Abstract
Climate change and pollution are threatening sustainable environments and human life. To mitigate and adapt to the effects of such threats, governments around the world need significant financial resources. Accordingly, this study focuses on which factors are associated with individuals' support for taxation to protect the environment and pays special attention to the direct effects of civic morality and political trust, as well as their joint effects on support for environmental taxation. Ordered probit results with a sample size of 760 demonstrate that civic morality is positively associated with individuals' support for environmental taxation; political trust works in the same way. More importantly, political trust moderates and enhances the linkage between civic morality and support for environmental taxation, demonstrating that it can serve as a powerful tool in a government's efforts to protect the environment.
