In order to reach the goal of sustainable development and carbon reduction, the governments expect to build up the high quality of environment in cities. In line with Environmental Protection Agency (EPA) statistic data, individuals spend above 90% of time staying in indoor spaces everyday. Thus, whether the quality of air is good or bad, it straightly impact on peoples’life quality and health. The bad quality of air in cars of public transportations may cause by inappropriate ventilating system. In this case, passenger would expose in such unhealthy environment. This study especially aims to investigate the concentration of carbon monoxide and carbon dioxide in trains cars, Taiwan high-speed rail cars, MRT cars, and buses. 　　The period of monitoring began from March in 2014 to April in 2014. And the results of data we monitored are as below: 1.The carbon monoxide concentration for our indoor objects are all below the threshold set by EPA for indoor air quality. 2.The indoor carbon dioxide concentration during in off-peak is lower than the one in peak. 3.According to the result of monitor the concentration of carbon dioxide which inside trains obtained in rush hours we found the exceeds the indoor air quality standards set by EPA. 4.Regardless of in peak or off peak, the result shows that the concentration of carbon dioxide in Chiayi BRT buses, Kaohsiung city buses, and bus in highway all exceed the standard set by EPA. 5.The result of study reported that both in peak and off peak, the concentration of carbon dioxide inside Taiwan high-speed rail cars, meet the standard set by EPA.
