Abstract
This study aims to estimate household CO2 emissions and passenger car CO2 emissions of municipalities in Japan to compare the characteristics of cities for low carbon societies. Revised estimation methods were developed from the standard shown in the 2017 version national manual. Household CO2 emissions by municipality were estimated reflecting the difference between single-family households or two or more households and the difference between detached houses or apartment houses in 10 regiions. Passenger car CO2 emissions by municipality calculated with road traffic census were edited according to its reliability. .As a result, it was found that emissions are small in metropolitan cities with a high proportion of household living in apartment houses, and that emissions are high in suburbs of the Chugoku region in addition to the Hokkaido region and Tohoku region.
