An Analysis Of Household Carbon Emissions And The Influencing Factors In The Capital City Of Northwest China

Household carbon emissions represent high proportion in total carbon emissions, the research of household carbon emissions contributes to carbon emission reduction from the view of family. This paper used the survey data of capital city in northwest china, Lanzhou, Urumqi, Yinchuan, Xi’an, Xining, analyzes the urban household carbon emissions and influencing factors.This article has done the following work:(1)Household carbon emissions, include direct carbon emissions and indirect carbon emissions.The indirect carbon emissions, include indirect energy (power) of carbon emissions and household consumption expenditure carbon emissions. I used the input-output table to estimate the indirect carbon emissions coefficient, then assesses the household carbon emissions, carbon emissions per capita, household carbon emissions of the same family size and household carbon emissions intensity. The household carbon emissions and per capita carbon emissions are low, account for6.98tCO2、2.21tCO2respectively, the household carbon emissions intensity are high in the urban areas, up to1.71tCO2per10thousand yuan.(2)I estimate the direct household carbon emissions, the indirect household carbon emissions, the sumptuous household carbon emissions, the basic household carbon emissions.The results show that indirect carbon emissions are more than direct carbon emissions, and the proportion of indirect carbon emissions in total household carbon emissions reach80.33%.the sumptuous household carbon emissions account for a very small proportion in the total household carbon emissions in the urban family, it’s only10.94%.(3)I analysis the influence factors of household carbon emissions, including the geographical environment, demographic factors, and income. The results show that the geographical environment has some influence on household carbon emissions; the family size has little positive effects on the household carbon emissions, there the population aged15-49years has little negative correlation with the household carbon emissions; per capita household income doesn’t have correlation with household per capita carbon emissions, but the average income level significantly impact on the average household carbon emission levels, in addition to average income levels also affect the indirect carbon emissions and the proportion of sumptuous carbon emissions.
