Supply-chain sustainability is the management of environmental, social and economic impacts and the encouragement of good governance practices, throughout the lifecycles of goods and services.[1] There is a growing need for integrating sustainable choices into supply-chain management. An increasing concern for sustainability is transforming how companies approach business. Whether motivated by their customers, corporate values or business opportunity, traditional priorities such as quality, efficiency and cost regularly compete for attention with concerns such as working conditions and environmental impact.[2] A sustainable supply chain seizes value chain opportunities and offers significant competitive advantages for early adopters and process innovators.[3]
