Summary

       In recent years, with the industrialization and rapid development of the economy, the serious air pollution has caused many negative impacts on health and environment. In Taiwan, all air pollutants have already been in control except PM2.5. Exposure to high concentrations of PM 2.5, not only increases the risk of all-cause mortality and the risk of cardiopulmonary diseases, it is also associated with lung adenocarcinoma. From the above, lowering PM2.5 emission in Taiwan is an important topic. Moreover, Kaohsiung is the most serious polluted area among six main municipalities. Considering proportion of PM2.5 and affection to human health, this research will focus on the mobile pollution source and make a case study in Kaohsiung.
       Many improvement strategies of PM2.5 have been suggested by former research. But most of them are reduction methods for a single strategy. However, there is no solution to PM 2.5 that has already been inhaled into the body currently. Decision makers have to reduce effects of exposure to PM2.5 with limited time and funds. They must be able to prioritize strategies in order to achieve best results. This research reviews literatures and related policies around the world to formulate strategies of mobile source PM2.5. By implementing FDM with experts’ opinions, this research divides 18 improvement strategies into 5 dimensions (Legislative Regulation, Policy Promotion, Social Education, Environment & Sharing Economy and Technology Change) and identify the priority and achievability by FAHP and IAA. This research finds out that ‘new emission standard’, ‘old diesel vehicle elimination’, ‘examination of vehicles’, ‘electric vehicles subsidy’, ‘development of charging stations’ and ‘novel battery in electric vehicles’ are important and highly feasible.
