Research On The Characteristics And Influence Factors Of Household Carbon Emissions In Beijing

Carbon emission has caused the global climate warming. China, as one of the largest carbon emission countries, has faced an increasing carbon emission pressure. In order to achieve the goal of carbon emission reduction, China is also actively looking for effective measures. Through the research, the paper find household carbon emission has become the largest emission department. So, the paper takes Beijing as the example, try to find an effective measures to carbon reduction. First, to analysis the characters of carbon emissions change. Second, to discuss the possible factors of the household’s carbon emission changing. Third, to calculate the contribute degree of different factors by construct the decomposition model. Then we give the main conclusions as follows:(1) The total amount of carbon emissions of households in Beijing is increasing year by year. The direct household carbon emission of 2010 is 2.5 times as more as that of 2000, it has increased 1913.43 million tons of carbon, and the ratio of total carbon emission has rose from 15% to 19%, and now its range first in amount China. So we can see that the household carbon emission has become the important growth point of carbon emission.(2) The household carbon emission in Beijing shows three characters: First, the households’ indirect carbon emission is larger than direct carbon emission, and the same to their growth rate. The gap between households’ indirect and direct carbon emission has increased from 1534.93 million tons of carbon in 2000 to 2338.77 million tons of carbon in 2010. So, the gap is widening. Second, the total carbon emission of urban family is significantly higher than that of rural household carbon emission, and also to same to their growth rate. The gap between urban households’ carbon emission and rural households’ carbon emission has increased from 2416.51 million tons of carbon in 2000 to 5782.21 million tons of carbon in 2010. Third, urban household indirect carbon emission is larger than its direct carbon emission; rural household direct carbon emission is larger than its indirect carbon emission.(3) The influence factors of household carbon emissions is relatively diverse, such as family size and structure, household income and consumption, energy consumption and structure, industry structure and technical progress. In order to clarify the contribution of different factors, the paper construct a model to analysis, and the results shows that: the level of per capita consumption of family contribute significantly to the direct carbon emission, the contribution degree is 135.24%; the total amount of the per capita consumption of family contribute meaningfully to the indirect carbon emission, the contribution degree is 336.35%; and the family size is the most important influence factor to urban and rural household carbon emission, for example, in 2010, its contribution degree are 143.51% and 51.07%.
