This dataset represents the provision of 1 ton-kilometer freight transport service by tankers within coastal/marine areas. The transport dataset covers the entire life cycle of transportation, including tanker production and maintenance, port construction, and energy use and operational emissions. The share of transportation services for tankers of various deadweight tonnages is reasonably extrapolated based on relevant national data on coastal/marine tanker deadweight tonnage and freight turnover, as well as literature and references.
