ABSTRACT
Eco-efficient Product-Service Systems (PSS) represent a promising approach to sustainability. One key reason is that eco-efficient PSSs are often radical innovations and their adoption usually challenges existing customers' habits, companies' organisations, and regulative framework. This chapter focuses on the barriers that affect the attractiveness and acceptance of eco-efficient PSS alternatives and opened the debate on the role that aesthetics can play in stimulating users to perceive PSS alternatives as more satisfying than traditional 'product-based' offers—both during the purchase choice and during use. Aesthetical attention requires the product-service to be designed as part of a common language, a language that everyone can speak and, above all, through which each subject has the opportunity to communicate with other subjects. The use of PSS requires getting to the heart of the PSS instead. It requires not only touching, but also the possibility to adapt, to remodel, to rearticulate and to one's own liking the forms of the system.
