DEVBULK DEMET 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). 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 LADY DEMET for 2018–2021 and DEVBULK DEMET for 2024–2025. The returns for 2018–2025 all give MAJURO as port of registry.
Its 6,689 t of CO₂ for 2025 is 2.4 times 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 171.4 kg CO₂, 40% above the type median of 122.2 kg. It logged 4,040 hours at sea against a median of 3,044 hours for its type that year. 4.0% 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 2020 (8,632 t) and the lowest 2021 (2,477 t). Its efficiency percentile within the type went from 99 in 2018 to 85 in 2021 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021
Position 2,797 of 3,276 qualifying bulk carriers by EEOI, at the 85th percentile. The dashed line is the type median, 8.4; this vessel reported 12.5.
EEOI divides emissions by transport work, which for this vessel and year was 198,450,320 tonne-miles over 10,450 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 78.1% and CO₂ per nautical mile rose 4.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
