The Annex VI on "Regulations for the Prevention of Air Pollution from Ships" in MARPOL 73/78 was revised to progressively reduce air pollutant emissions. The revised Annex VI went into effect in July 2010. This study estimated changes in air pollutant emissions from ship after the effect of the revised Annex VI and impact of the change in emission on air quality. For the estimate of change in ship emission from the present to 2050 in Japan, following assumptions were applied: the life of ship is 35 years; shipping tonnage is constant. The total amounts of NO_x and SO_x emission in the study region are expected to be decreased by 17.5% and 24.3% between the present and 2050, respectively. The WRF/CMAQ modeling system was utilized to predict the impact of the ship emission regulation on air quality in Kinki area. The results show that combination of ship emission regulation and land base VOCs regulation is more effective for the decreases of air pollutant concentrations in larger area.
