Abstract:

The 21st Conference of Party (COP21) held in Paris at the end of 2015 has opened a new era for the joint response dealing with climate change globally, and built up a new mode of global climate governance, that is, “all Parties submit INDC-global stocktake-enhance efforts of actions-all Parties resubmit INDC-finally achieve the ultimate objective of the Convention”. With 160 INDC copies (covering 188 Parties) that the UNFCCC secretariat has currently received as research objects, this study classifies the mitigation targets of all Parties, and focuses on the systematic analysis of the financial demands, mitigation cost and priority investment fields for developing countries. The results are as follows: among 160 INDC copies, 122 copies clearly include the financial content; 64 copies propose specific amounts of financial demands for the implementation of INDC; 31 copies pre-estimate domestic amounts and financial demands for greenhouse gas mitigation by 2030, based on which they have calculated that the average mitigation cost for developing countries by 2030 will have reached up to 22.3 US$/t CO₂; 28 Parties reclassify the financial demands for mitigation and adaptation areas, and reach the conclusion that the overall financial demand ratio for mitigation and adaptation is 1.4. The current mitigation commitments of the Parties from developed countries should be used as benchmark, then by 2030 the total amount of financial demands for developing countries in response to climate change would have reached up to US$ 474 billion.
