Abstract
The environment represents a very particular area of international politics. As it constitutes a non-rival and a non-excludable good, this issue crosses the borders of all nation-states. The concerns regarding environmental damages affect all nations. Garrett Hardin, who developed the metaphor of the "Tragedy of the Commons", raises one of the most famous illustrations on this claim. In his article, he explains that a shared resource can be destroyed if everyone acts independently, pursuing selfishly his own interests. This reasoning can easily be applied to environmental issues. Negotiations between states are becoming more and more frequent on the international stage, as concerns are rising about the consequences of ozone depletion and climate change. Consequently, the debate around how to explain the developments of global environmental politics has led to the emergence of various theories or models. Some authors put forward the centrality of the states in the process of governance.
