The law of war historically paid scant attention to the protection of the environment. Its main focus was to regulate hostilities so as protect combatants from unnecessary injury. Since World War II, it has turned to the protection of the civilian population and individual civilians. It does not follow that the environment did not receive any protection at all. In as much as international humanitarian law places constraints on the use of means and methods of warfare, the environment was indirectly protected. Thus, the provisions of the Hague or the Geneva Conventions, through the protection of civilian property and objects, offer indirect protection of the environment. Similarly, the banning of weapons of mass destruction, such as biological and chemical weapons, or the restraints on activities related to nuclear warfare, such as the testing of nuclear weapons, also ultimately limit potential damage to the environment caused by armed conflicts.
