Understanding undergraduates’ environmental behaviour is important as they will be the leaders of the
country in the near future. They play an important role in protecting and conserving the environment.
This paper investigates the undergraduates’ behaviours towards the environment after completing the
Environment Economics course. Theory of Planned Behaviour (TPB) together with some other factors
such as academic performance, government regulations and perceived importance of nature are
employed. Multiple regression analysis shows undergraduates’ behaviours is positively affected by
attitude and perceived importance of nature, and negatively influenced by government regulations.
Although academic performance is very important to provide an understanding of basic principles of
environmental sustainability, it however does not significantly influence their environmental
behaviour. The finding hopes to assist the policy makers to plan future strategies so that the
undergraduates behaviours can make a difference to nature and the environment.
