This document discusses system design for sustainability, with a focus on social equity and cohesion. It addresses how product-service systems (PSS) can provide sustainable opportunities for low and middle-income contexts. Distributed economies, which involve small, locally-based and networked production units, show promise as a PSS approach that can enhance socio-economic development and reduce inequality in these contexts. The document provides examples of PSS cases and outlines how distributed economies may facilitate social equity and cohesion through greater participation and more democratic access to resources.
