Ship emission accounting based on AIS data mining

As one of the main sources of emission, ship’s emissions cannot be ignored. Taking the ship emission in Wuhu section as an example, based on the data of AIS, the data of ship emissions in Wuhu section shows that the cargo ships emissions is the largest source of the discharge in the Wuhu section. At the same time, the amount of pollutants from the mooring ship is also large. In addition, in order to visualize the emission characteristics of the Wuhu section, a method of simplifying the calculation process using representative ship types was proposed, and the emission hot spots were plotted. This research has a certain guiding significance and value for the local emission control, and can be popularized to other areas.
