MDS ARIADNE: CO₂ emissions 2018–2025

MDS ARIADNE against its type

Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). 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 180 other vessels here, 74 of them bulk carriers. Its MRV returns name it TATE J for 2018–2024 and MDS ARIADNE for 2025. The returns for 2018–2025 all give Majuro as port of registry.

Its 5,106 t of CO₂ for 2025 is 1.6 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 242.2 kg CO₂, close to the type median of 260.7 kg. It logged 1,951 hours at sea against a median of 1,200 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2025 (5,106 t) and the lowest 2019 (2,246 t). Its efficiency percentile within the type went from 82 in 2019 to 74 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,390 of 3,241 qualifying bulk carriers by EEOI, at the 74th percentile. The dashed line is the type median, 7.6; this vessel reported 9.6.

EEOI divides emissions by transport work, which for this vessel and year was 534,623,037 tonne-miles over 21,079 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 127.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions rose 92.7% while distance sailed rose 116.9%and CO₂ per nautical mile fell 11.1%.That points mainly to how much the vessel sailed, rather than the other.
