英文摘要	China introduced an emission control area (ECA) along the coastline of the Yangtze River Delta (YRD) region in 2016 in a bid to reduce its shipping emissions. Performed at a costal site in the YRD region from 2014 to 2018, we found a significant reduction (16-22%, p < 0.01) in vanadium concentrations, the exclusive marker for heavy fuel oil combustion, after the full-scale implementation of lower sulfur fuel change for marine ships. Another site closer to the coastline showed a larger reduction (24- 30%, p < 0.01) during the corresponding period. The reduction of vanadium was consistent with an overall decrease rate of 17% in the annual SO2 concentrations of 10 sites across the region from 2016 to 2017. We thus provide a robust assessment of the positive effects of regulating shipping emissions on air quality in coastal China. The future trajectories of shipping-related emissions are also discussed.
