This keynote presents Product-Service System Design for Sustainability as a promising approach to tackle in emerging and low-income contexts the socio-ethical dimension of sustainability together with the environmental and economic ones. Firstly, reasons for applying eco-efficient Product Service Systems (PSS) innovation in low-income and emerging contexts are highlighted. Secondly, the known model of distributed economy is introduced as a promising characteristic of such eco-efficient Product-Service Systems to address the issue of locally based renewable and sustainable energy systems as the key leverage for a democratisation of access to resources, goods and services. In this framework the EU funded Learning Network on Sustainability (LeNS) project and its Method for System Design for Sustainability (MSDS) are presented
