2024年我国碳排放总量增幅低于全球

Core Insights - The "China Greenhouse Gas Bulletin (2024)" indicates that China's anthropogenic carbon emissions are projected to increase by approximately 0.6% in 2024 compared to 2023, a significant reduction in growth rate compared to the 2023 increase, and lower than the global increase of 0.8%, demonstrating China's effective commitment to carbon reduction [1][2] Group 1 - The bulletin has been published for the 14th consecutive year, aimed at supporting national efforts to address climate change and achieve "dual carbon" goals, aligning with the global bulletin released by the World Meteorological Organization (WMO) [1] - The WMO's latest data shows that the global average concentration of carbon dioxide reached 423.9 ppm in 2024, an increase of 3.5 ppm from 2023, marking the largest increase since the establishment of modern observation systems in 1957 [1] - Methane and nitrous oxide concentrations globally reached 1942 ppb and 338 ppb respectively, with the increase attributed to rising fossil fuel emissions, weakened carbon sink capacity under extreme heat, and frequent wildfires [1] Group 2 - The average concentration of carbon dioxide at the Wari Pass station in 2024 is reported at 424.9 ppm, reflecting a 3.5 ppm increase from 2023, consistent with global trends; methane and nitrous oxide concentrations are slightly above global averages at 2003 ppb and 338.4 ppb respectively [2] - The China Meteorological Administration has established a comprehensive greenhouse gas monitoring network since the 1990s, which includes the Wari Pass WMO global background station, seven regional background stations, eleven pilot stations, and over 120 monitoring stations, with data quality recognized internationally [2] - The administration plans to further optimize the layout of greenhouse gas observation stations, enhance high-precision atmospheric monitoring and dynamic analysis, improve carbon accounting capabilities, and deepen research on the impacts and feedback of greenhouse gases on weather and climate, providing robust scientific support for China's climate change response [2]
