Analysis of the legitimacy of carbon tariffs—from the perspective of Habermas's legitimacy theory

The legality of carbon tariffs has been highly controversial since their inception. Habermas's discussion legitimation theory believes that the legitimacy of a rule depends on three requirements: the acceptability of its value, the legality of the rule itself, and intersubjectivity. The existing carbon tariff rules do not meet the above three requirements at the same time, so they are not legal, but they may have legality in the future. When designing a system, it can be permitted if it meets the above requirements.
