During the open aggression of Israel and the US against the country of Iran in the 12-day war, we witnessed numerous environmental and ecological damages. Following this aggression, the Iranian Environmental Protection Organization also issued a statement stating, "Unfortunately, the recent 12-day imposed war and the aggressions of the Zionist regime forces have caused serious and irreparable damage to these natural assets" On the other hand, according to the rules and principles of international environmental law, the use of methods or means of war with the intention of causing severe, widespread and long-term damage to the environment is prohibited. The environmental damages of this war, in addition to affecting wildlife, destroying vegetation, damaging soil and killing animal species, disrupting food chains and reducing biodiversity, will also have negative effects in the field of climate change. In this study, using a descriptive-analytical method, the environmental and ecological damages of these crimes and the ways to pursue them through international institutions will be examined from various aspects of green criminal science.
