TUNA S against its type
Built in 2019, it is 12 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,703 gross tonnage it is larger than 89% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The returns for 2024–2025 all give Monrovia as port of registry.
Its 4,022 t of CO₂ for 2025 is 43% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 159.0 kg CO₂, 30% above the type median of 122.2 kg. It logged 2,405 hours at sea against a median of 3,044 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
