The International Union for Conservation of Nature and Natural Resources (IUCN) is the world’s largest environmental network that greatly contribute to environmental law. The IUCN provided technical support to the implementation of the Convention on International Trade in Endangered Species of Wild Fauna and Flora and to the ratification of the 1973 International Agreement on the Conservation of Polar Bears. The IUCN also fulfils important functions in the global governance of environmental affairs. For example, in cooperation with the UN Environment Programme and the World Wildlife Fund (WWF), the IUCN published the World Conservation Strategy and the World Charter for Nature.
