According to the report from “Civil satisfaction investigation for environmental protection policy” in 2012, the consequence of research of outdoor air quality indicated that the people were persecuted with the air pollution which caused by high polluted vehicles in the last year was 41.4%. Due to the high density of population and lack of the buffered areas between different land uses, the average vehicles owned per person was high. An average of 1 vehicle (motorcycle or automobile) was owned by each 0.95 person. In terms of statistical figures from A.Q.M.C (Air Quality Model Center) in 2009, CO pollutant resulted from motorcycles was 71.2 percent of all CO emission in Taiwan. HC and NOx were 25.5 % and 46.8 % respectively. Therefore, if we have a proper strategy to control and eliminate the high-pollutant emitting vehicles, the air quality could be improved effectively. In order to manage all high-pollutant emitting vehicles with limited inspectors, we established the high-pollutant emitting vehicles reporting system in 2000. This year, new functions were added and system was maintained, and total rewards worth more than one million NT dollars lottery event for tipsters was held. Above all, two training programs and two conferences took place during the duration of the project. Through the programs and conferences, environmental protection government agencies had communicated with each other and exchanged successful experience in polluting vehicle reported area and came to many consensuses. Information system functions were also modified and updated consequently, and processing quality was greatly improved. The project team developed E.P.A. “Mobile Pollution Sources Information system”, included national performance E-report, and established intranet book system to maintain the information and schedules. The book system contained important check points and schedules of all projects or events. Furthermore, project team integrated databases delivered by all the projects and consolidated data to provide integrated information as an important reference for line pollutants, decision making platform. All the consolidated information could be saved and applied for all the purposes upon different needs. According to statistics, 461,014 suspect vehicles were reported by Dec. 31, 2012. It has effectively contributed to emission reduction in 2012. In motorcycle category, emission was reduced approximately 399.58 tons in NMHC and 1373.52 tons in CO emission. In diesel vehicles category, it was reduced 126.31 tons in TSP emission. In gasoline vehicle category, it was reduced 1.65 tons in NOx emission, 8.26 tons in NMHC emission, and 74.46 tons in CO emission. The fruitful results indicated the project performed excellently among line-source pollutants strategies. The program has shown it’s valuable and should be developed further.
