Abstract
The decomposition quantitative model of household energy-related carbon emission in Guangdong is established based on the extended Kaya identity with the Logarithmic Mean Divisia Index (LMDI) method. Influence factors of household energy-related carbon emission are decomposed into five factors. Main results show that total household energy-related carbon emissions in Guangdong province show increase trend from 1995 to 2016. Electric power consumption is the biggest source of household energy-related carbon emission. The results of decomposition show that population size is the first promote factor to household energy-related carbon emission in 1996-2004. Energy use level become the first promote factor in 2005-2016. Carbon emission coefficient show reduction effect, which is the first inhibit factor to energy-related carbon emission. Finally, two effective means to reduce household carbon emissions are given to Guangdong province.
Highlights
Consumption is one of the three main driving forces of economic development [1]
C is carbon emissions from household energy consumption, i is the type of energy, i=1,2,3,4, represents coal, oil, gas and power, respectively, j is the type of resident, j=1,2, represents urban resident and rural resident, respectively, Eij represent consumption of energy i by j resident, and fj is carbon emission coefficient of energy i. electric power occupies a larger proportion in the total household energy consumption, so this article will incorporate the electric power production carbon emissions into resident’s consumption carbon emissions according to electric power consumption of residents, that is, electric power will be directly included in the household energy consumption as carbon emission energy
3.1 Analysis on total household energy-related carbon emission The estimated results show that the total household energy-related carbon emissions in Guangdong province increase from 5.72 million ton in 1995 to 23.83 million ton in 2015, and decline slightly to 20.75 million ton in 2016
Summary
Consumption is one of the three main driving forces (exports, investment and consumption) of economic development [1]. Many researches show that energy consumption and carbon emissions in household of some developed countries increase year by year in recent years, even surpassed energy consumption and carbon emissions in production department [2,3,4]. China is in the crucial stage of residents’ consumption growth and consumption upgrade, with the high-speed development of social economy and the advancement of urbanization, energy consumption and carbon emissions caused by resident’s consumption will increase year by year. Liu et al [6] show that CO2 emission from household consumption accounted for more than 40% of total carbon emissions in China in 1992-2007. Even though it is difficult to promote energy conservation and emissions reduction technology , products and concept in the field of household energy use as a result of residents’ energy consumption and its carbon emissions is dispersed
