IOANNA FORCE against its type
Built in 2017, it is 5 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 43,231 gross tonnage it is larger than 72% 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 121 other vessels here, 78 of them bulk carriers. Its MRV returns name it SAKIZAYA NOBLE for 2018–2019, KLEISOURA for 2021–2024 and IOANNA FORCE for 2025. The reported port of registry changed: PANAMA (2018–2024), then Majuro (2025).
Its 5,376 t of CO₂ for 2025 is 1.7 times the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 279.8 kg CO₂, close to the type median of 260.7 kg. It logged 1,910 hours at sea against a median of 1,199 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2023 (8,997 t) and the lowest 2018 (1,743 t). Its efficiency percentile within the type went from 19 in 2018 to 47 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,543 of 3,241 qualifying bulk carriers by EEOI, at the 47th percentile. The dashed line is the type median, 7.6; this vessel reported 7.4.
EEOI divides emissions by transport work, which for this vessel and year was 726,481,081 tonne-miles over 19,212 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 208.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2023 to 2025, emissions fell 40.2% while distance sailed fell 47.8%and CO₂ per nautical mile rose 14.4%.That points mainly to how much the vessel sailed, rather than the other.
