NEPTULUS against its type
Built in 2012, it is 5 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 21,229 gross tonnage it is larger than 83% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. The returns for 2019–2025 all give Majuro as port of registry.
Its 2,389 t of CO₂ for 2025 is 15% 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 230.4 kg CO₂, 1.9 times the type median of 122.2 kg. It logged 925 hours at sea against a median of 3,044 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2020 (5,811 t) and the lowest 2024 (2,203 t). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2020
Position 2,405 of 2,985 qualifying bulk carriers by EEOI, at the 81st percentile. The dashed line is the type median, 8.1; this vessel reported 11.2.
EEOI divides emissions by transport work, which for this vessel and year was 520,666,667 tonne-miles over 24,895 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.2% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 8.4% and CO₂ per nautical mile rose 9.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
