Description
Technical Field

Background
Global climate change is one of the great challenges facing current world development. The degradation of the ecological environment caused by climate change, natural disasters and extreme weather pose a great threat to human society. The development of green low carbon sustainable development has become the current global consensus for climate change.
In the process of achieving the 'two carbon' goal, emission reduction and sink enhancement are two main means of achieving this goal. Carbon sink is the process, activity or mechanism by which the isothermal chamber gases, such as carbon dioxide, are purged from the atmosphere. Forest carbon sink refers to the process, activity or mechanism by which the forest ecosystem absorbs atmospheric carbon dioxide and fixes it in vegetation and soil, thereby reducing the concentration of atmospheric carbon dioxide. Forestry carbon sinks generally refer to processes, activities or mechanisms that absorb and fix carbon dioxide in the atmosphere and combine with carbon sink transactions by performing activities such as forestation and reslurry, forest management, vegetation recovery, reduction of forestation, and the like.
To achieve the "two carbon" goal, national authorities control emissions by issuing carbon emission quotas to the inclusion of forced emission reduction enterprises, and increase sequestration is achieved by increasing carbon absorption by land ecosystems, where forestry carbon sequestration is an important way of carbon absorption. Currently, when carbon emission of a certain forced emission reduction enterprise exceeds the uniformly issued quota amount, the performance cannot be completed, and then the excessive quota of other enterprises or forestry carbon amount issued by national authorities need to be purchased through the national uniform carbon transaction market to complete the performance.
