Many current sustainability considerations in industry constrain design space by emphasizing reduced material and energy flows across product life cycles. However, there are also opportunities for sustainability awareness to extend design space and drive innovation. Product-service systems (PSS) in particular can be a vehicle through which sustainability-driven innovation occurs. A framework for strategic sustainable development, including a backcasting approach, provides the basis for understanding sustainability in this work and provides insight into how incremental and radical approaches could be aligned within product innovation. This work explores how sustainability considerations can be better integrated into existing product innovati...
