This dataset represents the provision of one ton-kilometer transportation service by inland liquid cargo ships within inland waterway areas (regardless of watershed). The transportation dataset covers the entire life cycle, including the production and maintenance of liquid cargo ships, the construction of canals and ports, as well as energy use and operational emissions. The proportion of transportation services for liquid cargo ships of various deadweight tonnages is reasonably extrapolated based on relevant nationwide data on inland liquid cargo ship deadweight tonnage and freight turnover, literature, and other sources.
