Abstract
To control emissions from vessels, the establishment of emission inventories is a basic work. The paper first calculates emission inventory from vessels in the Pearl River Delta (PRD) region using the bottom-up method based on Automatic Identification System (AIS) data, then analyses the emission characteristics, and based on which, the reduction effect of several emission control measures is discussed. The results of the study show that vessels in the PRD region emitted a total of 18,900 tons of SO2, 284,800 tons of NOx, 24,300 tons of PM10, 70,800 tons of HC, and 18,400 tons of CO in the year of 2017; emissions of atmospheric pollutants are highest under the mode of Slow-steaming, and lowest under the mode of Anchored; emissions from vessels are mainly concentrated in the port area and near the channel; China’s scheme of domestic emission control areas (DECAs) for vessels can have a good effect on sulfur oxide control.
