      <abstract>
        <p>Welcome to the 1st International Workshop on Cyber-Physical Social Systems for Sustainability (CPSS4Sus). The workshop is a forum for researchers and practitioners to discuss the challenges and opportunities brought by Cyber-Physical System (CPSS) to promote strong and fair communities. In particular, we are interested in how issues, such as social and health equity, community development, human rights and social justice can be integrated into the early development of CPS. We received 3 submissions and all submissions were reviewed by at least four members of the Program Committee. During our workshop, we discussed two very interesting proposals. Ramalu and Törngren presented the paper Towards an Architectural Framework and Trustworthy Complex Cyber-Physical Systems. The paper outlines a framework to facilitate the considerations of trustworthiness in CPS systems, exemplifying its application in two intelligent transportation systems use cases. Corte-Cornax, Lago and Roncancio presented the short paper Cyber cycle analysis of physical devices and data can help CPS designers to converge into an equilibrium of utility, performance and minimal environmental impact.</p>
