The conditions of both global sustainability and prosperity of local communities must be fulfilled simultaneously in the formation of a sustainable society. To this end, application of academic knowledge in relevant fields such as chemical engineering is required, as well as cooperation among a diversity of stakeholders. In this study, we modeled the capacity of society needed for sustainability with three elements of hardware, software and humanware such as human consciousness and behavior, and examined the validity of the modeling through an analysis of a past international cooperation project. As a result, it was shown that a component to improve capacity related to humanware, which has not been always considered by designers as a project/program component, can have a significant impact on the capacity of society.
