The conflict in Ukraine is not only taking a heavy toll on human lives but also significantly impacting the environment and wildlife. Many natural areas have suffered extensive damage, and numerous animal species face even greater threats. It is concerning that many ecosystems may never recover their former biodiversity. This environmental disaster, culminating in the destruction of the Kakhovka dam, prompts questions about whether such actions can be denounced as acts of ecocide. This article aims to provide an overview of the ecological and legal landscape regarding allegations of ecocidal acts committed during the Ukrainian War. To this end, the first section of the paper will outline a non-exhaustive list of potential ecocidal crimes that occurred during the conflict in Ukraine. Subsequently, we will examine the opportunities and limitations associated with applying the concept of ecocide as a crime during the war in Ukraine. Finally, we emphasize the necessity for reforming environmental law to incorporate the concept of ecocide as a crime.
