The reopening of China Certified Voluntary Emission Reduction （CCER） market on 22 January 2024 in Beijing represents a major opportunity for the development of agricultural carbon sinks.From the perspective of project needs and rationales，CCER market provides a professional trading platform for the development of agricultural carbon sinks，adds ecological value to agricultural assets，and opens up non-agricultural income channels for agricultural and rural farmers,serving as a unique resource for rural areas to achieve rural revitalization and common prosperity.However,it also faces three practical needs in terms of legal response，institutional structure and development mode constructed by the market.From the perspective of problem classification and review，there are three challenges in incorporating agricultural carbon sink into the CCER mechanism：clarification is needed in terms of legal bases of property rights attribution,public-private domain at the bottom level；improvement is required in terms of legal policy-making,policy legalization,and the coordination system at the top-level design; and urgent supplementation is needed in terms of market transactions, methodological technologies,and other supporting solutions in the operational mechanism.Therefore，the legal scheme and route selection of the inclusion of agricultural carbon sink in CCER should address the following four aspects：clarification of legal bases,coordination of legal policies,improvement of cooperation mechanisms,and optimization of risk management and control.
