More than 1,000 local governments have committed to achieving zero carbon cities by 2050 in Japan. Each region needs to draw up future scenarios and develop a strategic plan to realize combined value including decarbonization. Based on this recognition, we share the contents of our efforts for the “Development of Regional Planning System of Green Innovation for a Decarbonized Society and Establishment of Social Implementation Network through Regional Coalition Action”. Toward regional decarbonization, it will be necessary to diagnose the current state of the region, plan alternative future goals, and design the projects necessary to achieve them. We are building a “support system for regional decarbonization planning” based on a model that sets future goals related to regional energy, next-generation transportation, construction stock management, and others being studied by each working group of the project, using climate change impacts, regional socioeconomic characteristics, and national plans as input variables and integrally estimating and outputting socioeconomic and environmental effects for the development of regional scenarios and plans. We share our efforts and status, and discuss how research can support the realization of decarbonized regions.
