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 × 10 tons for NO, 2.1037 × 10 tons for SO, 2.291 × 10 tons for PM, and 2.921 × 10 tons for PM 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., SO and PM) is most affected by the ECA policy. However, the NO 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.
利用 2017 年的 AIS 数据，本研究旨在探讨上海港水域五个 ECA 政策对商船污染物排放的有效性。结果表明，2017 年货船（包括散货船、集装箱船和油轮）的估算年排放量分别为：NO 为 3.4029×10 吨，SO 为 2.1037×10 吨，PM 为 2.291×10 吨，PM 为 2.921×10 吨。影响分析结果突出表明，每个 ECA 政策对不同商船类型和不同水域的影响差异显著。货船（如 SO 和 PM）的污染物排放量受 ECA 政策的影响最大。然而，不同的 ECA 政策对 NO 排放没有显著影响。结果还表明，未来的 ECA 政策可能会使洋山和吴淞水域的污染物排放量大幅减少。
