It was found that milage data from the vehicle inspection certificate data for light motor vehicles were also available. By using the annual mileage of light motor vehicles for passengers and passenger cars by municipality nationwide obtained from the vehicle inspection certihicate data, the CO2 emissions per capita of private passenger cars were estimated with higher reliability than before, and it was shown that CO2 emissions are high in eastern Hokkaido, Ibaraki and Fukushima, among other regions. It also analysed the differences in the amount of light motor vehilcles and passenger cars travelled by municipality, etc., and attempted to use this information to examine decarbonisation measures by municipality as an example of measures toward decarbonised societies. The study showed that the diffusion of electric vehicles through home recharging is considered easier in island areas and inland municipalities in western Japan, where the annual milages is short and the share of light motor vehicles for passenger is high.
