The GHG emission determinants research for waste disposal process at city-scale in Baoding

Current research on greenhouse gas(GHG) inventories supports the view that waste disposal is an important source of urban GHG emissions. Studying the driving factors behind the changes in greenhouse gas emissions from municipal waste treatment can provide better information support for emission reduction. This paper systematically evaluates the city-scale GHG emission determinants in waste disposal process using a system dynamics model. Subsequently, an empirical analysis was conducted on Baoding City. This research brings some interesting results: (1) The impact of the population is paramount. The emission reduction effect of controlling the size of the city and improving the quality of the population is remarkable. (2) Policy is another key factor. Comprehensive and appropriate policies are more effective than introducing and applying advanced technologies. Including urban land management, waste separation and metering and charging can be used for it. (3) It is necessary to formulate appropriate emission reduction policies for different industrial sectors by focusing on GHG generated from solid waste. Because the combined effect of factors is not equal to the simple sum of each factor. Policy implications in terms of our study results are discussed.
