IOANNA D 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). At 22,434 gross tonnage it is smaller than 85% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The returns for 2018–2025 all give Monrovia as port of registry.
Its 4,974 t of CO₂ for 2025 is 1.5 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 245.3 kg CO₂, close to the type median of 260.7 kg. It logged 1,909 hours at sea against a median of 1,200 hours for its type that year. 2.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2019 (7,844 t) and the lowest 2020 (913 t). Its efficiency percentile within the type went from 87 in 2018 to 81 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,620 of 3,241 qualifying bulk carriers by EEOI, at the 81st percentile. The dashed line is the type median, 7.6; this vessel reported 10.6.
EEOI divides emissions by transport work, which for this vessel and year was 470,175,803 tonne-miles over 20,281 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 17.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 65.6% while distance sailed rose 72.3%and CO₂ per nautical mile fell 3.9%.That points mainly to how much the vessel sailed, rather than the other.
