NAVI STAR against its type
Built in 2011, it is 4 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 23,264 gross tonnage it is larger than 88% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 310 general cargo ships here under the Panama flag, 10.1% of the 3,081 on the register. The same builder is recorded for 323 other vessels here, 25 of them general cargo ships. Its MRV returns name it OCEAN BARI-STAR for 2019 and NAVI STAR for 2021–2025. The returns for 2019–2025 all give PANAMA as port of registry.
Its 1,509 t of CO₂ for 2025 is 46% below 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 232.4 kg CO₂, 1.9 times the type median of 122.2 kg. It logged 509 hours at sea against a median of 3,044 hours for its type that year. 2.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2023 (4,929 t) and the lowest 2025 (1,509 t). Its efficiency percentile within the type went from 92 in 2019 to 53 in 2023 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 1,721 of 3,262 qualifying bulk carriers by EEOI, at the 53rd percentile. The dashed line is the type median, 8.0; this vessel reported 8.2.
EEOI divides emissions by transport work, which for this vessel and year was 602,537,897 tonne-miles over 22,507 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 46.8% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 34.2% and CO₂ per nautical mile rose 8.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
