Calculation Of Carbon Emissions And Their Influencing Factors From Municipal Solid Waste

This research calculates the carbon emissions from municipal solid waste(MSW) in China from 1980 to 2012 and across 31 provinces in China from 2003 to 2012. The calculation uses IPCC(2006) recommended methods and is divided into four parts according to the four processing modes(sanitary landfill, simple landfill, burning, and composting) with the actual conditions of China. The carbon emissions from MSW are on the rise in China. The growth rates of MSW and its carbon emission exhibit both similarities and differences across 31 provinces in China from 2003 to 2012. Furthermore, this research analyses those factors influencing the emissions in China by using two models. The effects of tertiary industries on gross domestic product(GDP) and urban disposable income on household spending were used TSLS. The effects of MSW treatment method and household spending on carbon emissions from MSW were modeled with TSLS. And this research analyses those factors influencing the emissions across 31 provinces in China by using two models. The effects of tertiary industries on gross domestic product(GDP) and urban per capita disposable income on household spending were used OLS. The effects of MSW treatment method and household spending on carbon emissions from MSW were modeled with GMM. And this research analyses those factors influencing the emissions across eastern, central and western regions. The effects of MSW treatment method, household spending and urbanization rate on carbon emissions from MSW were modeled with GMM.The results show that the rate of tertiary industry in overall GDP and the urban per capita disposable income have an indirect positive effect on MSW carbon emissions. Urbanization rate has a positive effect on MSW carbon emissions. Reduced carbon emissions from MSW, to a greater extent, may be brought from burning and composting.
