我国首部淤地坝碳汇方法学正式发布

Core Viewpoint - The release of the "Greenhouse Gas Voluntary Emission Reduction Project Methodology for Silt Dams" marks China's first quantitative accounting standard for carbon sinks from silt dams, providing a scientific basis for integrating soil and water conservation projects in the Loess Plateau into the carbon trading market [1] Group 1: Methodology Overview - The silt dam carbon sink methodology consists of 9 chapters, outlining the applicable conditions, boundary scope, accounting period, and carbon pool selection for silt dam carbon sink projects [1] - The carbon pool accounting primarily focuses on soil carbon pools, with plant carbon pools as a supplementary measure, adhering to conservative principles and utilizing default parameter values to reduce development and regulatory costs [1] - The methodology emphasizes that projects must comply with the "Technical Specifications for Silt Dams" to ensure the reliability of engineering quality and carbon sink effects [1] Group 2: Market Integration and Future Steps - The silt dam carbon sink methodology is a necessary technical specification to support the inclusion of silt dam carbon sink projects in the national voluntary greenhouse gas emission reduction trading market, laying the foundation for participation in this market [1] - The methodology is expected to attract social capital investment in soil erosion control, further establishing a sound investment cycle mechanism for soil and water conservation [1] - The Yellow River Conservancy Commission will continue to enhance technical guidance and regulatory services, expanding the depth and breadth of carbon sink research in soil and water conservation, thereby injecting strong green momentum into the high-quality development of the Yellow River Basin [1]
