中国气象局：我国积极履行碳减排承诺已取得实际成效

Core Insights - The global near-surface concentrations of the three main greenhouse gases continue to rise, with China's carbon emissions projected to increase by approximately 0.6% in 2024 compared to 2023, which is a significant reduction from the previous year's growth rate of 0.8% [1][2] - The China Meteorological Administration (CMA) released the "China Greenhouse Gas Bulletin (2024)", marking the 14th consecutive year of monitoring greenhouse gas emissions in China [1][3] Group 1: Greenhouse Gas Emissions - In 2024, the average concentration of carbon dioxide (CO2) reached 423.9 ppm, an increase of 3.5 ppm from 2023, marking the largest annual increase since modern observations began in 1957 [1][2] - Methane and nitrous oxide concentrations were recorded at 1942 ppb and 338 ppb, respectively, indicating a continuing upward trend in greenhouse gas levels globally [1][2] Group 2: China's Monitoring Efforts - The CMA has established a national atmospheric greenhouse gas observation network, which includes one WMO global baseline station, seven regional baseline stations, and over 120 greenhouse gas observation stations [3][5] - The Wali Guan National Atmospheric Baseline Station is the only station in China included in the WMO Global Atmosphere Watch program, providing critical data for the WMO Global Greenhouse Gas Bulletin [3][5] Group 3: Future Directions - The CMA aims to enhance its capabilities in greenhouse gas monitoring, assessment, and carbon source-sink accounting, with plans to optimize the observation network and improve high-precision monitoring and dynamic analysis [6]
