The main aim of this paper is to assess and analyse how sustainable public transit (SPT) services contribute to building living cities in emerging economies through value network and resource integration/value co-creation, which is embedded on societal and environmental perspectives. The main theoretical and empirical challenges are how to understand public transport as dynamic and transformative values based service eco-system for living city regions to develop and implement a feasible and proactive tool for changing the mind-set, which is embedded on societal and environmental perspectives. The objective is to look deeper on how these emergent and fast growing cities are put together STP for building cities for people by focusing on societal and environmental issues, which value network of SPT are integrated and value is co-created within the service system. The paper has an explorative nature. It is built around three concepts - (i) SPT and value network (ii), resilient living cities in emerging economies and (iii) Societal and environmental perspectives. The paper illustrates these concepts with four different cases from Cape Town - South Africa, Buenos Aires - Argentina; Singapore - Singapore, and Jakarta - Indonesia. The study has identified the challenges of transforming emergent and fast urbanized cities, and understanding the role of public transport services from the cities perspective in an international context by embedding social and environmental perspectives. The challenges of transforming today's cities have created many new opportunities for prosperity through new ways of living and working in urban areas. The paper makes a contribution to the study of public transit services by explicitly linking the adoption of SPT value network in emerging economies based on sustainability, and resource integration/value co-creation for building resilient living cities.
