Core Insights - The methane reduction methodology for rice paddies developed by the Shanghai Academy of Agricultural Sciences has been adopted as the 103rd small-scale reduction methodology under the UN Framework Convention on Climate Change's Clean Development Mechanism (CDM) [1] - This methodology is China's first independently developed rice paddy methane reduction methodology with complete intellectual property rights and marks the second such methodology adopted by the CDM [1] - The establishment of this methodology signifies China's international leadership in agricultural greenhouse gas reduction methodologies and its capability to formulate core international rules and standards in this field [1] Summary by Sections Development and Research - Since 2012, the research team has established a long-term experimental base for low-carbon agriculture, conducting long-term monitoring of greenhouse gas emissions and soil carbon sinks under various rice cultivation management models, accumulating hundreds of thousands of data points [1] - The team has systematically developed low-carbon agricultural technologies, including high-yield low-water rice variety selection, optimized water management, precise fertilizer application, comprehensive straw utilization, and innovative crop rotation models [1] Methodology and Standards - The newly developed methodology includes technologies for methane reduction in rice paddies, nitrous oxide suppression in dryland, soil carbon sequestration in farmland, and straw carbonization for reduction and enhancement of carbon sinks [1] - The water-saving drought-resistant rice methane reduction technology is one of the key outcomes, effectively coupling water management and drought-resistant varieties to ensure stable yields while achieving significant methane reduction [2] Economic and Environmental Impact - The "Chinese solution" for rice paddy methane reduction aligns perfectly with the core concept of the Paris Agreement, which advocates for international cooperation to promote sustainable development and reduction benefits [2] - The certified emission reductions generated from projects developed based on this methodology are expected to enter the international carbon trading market, providing low-carbon technologies for rice producers and creating carbon revenue for project developers, thereby stimulating economic drivers for agricultural emissions reduction [2]

Core Viewpoint - The "Methane Emission Reduction Methodology for Rice Fields," developed by the Shanghai Academy of Agricultural Sciences, has been officially adopted as the 103rd small-scale emission reduction methodology under the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change, marking a significant achievement in agricultural greenhouse gas reduction research in China [1][2]. Group 1: Methodology Development - The methodology is China's first independently developed CDM methodology for methane reduction in rice fields, showcasing the country's leading position in this research area and its ability to establish core international rules and standards [1]. - The Shanghai Low Carbon Agricultural Engineering Technology Research Center has been conducting long-term monitoring of greenhouse gas emissions and soil carbon sinks in rice fields since 2012, accumulating hundreds of thousands of observation data points [2]. Group 2: Technological Innovations - The research team has developed various low-carbon agricultural technologies, including high-yield low-emission rice varieties, optimized water management, precise fertilizer application, comprehensive straw utilization, and innovative crop rotation models [2]. - A specific technology utilizing drought-resistant rice varieties has been developed, which effectively reduces methane emissions while maintaining stable yields, making it replicable and easy to promote [3]. Group 3: Global Implications - The adoption of this methodology provides a feasible and operational path for methane reduction, particularly for developing countries facing food security, emission reduction pressures, and water resource shortages [3]. - The certified emission reductions (CERs) generated from projects developed under this methodology are expected to enter broader international carbon trading markets, creating economic incentives for low-carbon rice production and attracting global investment towards sustainable agricultural practices [3].
