Based on environmental input-output analysis, the authors try to identify the impetus of Chinese household consumption of carbon emissions in structural path analysis (SPA). The results indicate that, in 2012, most of the carbon emissions of Chinese household are indirect emissions, mainly from power, services, agriculture, food, wholesale and retail, transportation, postal. Carbons emissions from fertilizer and pesticide production in chemistry contribute a lot to the agricultural sector, therefore agricultural policies should properly limit the use of those chemical productions to reduce the emission. In addition, the difference of the income and consumption structure between urban and rural residents is the key factors which lead to the gap between of their carbon emission.
