Protection of environment is a matter of concern not only for individuals but for the states also. In the present era of climate change, the human environment is at stake. The whole world has become deeply conscious of its impending consequences. But the position during wars or armed conflicts among countries posits a different challenge. There are plethora of Treaties, Conventions, Protocols etc. which talks about environmental protection during wars. However, the factual position is otherwise. Recently, use of chemical weapons including deadly gases in Syria is a burning example. Now, the time has come to form a body like International Court of Justice and International Criminal Court to try and punish the perpetrators of crime against environment including armed conflicts. Otherwise in absence of effective regulators, all such International instruments will be of no avail.
