It is analysed that the urban disaster with pandemic and its related consequences are associated with the global warming induced by the carbon-emitted fossil fuels. In 'urban disaster', the result is shown as a stepwise form in which the effectiveness of urban disaster increases. In addition, 'energy-mix' and 'energy' decrease in their effectiveness, although 'traffic, communication, etc.', 'health, quarantine, etc.', and 'resilience' increase in their effectiveness. This means that three variables, 'traffic, communication, etc.', 'health, quarantine, etc.', and 'resilience', affect the 'energy-mix' and 'energy' as the feedback algorithm. It is analysed for urban disasters with ecological pandemic situations where the social distancing is very important in the urban places due to the higher population density than the rural areas. In this work, the prospects of pandemic society incorporated with the climate change mitigating by energy-mix policy are investigated.
