Profile | Economic development and population growth have led to an increase in the use of transportation services. This, in turn, has led to an increase in environmental problems caused by transportation. The environmental problems caused by transportation include CO2 emissions that cause global warming, air pollutants, noise, and vibrations, and so on. The cost of environmental impacts to societies is said to amount to 4-5 percent of a country's GDP in monetary terms. Then, it is desirable for governments to control and reduce these environmental problems caused by transportation. The main policies used to reduce and control environmental problems caused by transportation are technological regulations. However, there are many cases where technological improvements are approaching their limits. This means that technological regulations alone cannot sufficiently reduce environmental impacts from transportation. Therefore, market-based measures are gradually being introduced to curb transportation-related environmental problems by providing incentives to change people's behavior to reduce the environmental impacts. On the other hand, there is still a lack of knowledge about the effects of market-based measures, except for some transportation modes and policies. Therefore, the main research conducted is to evaluate the effectiveness and evaluation of market-based measures to reduce environmental problems induced by the use of transportation by numerical simulations. The transportation modes targeted are automobile transportation and international shipping. We have carried out a computer simulation on road pricing policy, a numerical simulation of partial equilibrium analysis on transactions of fuel efficiency figures, and numerical simulation on an Emission Control Area. We have also studied the environmental problems from theoretical and empirical perspectives. In the former, we analyze the behavior of shipping companies in the international shipping market from a dynamic perspective. As for the latter, we are conducting empirical analysis on the effects of environmental impacts caused by automobile transportation due to changes in population composition. |
