Outline of Final Research Achievements

This study develops a basic model and numerical simulation to analyze how a country might determine the optimal boundary of an Emission Control Area (ECA). First, the model deduces an optimization condition on setting ECA size. Second, this study analyzes the costs and benefits of ECAs by changing their sizes and determines optimal ECA size by using a numerical simulation including the decision making required to alter ships’ locations in the sea area as well as a dispersion model of air pollutants from shipping. The simulation also provides the marginal cost curve and marginal benefit curve to determine the optimal ECA size. The marginal analysis implies there are two optimal points for ECA size. Changing such parameters as the value of life, population density, and the price of low-sulfur fuel clarifies their relationships with optimal ECA.
