The Danube navigation is geographically limited and subject to the effects of environmental change. On the other hand, the Danube commercial navigation is the point source of pollution with emissions of the Danube vessels and harbours, directly polluting the environment. The focus of this paper is the annual evaluation and calculation of air polluting emissions from fossil fuel consumption from the following types of the Danube fleet: push boats, pull boats, freight motor vessels and cruise passenger ships. Emissions from the Danube transport vessels are estimated by EMEP/EEA (European Monitoring and Evaluation Programme/European Environment Agency) air pollutant emission inventory guidebook within Serbian-Croatian, Serbian and Serbian-Romanian sections of the Danube fairway on an average level. Emissions costs for all types of the Danube fleet (euro per vessel-kilometre) are estimated by the Practical guideline for realistic transport pricing depending on the population density close to the waterway: rural or urban area.

多瑙河航行在地理上受到限制，并受到环境变化的影响。另一方面，多瑙河商业航行是点源污染，多瑙河船舶和港口的排放物直接污染环境。本文的重点是对以下类型的多瑙河船队的化石燃料消耗造成的空气污染排放进行年度评估和计算：推船、拖船、货运机动船和游轮。多瑙河运输船的排放量是根据 EMEP/EEA（欧洲监测和评估计划/欧洲环境署）空气污染物排放清单指南在多瑙河航道的塞尔维亚-克罗地亚、塞尔维亚和塞尔维亚-罗马尼亚路段估算的平均水平。
