温室气体公报显示 我国人为碳排放总量增幅显著收窄

Core Insights - The report indicates that China's anthropogenic carbon emissions are projected to increase by approximately 0.6% in 2024 compared to 2023, a significant reduction from the previous year's growth rate, and lower than the global increase of 0.8%, demonstrating China's commitment to carbon reduction efforts [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, which includes one global background station recognized by the World Meteorological Organization (WMO), 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 reported to rise to 424.9 ppm, an increase of 3.5 ppm from 2023, aligning with the global average increase [1] - Regional atmospheric background stations in China have observed an upward trend in the 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's report indicates that the global near-surface concentrations of carbon dioxide, methane, and nitrous oxide continue to rise, with carbon dioxide reaching an average concentration of 423.9 ppm, marking the largest annual increase since modern observations began in 1957 [2] - The increase in global greenhouse gas levels is attributed to rising anthropogenic carbon emissions from fossil fuel combustion, weakened carbon sink capabilities of terrestrial and marine ecosystems under extreme heat, 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 atmospheric greenhouse gas monitoring and dynamic analysis, improve carbon accounting capabilities, and deepen research on the impacts and feedback of greenhouse gases on weather and climate [2]
