ABSTRACT
This chapter proposed a unifying framework that incorporated a number of models and databases to explore the spatial changes in CO2 emissions due to the emission trading scheme (ETS) in Hubei, one of China's ETS pilots, simulate the distribution of atmospheric co-pollutants on a 3 km × 3 km resolution, and compare the cause-specific mortality attributable to co-pollutants varying in time and cross regions between with and without the ETS. The simulation shows that in general, the ETS improved air quality in large parts of Hubei, as indicated by the notable decline in both PM2.5 concentrations and the proportion of heavily polluted areas throughout Hubei. However, an increase in PM2.5 concentrations after the implementation of ETS was observed in some areas of major cities, such as Wuhan, Xiaogan, Ezhou, Huangshi, and Yichang, resulting in negative impacts on human health locally. The findings could assist policymakers in better understanding the complex impacts of ETS on environmental and human health, therefore serving as a useful reference for interregional efforts to speed up the development of China's ETS.
