Abstract: A scientific and reasonable pricing mechanism is the key to forestry carbon sink trading. It plays a decisive role in revitalizing the forestry carbon sink market, mitigating global climate change, and realizing the“double carbon”goals. While some countries and regions have actively explored pricing mechanisms for forestry carbon sink products and have accumulated valuable experience, a unified and mature pricing mechanism for forestry carbon sinks is still lacking. In this study, we first systematically review the pricing mechanisms of forestry carbon sink products in typical domestic and international trading platforms. Subsequently, a comparative analysis is carried out across multiple dimensions, including the types of forestry carbon sink products, pricing principles, pricing theoretical models and information levels, pricing constraints, membership management systems, pricing supervision, and pricing settlement. Finally, in light of the current situation and challenges surrounding the pricing practices of forestry carbon sink products in China, seven inspirations are proposed by integrating relevant economic pricing theories and typical pricing experience: 1) Establish the legal market rules and standards for the forestry carbon sink pricing mechanism. 2) Optimize the carbon quota adjustment price mechanism for forestry carbon sink pricing. 3) Adjust the market supply and demand mechanism for forestry carbon sink pricing. 4) Develop the pricing mechanism for high-quality forestry carbon sink products. 5) Build an information trading platform for the forestry carbon sink pricing mechanism. 6) Improve the regulatory system governing the forestry carbon sink pricing mechanism. 7) Cultivate a professional team dedicated to the forestry carbon sink pricing mechanism. The results can provide a scientific basis for improving the pricing mechanism of carbon sink products and promoting the development of the forestry carbon sink market, thereby facilitating the achievement of the“double carbon”goals.
