Academic interests in the product-service system have shifted from the area of environmental sustainability to the socio-economic issues. In this context, life cycle assessment is no longer the only approach to interpreting the performances of product-service systems. Multiple criteria reflecting product-service quality, customer satisfaction, and the full sustainability concerns would be needed to evaluate the system solutions. In this paper, a concept of sustainable product-service efficiency is proposed to explore the relationship between product-service value and the sustainability impact. Additionally, the authors discuss how this concept can be applied to assess sustainable product-service systems.
