The number of motorized vehicles grows with the fast development of industry and commerce. The monthly report of Ministry of Transportation and Communications (MOTC) shows that there are 22,252,156 motorized vehicles in Taiwan up to the end of Oct 2012, and 291,189 of them are registered in Chiayi City. The increase of number of motorized vehicles has significant impact on air quality. With the public cries for better environmental quality under the growth of per capita household income, environmental protection authorities are paying more and more attention on deterioration of air quality due to emission from motorized vehicles.
A report of UN indicates that cars running on idle for 10 seconds consume more fuel than at engine startup. Nippon Institute of Technology conducted a study program that shows most of pollutants emitted from a car running on idle for more than 30 seconds (e.g. CO, HC, NOx and CO2) are more than produced at starting up the engine. Therefore, turning off the engine at parking does reduce fuel consumption and the emission of air pollutant and CO2. It has a positive meaning of improvement in terms of energy conservation, human and health.
Up to Dec 14, the program team organized or arranged 1 presentation for idle stop for large vehicles with 2,500 participants; 2 seed trainer training meetings; short audio/video production of idle stop to be played on radio (220 times) and cable TV (400 times); production of 100 posters of idle stop at parking lots across the city; and rental of 10 buses from Chiayi Bus for advertisement on car bodies and in passenger cabins for idle stop. 881 cars were inspected for idle stop during tours of inspection with an achievement rate of 176.2%. Roadside auditing for idle stop was conducted on 514 cars for an achievement rate of 102.8%.
The following are the effects achieved for this program:
1. The data of Environmental Protection Administration shows that it is estimated annual reduction of 4.74 tons of VOC, 76.45 tons of CO, 1.40 tons of NOx and 1,953 tons of CO2 with the promotion and auditing of this program. It really helps the improvement of air quality and energy conservation.
2. 2 seed trainer meetings were held with 50 entities and 54 people participating. With these seeds spread in government agencies and schools where this program aims to start with, it will be able to set a good example for drivers. Also from teachers to children and in turn to their parents, the government policy will be realized for both health and environmental protection.
3. For the auditing of vehicles without idle stop, the strategically planned auditing locations and adjustment every month improved the auditing benefits from 2% reduction of violations at the beginning to approximately 60% through the middle of the program. It indicates that the auditing and promotion are on the right track as planned. The well thought-out and efficient auditing and supervision as well as the promotion of idle stop have made a success by reducing the violation by 45%, which is 15% lower than at the middle of the program, indicating the initial goal of idle stop promotion is achieved.
