ABSTRACT
Facing rapid urbanization and industrialization, China is under great pressure to achieve both carbon emissions reduction and air pollutants control. It is more important to forecast future situations than historical emissions so that effective measures can be taken going forward. This chapter considers future forecasts of co-benefits of air pollution and low-carbon measures in Chinese mega-cities by integrating the GAINS-China model and the AIM/CGE model. Chinese cities contribute around three quarters of national GDP and we consider the four largest cities, namely Beijing, Tianjin, Shanghai and Chongqing, as case areas to evaluate the co-benefit of air pollutants from low-carbon mitigation measures. The chapter gives the key characteristics of Chinese economic centres. Both the co-benefits of emissions reduction and cost reduction after implementing mitigation measures are studied in the chapter. Different stages of development should correspond with different policies in order to produce an adequate response to environmental problems.
