Green supply chain management involves integrating environmental considerations into the management of materials, information and finances as products move through the supply chain. It improves operations by employing environmental solutions, increases adaptability and promotes better alignment between business processes and principles. Key areas to green the supply chain include designing eco-friendly products using less material and computational tools, implementing green purchasing policies, achieving lean and efficient production, using sustainable packaging and optimizing logistics through direct shipping and reverse logistics. Other green initiatives organizations have adopted are eco-labeling, LEED building standards and green sourcing.
