Nowadays the climate change is one of the main concerns of International Community. This problem, since 1979, has been addressed by the United Nations. Through the several international and regional conferences the UN has progressively developed the policies and measures to face the mentioned changes. The stabilization and reduction of the emission of greenhouse gas, and the adaptation to climate change are three policies of the UN in this regard. In this regard, UN Framework Convention on Climate Change and Kyoto Protocol are presenting some legal measures for stabilization and reduction of the emission of greenhouse gas. International Community, through adoption of these Documents, has filled the normative gap in this area and could produce considerable solidarity for facing this crisis. However, the concerns regarding implementation of the mentioned international norms are remained.
