Direct and Indirect Carbon Emission from Household Consumption Based on LMDI and SDA Model: A Decomposition and Comparison Analysis

Household consumption has become an important field of carbon dioxide emissions. Urban-rural disparity in the household carbon emissions (HCEs) of residents and their influencing factors are relevant to HCE reduction. Taking Fujian as the study area, the LMDI and SDA models were used to analyze the effects of influencing factors for the direct household carbon emissions (DHCEs) and indirect carbon emissions (IHCEs) of urban and rural residents from 2006 to 2018. The HCEs continue to rise, approximately 65% from the IHCEs in 2017, and urban areas occupied 67% in 2018. The gap between urban and rural per capita HCEs is narrowing. In 2017, approximately 75% of urban per capita HCEs came from the IHCEs, while the per capita DHCEs' occupation exceeded the IHCEs in rural areas. Per capita consumption expenditure has the largest positive effect on the DHCEs and IHCEs in urban and rural areas. With the urbanization process, the inhibition effect of rural DHCEs is larger than the positive effect of the urban DHCEs, while the positive impact on urban areas is more substantial than on rural areas in the IHCEs. Combined with regional differences, urban and rural areas should take common but differentiated emission reduction responsibilities.

Automated summary

Household consumption is an important field of carbon dioxide emissions, and the disparities and influencing factors of household carbon emissions (HCEs) between urban and rural residents are relevant to emissions reduction. Taking Fujian as the study area, the effects of influencing factors on direct household carbon emissions (DHCEs) and indirect carbon emissions (IHCEs) of urban and rural residents from 2006 to 2018 were analyzed using LMDI and SDA models. The study found that HCEs have been continuously rising with urban areas contributing a higher proportion, but the gap between urban and rural per capita HCEs is narrowing. Per capita consumption expenditure has the largest positive impact on carbon emissions in both urban and rural areas.
