ABSTRACT Waste-to-energy (WtE) can not only generate energy in the municipal solid waste disposal process, but also reduce greenhouse gas emission. Taking two WtE methods (incineration with energy and landfill with landfill gas utilization) as objects, this paper calculated the gas emission reductions of the two WtE methods in northern and southern cities in China. This paper researched the synergistic effect of greenhouse gas emission reduction and waste disposal, and then made cost-benefit analysis for WtE methods under per unit greenhouse gas reduction. This paper includes two parts. The first part is to analysis the appropriate WtE method for different cities by comparing the synergistic reduction effect of WtE methods between northern and southern cities in China. Such can help to provide the basis for the construction of WtE projects in different cities. The second part is to analysis the impacts of carbon trading revenue and tipping fee to the cost-effectiveness of WtE methods by comparing the costs and benefits of WtE methods between typical northern and southern cities in China. Such can help the local government develop appropriate tipping fee and other related systems. Without considering the CO2 of biogenic origin, the reductions for landfill with –1 landfill gas utilization are bigger in southern cities (905~999 kg CO2e t –1 MSW) than in northern cities (529~767 kg CO2e t MSW). And the values for incineration with –1 energy are substantially the same, 810~1092 kg CO2e t –1 MSW in northern cities and 754~1057 kg CO2e t MSW in southern cities. It deserves attention that CO2 of biogenic origin has a greater impact on the accounting results. There is relatively large potential for WtE projects in southern cities and the cost-effectiveness is very good for landfill with landfill gas utilization there. Government should give priority to supporting the southern cities to carry out WtE projects. Even without carbon trading, as tipping fees paid by local
