The enforcement of international environmental law in various legal systems is one of the most up-to-date contemporary international law issues. In this regard, Article 9 of the Iranian Civil Code has provided a solution for implementing international treaties. However, in addition to its interpretation, it could not be applied to other international law sources such as international customary law or decisions of international courts. This article aims to examine the different approaches to implementing international environmental law in the domestic law of countries with a view of the Iranian legal system. Based on an analytical approach and an inductive approach, this study also considers possible legislative solutions for effective international environmental law enforcement in Iran. Investigations and studies of this research have shown that there are credible legal capacities in the Iranian legal system for effective enforcement of international law despite legal uncertainties and enforcement constraints. At the same time, it is necessary to enact laws and regulations to clearly explain the relationship between Iranian domestic law and international customary and contractual obligations.
