This study has investigated the components of environmental governance by usage of interval type-2 fuzzy DEMATEL. It has been distinguished that agency and adaptiveness from elements of environmental governance can determine the changes of the whole system. Besides, there are knowledge, norm, power and scale which play roles as crosscutting themes and their footprints are specified in all the elements. The results show that knowledge and norms have the ability to change the other crosscutting themes while power is more influenced by others. Such findings can help scholars to figure out how they can make the environmental governance have better performance.
