Abstract: Inland water vessels are a substantial but poorly quantified source of transport-sector CO2 emissions. Using approximately 20 billion automatic identification system records and a trajectory completion algorithm, we provide a global high-resolution assessment of inland vessel CO2 emissions. These vessels emitted 164.0 ± 1.58 TgCO2 in 2022, equivalent to 24.7% of global waterborne vessel emissions, despite operating on only 0.4% of the global navigable marine and inland water surface area. Emissions are concentrated within a few hotspot river corridors and exhibit baseline-dependent amplification (2019–2022) together with seasonal variability. These patterns reflect the combined effects of transport demand and hydroclimatic constraints on navigability. Because inland water vessel emissions occur within river corridors where riverine CO2 evasion is also active, they represent an important anthropogenic carbon source and may influence river–atmosphere CO2 exchange. These results provide a basis for improving inland transport emission inventories and informing targeted mitigation strategies under climate change.
摘要:内河船舶是交通运输业CO2排放的重要来源,但其排放量却很低。利用约200亿条自动识别系统记录和轨迹补全算法,我们提供了一个全球高分辨率的内河船舶二氧化碳排放评估。这些船只共排放164±1.58 Tg CO2,相当于2022年的24.7 %的全球水上船舶排放,尽管仅占全球通航海洋和内陆水面面积的0.4 %。排放集中在少数热点河流廊道内,并表现出与基线相关的放大效应( 2019 - 2022年 )和季节变化。这些模式反映了运输需求和水文气候限制对通航能力的综合影响。 由于内河船舶排放发生在河流廊道内,河流的CO2逃逸也很活跃,因此它们是重要的人为碳源,并可能影响河流-大气CO2交换。这些结果为完善内陆运输排放清单和制定气候变化下有针对性的减排策略提供了依据。
