The intrinsic value and pricing of forestry carbon sinks are difficult to measure, and they are also a relatively special commodity, relative to carbon allowances, forestry carbon sinks exist in reality. The price of forestry carbon sinks fluctuates more than that of ordinary commodities, and the true value is difficult to calculate through input-output. Compared with traditional real estate, the supply and demand relationship of forestry carbon sinks is close but the price mechanism is very different. How to price forestry carbon sinks is relatively difficult, in fact, the price of forestry carbon sinks is also changing with the development of global industrialization. In the early stage of industrialization, many developed countries in line with the concept of "first pollution and then treatment" to carry out high-emission production activities, so that the original forest land area due to manufacturing expansion, mining and other behaviors seriously declined, according to statistics, the world's forests have dropped from 7.6 billion hectares in the early days of human civilization to 4.128 billion hectares in 1990, when the forestry value was relatively low. As industrial activity becomes more frequent around the world, the climate crisis is approaching, and the call for ecological protection is even stronger. In December 1997, the Third Meeting of the Parties to the United Nations Framework Convention on Climate Change was held in Kyoto, Japan. In order to prevent climate change from further threatening the living environment of human beings, the General Assembly adopted the Kyoto Protocol and established the concept of carbon emissions trading, and countries also agreed that forestry carbon sinks will play a positive role in curbing climate warming. Since then, the market value of forestry carbon sinks has also increased significantly. We can find that the value of forestry carbon sinks is mainly reflected in two aspects, on the one hand, the industrialization process and the country's attitude towards pollution reduction and carbon reduction, on the other hand, the downstream of forestry carbon sinks; ccer or cdm can offset the price of the mechanism. Of course, these two aspects are also complementary, and the value of forestry carbon sinks will continue to increase in the context of the "double carbon" goal.
