Copyright @ 2014 Greenleaf Publishing.Eco-efficient Product-Service Systems (PSS, in which the economic interest of the stakeholders involved in the offer continuously foster the optimisation of environmental resource consumption) represent a promising approach to sustainability. However, despite their potential win–win characteristics, the application of this concept is still limited. One key reason is that eco-efficient PSSs are often radical innovations and their adoption usually challenges existing customers’ habits (cultural barriers), companies’ organisations (corporate barriers), and regulative framework (regulative barriers). Starting from these considerations this chapter first investigates the barriers that affect the attractiveness and acceptance of eco-efficient PSS alternatives. A debate is then opened on the aesthetics of eco-efficient PSSs and the way in which aesthetics could enhance specific inner qualities of eco-efficient PSSs, i.e. facilitating and enhancing their wider diffusion. Through the analysis of several case studies, and integrating insights from semiotics, the chapter then outlines several research hypotheses on how the aesthetic elements of an eco-efficient PSS could facilitate user attraction, acceptance and satisfaction
