In this study, we conducted a scenario-selective Planungszelle on decarbonization measures for detached houses for the citizens of Kitakyushu, Japan. We quantitatively evaluated the participants' scenario selection process through information provision and discussion based on the questionnaire survey data conducted during the discussion and the conversation data during the discussion. The results showed that the participants as a whole selected scenarios based on the cost performance of the countermeasure equipment before the discussion. In contrast, they selected scenarios based on the social burden in the discussion after providing information on the social burden of subsidies for introducing the equipment. The "proactive group" and the "negative group" selected scenarios mainly based on cost performance. However, the difference was that the former group emphasized reducing social burden, and the latter emphasized cost reduction. The "global warming skeptics" and "global warming indifferent" chose scenarios that maintained the status quo after the discussion due to concerns about the maturity and reliability of decarbonization technologies presented in this study.
