我国人为碳排放总量增幅显著收窄

Core Viewpoint - China's carbon emissions are projected to increase by approximately 0.6% in 2024 compared to 2023, indicating a significant reduction in the growth rate and remaining below the global increase of 0.8%, demonstrating the effectiveness of China's carbon reduction commitments [1][2] Group 1: China's Greenhouse Gas Monitoring - The China Meteorological Administration has released the "China Greenhouse Gas Bulletin (2024)", marking the 14th consecutive year of monitoring greenhouse gas emissions in the country [1] - China has established a national atmospheric background greenhouse gas observation network consisting of one global background station, 18 regional background stations, and over 120 greenhouse gas observation stations [1] Group 2: Carbon Dioxide Concentration Trends - In 2024, the annual average concentration of carbon dioxide at the Wali Guan station is expected to rise to 424.9 ppm, an increase of 3.5 ppm from 2023, aligning with the global average increase [1] - Regional background stations in China have observed an upward trend in annual average concentrations of carbon dioxide and methane compared to 2023, with specific stations showing increases below the global average [1] Group 3: Global Greenhouse Gas Trends - The World Meteorological Organization reported that the global average concentration of carbon dioxide reached 423.9 ppm in 2024, marking the largest annual increase since modern observations began in 1957 [2] - The increase in global greenhouse gas concentrations is attributed to rising emissions from fossil fuel combustion, weakened carbon sink capacity due to extreme temperatures, and increased carbon emissions from wildfires in 2024 [2] Group 4: Future Monitoring and Research - The China Meteorological Administration plans to optimize the layout of greenhouse gas observation stations, enhance high-precision monitoring and dynamic analysis, improve carbon accounting capabilities, and deepen research on the impacts of greenhouse gases on weather and climate [2]
