如何精准监测大型燃煤电厂碳排放？中国团队研发出卫星遥感新方案

Core Viewpoint - The article highlights significant advancements in the precise monitoring and accounting of carbon emissions from large coal-fired power plants, which are crucial for achieving global carbon neutrality goals [1][2]. Group 1: Research Breakthroughs - The Chinese Academy of Sciences has achieved a breakthrough in remote sensing and carbon emission estimation, enabling high-precision dynamic quantification and mapping of CO2 emissions from large coal-fired power plants [2]. - The research team developed a new satellite remote sensing approach, marking the first time high-precision dynamic quantification of CO2 emissions from large coal-fired power plants has been realized internationally [2][4]. Group 2: Importance of Carbon Emission Monitoring - Coal-fired power plants account for approximately 50% of global carbon emissions from fossil fuel combustion, making accurate carbon accounting essential for global carbon assessments and the electricity sector [3]. - Traditional methods of calculating emissions rely heavily on self-reported data from power plants, which can lead to discrepancies and lack of comparability due to the absence of unified international accounting standards [3]. Group 3: Methodological Innovations - The research team introduced an innovative optimization algorithm that significantly enhances the efficiency of identifying background carbon emission levels and improves the accuracy of smoke plume trajectory inversion [4]. - The study successfully quantified CO2 emissions from 14 large coal-fired power plants, with emissions ranging from 21.54 thousand tons to 82.3 thousand tons per day, demonstrating a marked improvement in inversion accuracy [4].
