However, such coordination remains understudied, especially at the local level. Using the principal component analysis, entropy evaluation methods, and the Coupling Coordination Degree Model (CCDM), we evaluated the level of coordination between carbon and air quality mitigation from 34 low-carbon pilot cities in China. We also illustrated the mechanism and policy formation that leads to different coupling patterns at the local level using three case studies. We found that most pilot cities perform a medium level of coupling coordination between low carbon development and air quality. The result reveals that most low-carbon pilot cities score relatively well in low-carbon development. Further, there is a significant cleavage in air quality between cities in the North and those in the South, indicating pilot cities in the South coordinate better than those in the North. In particular, pilot programs in the Southwest and Southeast coastal region perform well in collaborative governance, while the Beijing−Tianjin−Hebei region is rated poorly because of the gap between air quality and low carbon development. Also, we found that the same low-carbon policy might have heterogeneous effects on different air pollutants and across different regions. The local government should adopt low-carbon development policies that address local level specific environmental and economic conditions to maximize their air pollution mitigation benefits.展开更多
