War is one of the most catastrophic climate emergencies. From the displacement of Indigenous peoples to its impacts on natural landscapes, war cripples vital ecologies and environmental resources and leaves ecosystems scarred long after ceasefires. Nowhere is this more evident than in the decades of Azerbaijan’s state-sanctioned violence against Armenians. As a result, forests have burned, soils have been laced with phosphorus residues, and historic landscapes sacred to Armenians have been irrevocably altered. The emerging concept of ecocide promises to fill this gap. However, its political feasibility, definitional ambiguity, and limited international enforcement capacity remain fiercely contested. Using the Armenia v. Azerbaijan proceedings before the International Court of Justice (ICJ) as a case study, this Article examines whether ecocide can be operationalized to hold perpetrators of environmental war crimes accountable or whether alternative legal tools offer a more effective path to justice.
