Environmental sustainability in supply chain management is about making sure that goods and services are procured in ways that do not harm the environment. This means reducing, reusing and recycling resources whenever possible, finding alternative sources of energy and better ways to use them, and promoting businesses who adhere to eco-friendly practices. It also involves working with suppliers, vendors and partners to ensure they too are committed to sustainability. To put it simply, environmental sustainability in supply chain management is about creating a sustainable future for our planet.
