Abstract
Based on ninety-five-sector input-output tables for China for 1992, 1997 and 2002, this paper calculates the direct and indirect household energy consumption and associated CO2 emissions and analyzes the impacts of different household lifestyles on China's energy use and CO2 emissions during the period 1992-2002. Results reveal that more than 55% of household energy use and 58% of associated CO2 emissions were indirect during the period. Annual energy use sustaining urban residents' lifestyle increased to 24GJ per capita and associated CO2 emissions reached 2.4t per capita and it was 19.7GJ to sustain rural residents' lifestyle and associated CO2 emissions was 1.8t per capita in 2002. Though the intensity of household energy use and associated CO2 emissions declined, the total accounts had been rising slightly due to the increasing household consumption activity, number of households and change of expenditure structure, which surpassed the improvement of energy efficiency.
