CO_2 emissions from households increase with improved living standards and a growing population. Analysis of assessments and predictions for household CO_2 emissions is significant to provide effective low- carbon measures for governments. This work explored the peak value of household CO_2 emissions in urban areas,rural areas and the whole China based on IPAT modeling and scenario analysis. From the perspective of peak prediction,we found that household CO_2 emissions will not achieve peak value before 2050 based on the Baseline Scenario and High-carbon Scenario both in China,urban areas and rural areas. Based on the Low-carbon Scenario,peak value time of household CO_2 emissions in China,urban areas and rural areas will be achieved in 2046, 2045 and 2046,respectively;the peak value will be 7.3 billion t CO_2,5.6 billion t CO_2 and 1.7 billion t CO_2,respectively. Based on the Enhanced Low-carbon Scenario,the peak value time of household CO_2 emissions in China,urban areas and rural areas all will be achieved in 2040;the peak value will be 6.3 billion t CO_2,4.7 billion t CO_2 and 1.6 billion t CO_2,respectively. Based on the results of the peak value of household CO_2 emissions,low- carbon suggestions,such as to encourage multi- generation members living together,to enhance peoples awareness on energy saving and to master the green development plan and low- carbon construction plan,should be provided. Only by considering the current response and mitigation policies to adapt to climate change,special policies and measures needed to be made in the household sector,the peak value of household CO_2 emissions will be achieved based on Low-carbon Scenario and Enhanced the Lowcarbon Scenario in China. The results also gave the data support for achieving 40% ~ 45% carbon reduction targets in 2020 and peak value targets around 2030.
