Effects of district heating and cooling system(DHC) introduced into 23 wards of Tokyo as of 2010 are discussed in terms of reduction of anthropogenic heat, CO2 and NOx emission which have degraded urban and global environment. The DHC in this paper utilizes thermal energy of urban river and sewer water using water heat pump technology. Based on the estimation of the thermal energy available, energy demand, districts where DHC may be introduced, we evaluate reduction of energy consumption, exhaust heat, CO2 and NOx release. It is found that the areas with DHC the annual energy consumption can be decreased by 29 0x1.e429p-891nthropogenic heat released by 13%, CO2 and NOx emission by 40 0x0p+0nd 43%, while the reduction effects are limited because many high energy consumption districts do not allow the DHC due to the lack of water resources.
