Environmental risks management and assessment become essential in dealing with environmental pollution events when we pursue green environment and sustainable transportation policies. Hence, this article investigates the environmental risk perceptions of residents living in neighborhood of east Keelung Port in Taiwan. Using surveyed data collected from questionnaires, the multiple linear regression (MLR) model was used to examine the research hypotheses. We obtained several important findings in this empirical study. Firstly, the risk perceptions index of local residents indicates that pollutions produced in port operations become serious threats to health. Secondly, compensation effect, psychological factors, trust, demographic factors and physical environment were found to show influential effects upon risk perceptions of local residents. Local residents showed higher risk perceptions when they believed their daily lives were impacted more serious. Also higher trust toward Taiwan International Ports Corporation (TIPC) heightened risk perceptions. On the opposite, higher trust toward relatives, friends and environmental groups led to low risk perceptions. The people lived farther away from port areas showed lower risk perceptions, too. Besides, groups of ‘female,’ ‘higher educated people,’ and ‘longer living duration’ also showed higher levels of risk perceptions to local pollution risks. Finally, we studied the managerial implications in this article and proposed several recommendations for government to gain supports and trust of local residents.
