Abstract
With an attempt to realize the effectiveness of a university's policy on motorcycle emission, this study compared its students’ participation behavior, associated knowledge, and attitudes toward relevant environmental issues with those of three other universities without similar measures. The results of a survey on a total of 504 students revealed that the measure brought changes to the participation behavior of the students and this behavioral change could increase their intention of buying electrical motorcycles. However, the effect in which behavioral change extended to the changes in attitudes and knowledge of broader scope was not significant for overall students. Possible reasons concerning individual involvement and the necessity of educational programs were discussed.
