This dataset represents the provision of 1 ton of transportation service over a distance of 1 kilometer by a dry cargo vessel (deadweight of 4,000 tons) in inland waterway regions (regardless of watershed). The transportation dataset covers the entire life cycle, including the production and maintenance of the dry cargo vessel, the construction of canals and ports, and energy consumption and operational emissions.
The dry cargo vessel has a DWT (deadweight tonnage) of 4,000 tons and a main engine power of approximately 1,100 kW, both values based on Chinese inland vessel standards. Fuel consumption is calculated based on the vessel's load capacity, main engine power, and operational speed. Major emissions (CO2, NOx, SOx, PM, NMVOC, CO, CH4, N2O, etc.) are calculated according to inland waterway vessel fuel consumption and relevant standards. For port and canal infrastructure, data is reasonably extrapolated based on global port and canal information.
