Abstract
Many outputs of the application of eco-design principles and guidelines result in solutions that slightly differ from previous ones. Although the environmental advantages of new solutions are evident, the extent of achieved benefits fails to pursue the objectives of sustainable development. The latter requires disruptive change and the contextual demise of old generations of products with worse environmental performance. This is made possible just when environmental friendly product transformations positively capture the social and the economic dimension too, as these are accompanied by changes in people’s habits and fueled by customer satisfaction. However, few enterprises are available to engage in radical innovation, as it is generally understood as a risky endeavor. The situation is made more complicated by the relatively poor availability of design methods that target radical product redesign. Proactive design methods and thinking strategies are commonly in play when substantial design changes are expected, but no standard methodological reference has been established so far. Based on theoretical reflections and literature evidence, the paper outlines the need for new knowledge, as the foundation of new methodological frameworks to enable the design of products whose environmental, social, and economic sustainability is ensured.
