利用2017年AIS数据，本研究旨在调查上海港沃茨五项ECA政策对商船污染物排放的有效性。结果显示，2017年，商船（包括货船、集装箱船和油轮）的NOx年排放量估计为3.4029 x 10（4）吨，SO2年排放量估计为2.1037 x 10（4）吨，PM2.5年排放量估计为2.291 x 10（3）吨，PM10年排放量估计为2.921 x 10（3）吨。影响分析的结果突出了这样一个事实，即每一个ECA政策的效果显着不同的商船类型和不同的水域。货船的污染物排放量（例如，SO2和PM2.5）受ECA政策影响最大。不同的ECA政策对NOx排放影响不大。结果还表明，未来的ECA政策可以导致洋山和吴淞水域的污染物排放量更大的减少。
Using the AIS data in 2017, this study aims to investigate the effectiveness of five ECA policies on pollutant emissions from merchant ships in Shanghai Port waters. Results show that the estimated annual emissions from merchant ships including cargo ships, container ships and tankers are 3.4029 x 10(4) tons for NOx, 2.1037 x 10(4) tons for SO2, 2.291 x 10(3) tons for PM2.5, and 2.921 x 10(3) tons for PM10 in 2017, respectively. Impact analysis results highlight the fact that effects of each ECA policy vary significantly among different merchant ship types and different water areas. The amount of pollutant emissions from cargo ships (e.g., SO2 and PM2.5) is most affected by the ECA policy. However, the NOx emissions are not significantly changed under different ECA policies. Results also show that future ECA policies could cause a much greater decrease of pollutant emissions in water areas of Yangshan and Wusong.
