Globally, the debate and discussion about climate change are conducted along two tracks. One is science-based named “The Intergovernmental Panel on Climate Change (IPCC)”, and the other is a policy track controlled by the “United Nations Framework Convention on Climate Change (UNFCCC)’. The treaty (UNFCCC) provides different responsibilities for the three types of signatory states. These categories are advanced countries with special financial responsibilities and backward or developing countries. Advanced countries are also known as developed countries or Annex 1 countries. Advanced countries must adopt national schemes and take appropriate measures to mitigate climate change by limiting anthropogenic greenhouse gas emissions and report on measures adopted, individually or collectively, to restore the 1990 emission levels.
