Over the past decade, environmental justice has emerged as one of the most important value as well as most researched topic in the area of environmental studies. This research studies Taiwanese people's understanding and support of environmental justice by analyzing a survey research. We found out that Taiwanese people have strong supports of environmental justice in principle. However, in specific environmental justice related topics, the supports tend to be weakened and varied. The variation is most significantly shown with differences in the respondents' age, education, and family income.
