Background--The new accounting practice of uforest carbon sinks and their transactions" under the cap-and-trade mechanism does not exist corresponding accounting standards at home and abroad, and a scientific and reasonable carbon sink accounting system is required. As the primary link of accounting, accounting recognition has become the first problem to be solved in the construction of forest carbon sink accounting system. ⑵ Methods--The data of this paper mainly comes from the CCER Forestry Carbon Sink Project Design Document (PDD) of China Voluntary Emission Reduction Trading Information Platform, and adopts the normative research method. On the basis of combing the relevant literature of forest carbon sink accounting at home and abroad, this paper examines the particularity of forest carbon sink and its impact on accounting recognition, and further studies the accounting recognition time point, accounting recognition type, accounting recognition method and the specific accounting treatment of forest carbon sink economic business. (3) Results--① Forest carbon sinks have their particularity compared with general assets and carbon emission rights quotas of enterprises. Forest carbon sinks trading is a carbon credit transaction generated under the cap- and-trade mechanism, which is essentially a carbon emission rights transaction. ② As a derivative of forest assets, the accounting recognition of forest carbon sinks should be based on the ownership relationship. When the ownership relationship between forest carbon sinks and forest assets is inconsistent, only accounting recognition of forest carbon sinks should be carried out separately. When the two ownerships are the same, forest carbon sinks and forest assets should be recognized as an organic whole in accounting recognition. ③ Forest carbon sinks are "certified emission reductions" successfully issued by the National Development and Reform Commission, which makes forest carbon sinks reach a predetermined usable state and have the ability to trade. This also gives forest carbon sinks the exclusive rights or other rights of the holders, so that they can occupy, employ and dispose of the resources and obtain future economic benefits. This means that the certified emission reduction of forest carbon sinks officially becomes an asset, so the issuance link of certified emission reduction of carbon sink projects should be used as the confirmation point of forest carbon sink assets. ④ Forest carbon sinks owned by the holders of forest carbon sinks are more in line with the nature of illiquid assets. The purpose of holding forest carbon sinks is mainly to obtain economic benefits of forest carbon sinks or reduce additional losses so that they have the nature of investment. Therefore, forest carbon sinks should be recognized as' investment carbon emission rights assets' in the type of confirmation. ⑤ As an asset of an enterprise's investment nature, forest carbon sinks are determined to be invested, that is, they are designed to invest a certain amount of cash in order to obtain more cash inflows, which means that the use of fair value measurement of forest carbon sinks can better reflect their intrinsic value. Therefore, the fair value measurement model can be considered in the recognition criteria of forest carbon sinks. ⑷ Conclusions and Discussions--The accounting recognition of forest carbon sinks should start from the property rights protection of enterprise stakeholders. Under the framework of carbon emission rights accounting standard system, the ownership of property rights should be defined through the ownership relationship between forest carbon sinks and forest assets, and the rules for accounting recognition of forest carbon sinks should be established according to the internal relationship between carbon property rights and carbon financial rights, to form a set of carbon emission rights accounting system covering forest carbon sink development, trading and offset.
