What was once a purely cost-driven function is now a strategic lever for environmental responsibility, operational efficiency, and long-term resilience.

This shift has placed Sustainable Supply Chain / Green Logistics at the center of modern supply chain strategy. Sustainability is no longer limited to reducing emissions for compliance purposes; it is about redesigning logistics networks, supplier relationships, fulfillment models, and performance measurement systems to create value while minimizing environmental impact.

This article explores the principles, technologies, and practices behind Sustainable Supply Chain / Green Logistics, showing how organizations can reduce waste, improve efficiency, and build responsible supply chains without sacrificing performance.

What Is a Sustainable Supply Chain / Green Logistics?

A Sustainable Supply Chain / Green Logistics approach focuses on minimizing environmental impact while maintaining or improving operational performance. It integrates environmental, social, and governance (ESG) considerations into every stage of the supply chain—from sourcing and production to transportation, warehousing, and last-mile delivery.

Key objectives include:

• Reducing carbon emissions and fuel consumption

• Optimizing transportation and logistics networks

• Minimizing waste and excess inventory

• Improving energy efficiency across operations

• Strengthening supplier responsibility and transparency

• Ensuring long-term supply chain resilience

Unlike traditional supply chain models, sustainable supply chains balance cost, service, and environmental impact simultaneously.
