Discussion: In Iran's criminal system, environmental terrorism has not been considered as an independent criminal behavior, with specific elements and specific conditions, However, due to the inherent of the behaviors related to environmental terrorism, this type of terrorism is inherently reprehensible, and as a rule, it can be included in various legal elements in the criminal laws, and on the other hand, due to the analogy of some elements of this criminal phenomenon with the destruction of the earth, According to jurisprudence, significant examples of environmental terrorism behaviors can be considered as examples of corruption in the land subject to Article 286 of the Islamic Penal Code (approved in 2012). However, in the set of regulations in various fields, some deterrent criminal contrivances are visible in the form of obstruction crimes, which are effective in the process of preventing environmental terrorism and play an effective role in the effectiveness of the criminal policy of counteraction.
