Abstract: Global climate change has aroused extensive concern in the international community, given rise to different international organizations and catalyzed various international climate change regimes. These regimes play a pivotal and decisive role in relieving the threat of international climate change: a structuring role and the revitalizing role of a driving force, which makes different positions progress in negotiation processes and allows the set up of an international consensus and the promotion of more ambitious climate policies such as the Copenhagen Accord and the Cancún Accords. While the Copenhagen Accord involves commitment to drastically reduce GHG emissions so as to hold temperature increase below or at the 2°C threshold, the Cancún Accords concretize this goal and calls for a new 1.5°C threshold. The post2012 international climate regime must respect the equity principle, the common but differentiated responsibilities principle (CBDR principle) and bring together the whole of major GHG emitters including the United States and major developing emitters. Essentially speaking, the Measurement, Reporting, and Verification system (MRV system) in the Cancún Accords is replacing observance and is thus a quite different regime than the existing.
