People.cn (SH:603000) Shui Li Bu Wang Zhan·2025-12-24 08:44Core Viewpoint - The Ministry of Ecology and Environment and the Ministry of Water Resources in China have jointly released the "Greenhouse Gas Voluntary Emission Reduction Project Methodology: Sediment Dams," which introduces a calculation method for certified voluntary emission reductions, marking an international first in this area [1][2]. Group 1: Background and Significance - The "14th Five-Year Plan" emphasizes the integration of comprehensive soil erosion control into carbon sink capacity enhancement actions, highlighting the importance of sediment dams as a unique water and soil conservation engineering measure in China [1]. - Sediment dams are effective in intercepting sediment, preserving soil carbon, and reducing the mineralization of organic carbon in soil, thus providing favorable conditions for plant growth and contributing to carbon sequestration [1]. Group 2: Methodology Details - The methodology serves as the main guideline for the design, implementation, approval, and verification of greenhouse gas voluntary emission reduction projects, ensuring scientific, operable, and conservative principles [2]. - Key components of the sediment dam carbon sink methodology include applicable conditions, project boundaries, accounting periods, and carbon pool selection, with a minimum accounting period of 10 years and a maximum of 40 years [2]. Group 3: Future Directions - The Ministry of Water Resources plans to expand the coverage of the national carbon emission trading market and accelerate the construction of the voluntary greenhouse gas emission reduction trading market [2]. - There will be increased promotion and support for eligible sediment dam carbon sink projects, encouraging participation in the national voluntary emission reduction trading market to generate revenue for new sediment dam construction [2].
