Abstract: This paper focuses on the input-output model to calculate the carbon emissions from household energy consumption in recent years in China and United States. On this basis, we calculate the two countries' residents of different income levels of carbon emissions in 2010.The results show that in recent years the carbon emissions from U.S. residents have always been higher than the emissions from Chinese. However, the growth in carbon emissions increases rapidly, the gap between two countries is also shrinking each year. Therefore, the government must advocate residents to establish a rational consumption patterns, effectively reducing consumer carbon emissions.
