risk mitigation. Cost reduction was found to partially mediate this relationship, highlighting its role as a key mechanism through which sustainability delivers value. Additionally, external barriers such as regulatory constraints and supplier limitations were found to moderate the overall impact on supply chain performance. The results affirm the strategic value of sustainable procurement and offer actionable insights for practitioners and policymakers aiming to enhance logistics performance through sustainability. The study concludes by recommending greater institutional support, improved supplier engagement, and investment in training and technology to overcome implementation challenges.
