For calculating the annual expenditure on each item, we employed the Household Expenditure Survey (HES). This is a survey conducted to investigate the actual
state of household incomes and expenditures in terms of expenditure and consumption. We used the data collected in 2005 as the base year. This survey is performed
every month for 981 consumption items for 8,000 households in 168 villages, towns
and cities all over Japan by the Statistics Bureau, Ministry of Internal Affairs and
Communications. The results of the survey are announced monthly and yearly for
cities, regions, types of households (i.e. total number of households, households of
more than two, single person households). In order to estimate CO 2 emissions from
household consumption within a zone, we correlated the items of HES to 3EID. For
a detailed specification, see Table 12.1.
