As has been stated earlier, international environmental law would be applying international law to environmental issues. If one were to identify a few international environmental problems to be climate change, ozone depletion and pollution, it would appear that there does exist a body of international law that could be applied to the problems such as the United Nations Framework Convention on Climate Change and the Convention on the Depletion of the Ozone Layer.As noted above, there is a large body of multilateral laws on environmental issues which are binding on the state parties. However the main reason why doubt exists as to whether or not there is such a thing as international environmental law is based around the ‘softness’ of most of the laws. Some writers have argued that at most, what exists with regards to international environmental law is a set of environmental principles which have evolved from the application of principles of general international law to environmental issues (Brownlie, 1999; pp 283-284). The question here would be how far the application of these principles has evolved to the extent that they may be considered international environmental law.
