Abstract
Since 1998, in response to national policies prescribed in Outline for Promotion Effects to Prevent Global Warming and Law Concerning the Promotion of the Measures to Cope with Global Warming at national, local governments have started to establish regional plan to combat global warming. The plan includes a report on local GHGs emissions inventory, numerical target on GHGs emissions reduction, and its sectoral action plans. This study first critically reviews the practical methods of CO2 emissions inventory in residential sector which are currently used widely based on publicly available statistical data. Then we compare the results of CO2 emissions in residential sector based on our questionnaire survey in Hiroshima Prefecture which can consider regional local conditions more in detail. Finally using detail profiles of residential sector in Hiroshima Prefecture, we try to have future projections on CO2 emission in residential sector.
