Outline of Final Research Achievements

In order to evaluate the environmental impact of air pollutants which are discharged from ships, this study applied a methodology to estimate the emissions that is based on AIS(Automatic Identification System) data. This study also proposed the detailed methodology to determine the classification of ME, the rated output and load factor of AE, the fuel efficiency of both engines. Next, the emission factors for NOx, SOx and PM were calculated by this study and the emissions were aggregated in different ship types and offshore distances.
Finally, the meteorological fields and transport simulations were conducted by WRF and CMAQ models. The spatial concentrations of air pollutants and contribution ratios of ships were shown in Japan region.
