The blurry and vague outcome obtained by Copenhagen Conference intensifies public concerns about the future prospect of CDM. The concerns are entirely valid and justified: the US is still so far not a signatory of the Kyoto Protocol and it could only participate in the negotiation on renewal of the second-phase contracting period of the Kyoto Protocol as an observer, regarding the international climate, which is quite out of line with the superpower status that is always associated with the US. Hence, they attempted pretty hard to abandon the existing framework and invent a new one from scratch. In this way, the Clean Development Mechanism, which is entirely based on The Kyoto Protocol, loses its support. Nevertheless, it is believed by the author that CDM is, so far, the most successful economical and market-oriented trading mechanism of emission reductions between developed countries and developing countries. Even though it is still problematic, the issue that is at heart is how to modify and perfect it instead of replacing it entirely. Hence, the author is personally optimistic about the future prospect of CDM and equally confident in the future trends of the trading price. Before this book draws to a close, the author hopes to unveil analysis and paint the future prospect by including the observations before the Copenhagen Conference, basic comments of Copenhagen Conference, future prospect of international cooperation on climate and suggestions regarding approaches to management of emission reductions in an effort to provide a clue to those engaged in the industry of carbon emission reductions in China.
