As the target for stabilizing greenhouse gas emission is set both nationally and internationally, concrete countermeasures to reduce the greenhouse gas(GHG) emission should be urgently assessed, for all sectors in the society. Especially, energy consumption from the residential and commercial(R&C) sector has been rapidly increasing for recent years. Countermeasures for this sector are really important to reduce overall emission of GHG.
The purpose of this research project is first to compile systematic inventory of the carbon dioxide(CO2) emission from the R&C sector, second to identify possible countermeasures to reduce the emission, and third to assess various countermeasures from comprehensive viewpoints including effectiveness, cost performance, safety, public acceptance and difficulties of technological innovation.
We clarified the trend and the structure of CO2 emission based on the energy balance statistics and developed the input-output analysis method to analyze them from the viewpoint of final demand. Moreover, we analyzed the CO2 emission from the R&C sector, through the consumption of non-energy commodities. On the other hand, based on a questionnaire survey, we estimated the amount of CO2 reduction by household actions to reduce the emission and analyzed factors inhibiting their actions. About half of the CO2 emission in Japan has a relation with consumption expenditures of household, it is important to take countermeasures in the sector based on energy-saving and resources-saving.
