In order to promote transition from the current system into a sustainable one, it is essential to plan and implement various measures and options among socio-economic system and technological system with the cooperation of stakeholders. An integrated assessment model (IAM) is one of the methods to evaluate measures of technologies and policies toward the sustainable society while ensuring the consistency of various elements in the society. The case study of application for regional climate change mitigation showed that, technical measures such as the introduction of high-efficiency appliances, as well as changes in land use pattern and urban structure and installation of local energy system utilizing local energy resources are important for reduction of CO2 emissions. IAM requires a various type of data among socio-economic situation, energy system, material stock and local resources for evaluation of technological and policy measures and options; however, such data-related limitations can be overcome by referring to the research outcomes for understanding the current situation of region, as well as precedent cases of regions with similar characteristics to the target region. The IAM expects to lead to plan future pathways to sustainable society that is consistent with each other’s efforts and utilizing local resources.
