Abstract: Household final requirement has become one of main resources of carbon emissions. This paper establishes hybrid-units input-output model by introducing energy consumption physical data. Based on this model, direct and indirect carbon emissions of urban and rural residents are calculated. The results show that indirect carbon emissions account for more than 70% of the total carbon emissions and keep increasing. To analyze and understand change of household carbon emissions in China, this paper undertakes a structural decomposition analysis of the historical change in indirect household carbon emissions from 1992 to 2007. The increase in indirect carbon emissions has been decomposed into four factors: gross requirement, urban-rural proportion of consumption, consumption structure and energy consumption coefficient which captures advances in technology. Increasing gross requirement is the first important factor for the growth in indirect carbon emissions. Technology advancement is the second important factor which contributes to the decline in indirect carbon emissions.
