我国碳减排承诺取得实效！中国气象局：人为碳排放增速低于全球

Core Insights - The report indicates that China's anthropogenic carbon emissions are projected to increase by approximately 0.6% in 2024 compared to 2023, which is a significant reduction in growth rate compared to the 0.8% global increase, demonstrating China's commitment to carbon reduction is yielding tangible results [1] Group 1: Greenhouse Gas Monitoring - The China Meteorological Administration (CMA) has established a national atmospheric background greenhouse gas observation network, which includes one WMO global background station, seven regional background stations, eleven trial background stations, and over 120 greenhouse gas observation stations [1] - The CMA's greenhouse gas observation methods, standards, and processes are aligned with international practices, ensuring data quality and international comparability [1][3] Group 2: Atmospheric Background Station Data - The Wariwan National Atmospheric Background Station, the only station in China included in the WMO Global Atmospheric Observation Program (GAW), reported that the annual average concentration of carbon dioxide in 2024 reached 424.9 ppm, an increase of 3.5 ppm from 2023, which is consistent with the global average [2] - Methane and nitrous oxide annual average concentrations were recorded at 2003 ppb and 338.4 ppb, respectively, slightly above global averages [2] Group 3: Future Developments - The CMA aims to enhance its capabilities in greenhouse gas monitoring, assessment, measurement standards, and carbon source-sink accounting, with plans to optimize the observation station network and improve high-precision atmospheric greenhouse gas monitoring and dynamic analysis [3]
