The environment suffers enormously during armed conflicts and, despite the increasing awareness of the pressing need to protect the planet, devastating environmental damage can occur legally at times of war. This book suggests that – apart from the protection offered under law of armed conflict – environmental treaties or multilateral agreements (MEAs) can complement and strengthen environmental protection when war occurs. Previous research has focused on the protection offered under the law of armed conflict (in particular international humanitarian law) and customary international environmental law concerning wartime environmental damage, or whether environmental treaties remain applicable at times of armed conflict. This book, however, is the first in-depth scholarly examination of how environmental treaties can apply in wartime and how they can contribute to the protection of the environment in relation to armed conflict. an updated study of environmental protection under the law of armed conflict, including the latest developments in the International Law Commission's work on this underexplored topic.
