Advantages,Challenges and Countermeasures of Developing Coastal Blue Carbon Sink in China in the Background of Carbon Neutrality

Coastal blue carbon plays an important role in the global climate change and carbon cycle. Ecological restoration and market trading can effectively improve coastal blue carbon sink, which is a cost-effective way to achieve carbon neutrality. In order to explore the potential of coastal blue carbon to promote the realization of carbon neutrality, this paper elaborated advantages of developing coastal blue carbon. At the same time, this paper analyzed the problems faced by coastal blue carbon development in system construction and technology development, then put forward the countermeasures and suggestions: improve the policy measures of coastal blue carbon conservation and carbon sink trading, and promote the mechanism construction of land-sea coordination and ecological compensation. Promote the development of blue carbon greenhouse gas inventories and participation in international cooperation. Set up monitoring and assessment pilots to improve carbon sink measurement and accounting methods. Strengthen the scientific research and radical technical bottlenecks.
