What is the purpose of the CCPI?
According to Article 2 of the UN Convention on Climate Change, all of the countries considered in the CCPI are obliged to prevent highly dangerous climate change.
This goal should be achieved in compliance with the principle of common but differentiated responsibilities of industrialised and developing countries. The two-degree limit for global warming is of particular importance in this context, since it was adopted by the EU as a quantitative target for its climate change policy on the basis of several scientific studies.
If the increase of average global temperature stays below this limit, the danger of uncontrollable major risks will be significantly reduced. The German Advisory Council on Global Change (WBGU) therefore recommends that international climate policy must be targeted on ensuring a maximum CO2 equivalence level of 450 ppm (parts per million) in the atmosphere in order to avoid exceeding the two-degree limit.
This implies that by the middle of this century, CO2 emissions must be reduced worldwide by 45 to 60 percent and in industrialised countries by 80 percent as compared to the levels of 1990.
The Climate Change Performance Index annually compares how far different countries have come on their way to this "Olympic Goal". The trend in greenhouse gas emissions as well as the climate policy of the countries can be analysed and compared to each other at a glance.
The CCPI enhances transparency and we are glad to see that it applies pressure on governments and gives them an incentive to get active in the combat against dangerous climate change.
