The cost of mitigating climate change is estimated at 200-350 billion Euros (236-413 Billion USD) per year by 2030. It is a manageable sum in terms of a global burden, only 1% of global GDP. In terms of who pays and how much to pay, however, it becomes a disputed figure. For example, developed countries agreed in 2010 to “mobilize” 100 billion USD annually by the year 2020 in paragraph 98 of the COP16 decision 1/CP.16. Unresolved issues regarding this commitment remain, even in 2017.
Philosophically, this divide has on one side the developed countries as having the ability and the responsibility to pay. Developed countries use more energy than under developed countries. On the other side, the underdeveloped countries need financing and the know-how to ensure that future development in their countries is environmentally friendly and sustainable.
At COP23, this issue came to the forefront where it stopped the APA closing plenary dead in its tracks on Wednesday afternoon, the day the APA was scheduled to close. Negotiations lasted through the night. The underdeveloped countries, led by the G77, wanted developed countries to make concrete commitments through the biennial communication requirements as required by Article 9.5 of the Paris Agreement. The G77 also referred to Paris Agreement Articles 13 (transparency) and 15 (compliance) to make this requirement enforceable.
In response the developed countries argued that Article 9.5 is a procedural matter and that the G77 countries want to discuss the dollar commitments. They argued that this is beyond the scope of the Paris Agreement.
The result was to urge both sides to act on their commitments and to refer this matter to a High Ministerial Dialogue for further discussion. In other words, onwards to 2018.
