Abstract: The restart of Chinese Certified Emission Reduction has brought development opportunities to forestry carbon sinks with emission reduction potential. This paper, for the first time, based on the framework of new institutional economics, explores the institutional supply and demand relationship and model innovation mechanism of CCER forestry carbon sink asset securitization, proposes the transaction structure design of "dual SPV + fund trust", and analyzes the internal logic of its financing model innovation. However, at present, the practice of CCER forestry carbon sink asset securitization is still constrained by the instability of underlying assets, the imperfect structure and policies of the carbon trading market, the low participation of financial institutions, and the incomplete third-party service institutions. In the future, CCER forestry carbon sink asset securitization can be achieved from: Draw on international standards to improve the methodology of forestry carbon sinks. On the basis of optimizing the carbon sink measurement, monitoring and accounting system, improve its asset pricing mechanism. While improving the carbon market trading mechanism, enhance the efficiency and transparency of carbon sink trading. Vigorously strengthen the policy support system of the carbon market and actively encourage key breakthroughs in carbon trading financial innovation.
