A guide for evaluating the environmental performance of Product/Service-Systems

Environmental issues, such as climate change, resource depletion and pollution are societal concerns, which are also increasingly affecting the way we do business.
Concepts such as circular economy,sharing economy, and service economy, often highlight that more sustainable businesses can be created when focusing on product performance (e.g.by offering lighting as a service) rather than the physical products (e.g. by selling light bulbs).
Such strategies of integrating products and services to deliver required user functionality are often termed Product/Service-Systems (PSS). This guide is intended to support studies that aim to explore ifor when a PSS is leading to environmental improvements.The guide consists of six steps,which will assist the user to evaluate the environmental performance of PSS using Life Cycle Assessment (LCA) methodology. Special attention is given to the scoping phase of the study. This section of the guide introduces PSS as a concept, explains the aim of the guide, and provides an overview of stakeholders with potential interest in the guide plusthe set of competences needed to perform the study.
