Abstract: Based on the analysis of a variety of domestic forestry carbon sink property right pledge financing models,this paper believed that the current forestry carbon sink property right pledge financing in the establishment and realization of the pledge was facing several problems,which including that the specific laws and regulations,defective publicity system,accounting and evaluation standards not uniform,lack of ways to realize the pledge,“credit+” cooperation mechanism and risk compensation mechanism not perfect.The legal solution to these obstacles was to improve the basic legal system of forestry carbon sink property rights pledge by clarifying the legal status of forestry carbon sink property rights and the responsibility of the pledger,establishing a unified accounting and evaluation system and standards,and improving the registration and publicity system.The second was to improve the implementation mechanism of forestry carbon sink property rights pledge by promoting market demand together and mitigating forestry carbon sink credit risks through multiple co-governance.
