Li Nuyun's recent photo With the increasingly prominent role of China's carbon sequestration forestry in coping with global climate change, "forestry carbon sequestration" has gradually become a hot spot of public concern. On the development of forestry carbon sinks in China, we interviewed Professor Li Nuyun, Secretary-General of China Green Carbon Sequestration Foundation and Executive Deputy Director of Climate Office of State Forestry Administration. Q: What is the significance of developing carbon sequestration forestry to China's social economy? Li Nuyun: Developing carbon sink forestry can not only reduce the content of carbon dioxide in the atmosphere, but also better protect biodiversity and reduce soil erosion. Moreover, it has low cost and can bring many benefits to economic development and social progress. It has created employment opportunities and brought benefits to local farmers; In addition, although there is no carbon emission reduction target for enterprises in China, it will become a trend to require enterprises to change production methods, reduce energy consumption and reduce carbon emissions. When it is difficult to reduce carbon emissions, adopting forestry measures to absorb carbon dioxide and developing carbon sink forestry can provide a buffer period for enterprises to reduce emissions and reduce the pressure on enterprises to some extent. Developing carbon sequestration forestry and giving full play to the function of forestry in mitigating and adapting to climate change can win the right to speak and take the initiative in international negotiations on climate change for China and expand the space for China's economic development. Q: What are the requirements for establishing a carbon sink trading platform? Li Nuyun: The National Development and Reform Commission said that carbon trading can be piloted in a certain area during the Twelfth Five-Year Plan period. Carbon trading is actually the trading of carbon credit indicators, and carbon credit mainly comes from emission reduction and carbon sink. At present, the carbon market has not yet formed, and we are carrying out relevant research to prepare for carbon sink trading. There should be at least four links for carbon sinks to enter the transaction: first, there must be relevant national policies and regulations; Second, there must be products that are carbon sinks; Third, there must be a measurement and monitoring system that is in line with international standards, as well as third-party certification and registration; The fourth is to have carbon sink buyers. Q: What is the international status of China forestry carbon sequestration project? Li Nuyun: Internationally, although China's forestry carbon sink management started late, we are at the forefront of the world in the methodology of clean development mechanism carbon sink projects and forestry carbon sink management. In addition, the China Green Carbon Sequestration Foundation, a public welfare foundation established in China, has been well received by foreign experts for its operation mode and standardized management in many international exchanges. "You have done a very standardized work, and the measurement method is in line with international standards, without losing the characteristics of China and being operable." Q: What measures will be taken in the future to develop carbon sequestration forestry and cope with global climate change? Li Nuyun: The state will take more active and effective measures, increase investment, vigorously carry out afforestation, vigorously promote forest management, fully strengthen forest protection, and strive to increase forest carbon sinks to make new contributions to global climate change. Take the following measures: first, actively expand the forest area and improve the forest carbon sink capacity; Second, vigorously improve forest quality and enhance forest carbon sink function; Third, strengthen forest protection and reduce forest carbon emissions; Fourth, develop biomass energy and actively promote energy conservation and emission reduction; Fifth, advocate more use of wood and increase the carbon storage of wood forest products. Q: Why is China and even the international community paying more and more attention to carbon sequestration? Li Nuyun: Industrial emission reduction will have a negative impact on a country's economy, but the problem of global warming caused by large-scale human emissions of greenhouse gases needs to be solved urgently. Therefore, more and more experts have turned their attention to the "lungs" of the earth-forests, hoping to reduce the concentration of greenhouse gases in the atmosphere by increasing carbon sinks. Although forest carbon sink is an indirect emission reduction, its carbon sequestration investment is small, the cost is low, the comprehensive benefit is large, and the economic feasibility and practical operability are strong. Generally speaking, each hectare of forest can absorb about 10-40 tons of carbon dioxide every year.
