Life-cycle thinking is a fundamental concept underpinning the work of the LEAP Partnership. This approach takes into account all of the inputs and outputs across life-cycle states. Unlike supply chain management, life cycle management is broader in scope. Besides the typical supply chain stages, a product life cycle also includes distribution, consumption, and waste management. Life-cycle thinking seeks to provide a holistic and integrated perspective to assess both benefits and burdens from all parts of a product life cycle.
