The results for environmental knowledge, attitude and practices were analysed using SPSS version 20 and were tested by using Cronbach Alpha test to test reliability before the actual studies. In this study, the result of independent t-test had shown that the environmental awareness of male is higher than female. Besides, the second-year and third-year student has higher environmental awareness compared to first-year student. Chinese students were recorded to the highest environmental awareness compared to Malay, Indian and other races. The result shows that the duration of study has affected the student awareness. Thus, environmental education has played an important role to spread awareness among students.
