Although the population of Japan is going to decrease, the energy consumption of the residential sector is assumed to increase. On the other hand, new construction will decrease gradually, and the ratio of the existing houses in housing market will grow up. This research shows the prediction of CO 2 emission between 2005 and 2050 from housing sector of Fukuoka Prefecture by construction, operation, demolition and area based on the present situation of the housing stock. Fukuoka Prefecture is divided into "Fukuoka City", "Kitakyushu City" and "The other area". The trend CO2 emission and the main factor are different by areas, directly because the decrease of population and the change of household composition. Accordingly the effect of the measures would change .In Fukuoka City CO2 emission has a high percentage of the construction and operation factor on apartment house, therefore it is said that the measures for the apartment house are comparatively important. Meanwhile in Kitakyushu City and The other area, new construction of detached house has a large percentage in new construction, but taken altogether, it is a small amount. The measures for the housing stock are important.
