From the viewpoint of global-warming prevention, it is asked for the curtailment of the amount of CO2 discharge in the advanced countries including Japan internationally. In Kyoto COP3 (The 3rd Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) in 1997, Japan is lifting the target value which will cut down the amount of CO2 discharge 6% in 2010 compared with 1990. In this study, a planning and evaluation system for introducing distributed generators in city level was built using GIS. An arrangement planning of the distributed generators in the Tokyo's 23 wards was performed using the planning and evaluation system. Curtailment of commercial and residential sector's energy and CO2 discharge was calculated from the field of energy-saving nature, environmental-preservation nature, and enterprise nature. The result showed that when the unused energy and CGS were introduced in 500m mesh, the rate of injection primary energy curtailment and CO2 curtailment became 11.4% and 15.3% in the Tokyo's 23 wards. The amount of CO2 curtailment became the result equivalent to 76% of the amount of required curtailment of Tokyo.
