DSI POLARIS against its type
Built in 2018, it is 6 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 34,547 gross tonnage it is smaller than 53% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 83 other vessels here, 71 of them bulk carriers. Its MRV returns name it STH OSLO for 2020–2021 and DSI POLARIS for 2024–2025. The returns for 2020–2025 all give Majuro as port of registry.
Its 3,258 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 261.4 kg CO₂, close to the type median of 260.7 kg. It logged 1,092 hours at sea against a median of 1,200 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2024 (3,545 t) and the lowest 2020 (1,186 t). Its efficiency percentile within the type went from 40 in 2020 to 44 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,428 of 3,241 qualifying bulk carriers by EEOI, at the 44th percentile. The dashed line is the type median, 7.6; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 454,362,622 tonne-miles over 12,461 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 174.6% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 8.1% while distance sailed fell 17.7%and CO₂ per nautical mile rose 11.6%.That points mainly to how much the vessel sailed, rather than the other.
