Offices, retails, households and transport, such as urban activities account for around 50 % of CO2 emissions in Japan. For tackling this issue, effective energy utilization is necessary in particularly high dense area. In response to this, the Government of Japan is promoting energy centers in public spaces with energy networks. This paper deals with energy center development in public spaces and attempts to clarify how use of public spaces for energy center can secure CO2 emission reductions. We firstly review energy policies in Sapporo City and followed by an analysis of construction of energy center under several cases. From the analysis, we found that energy center under the public park is effectively worked for reduced CO2 emissions, however, initial cost and high energy prices and so on are negatively affected to the energy businesses.
