DEVBULK DENIZ 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 25,427 gross tonnage it is larger than 92% 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. Maestro Shipping is linked to 2 vessels on this register. Its MRV returns name it MAESTRO EMERALD for 2021–2023 and DEVBULK DENIZ for 2024–2025. The returns for 2021–2025 all give Majuro as port of registry.
Its 2,788 t of CO₂ for 2025 is close to 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 180.2 kg CO₂, 47% above the type median of 122.2 kg. It logged 1,513 hours at sea against a median of 3,044 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2023 (6,627 t) and the lowest 2025 (2,788 t). Its efficiency percentile within the type went from 47 in 2021 to 80 in 2023 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 2,595 of 3,262 qualifying bulk carriers by EEOI, at the 80th percentile. The dashed line is the type median, 8.0; this vessel reported 11.2.
EEOI divides emissions by transport work, which for this vessel and year was 590,147,818 tonne-miles over 30,522 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.5% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 49.0% and CO₂ per nautical mile fell 4.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
