The trajectory of 21st-century warfare has fundamentally altered the relationship between armed conflict and the natural world. The environment has become a victim of combat, the casualty of industrial negligence and a source of future instability. Contrasting the industrialised ecocide in Ukraine with the infrastructural neglect in Sudan, it demonstrates the long-term and severe impacts armed conflicts have on our ever-precious environment. This dissertation will argue that despite the emergence of soft law instruments such as the 2022 ICL principles and the 2025 ICJ advisory opinions, the international law order remains stuck. It permits environmental degradation and allows systematic failures within the international legal mechanisms.
