MUROVDAG against its type
Built in 2020, it is 13 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 23,770 gross tonnage it is larger than 90% 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. Its MRV returns name it PERSEUS HARMONY for 2021–2023 and MUROVDAG for 2025. The reported port of registry changed: MONROVIA (2021–2023), then MAJURO (2025).
Its 2,502 t of CO₂ for 2025 is 11% 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 253.6 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 969 hours at sea against a median of 3,044 hours for its type that year. 4.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2025 (2,502 t) and the lowest 2021 (1,429 t). Its efficiency percentile within the type went from 16 in 2021 to 48 in 2023 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 1,577 of 3,262 qualifying bulk carriers by EEOI, at the 48th percentile. The dashed line is the type median, 8.0; this vessel reported 7.8.
EEOI divides emissions by transport work, which for this vessel and year was 289,978,344 tonne-miles over 10,655 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 75.0% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 9.9% and CO₂ per nautical mile rose 18.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
