AMIS WISDOM III against its type
It is one of 428 bulk carriers here under the Singapore flag, 5.3% of the 8,138 on the register. Its MRV returns name it AMIS WISDOM III for 2020–2024 and WW HANNA for 2025. The reported port of registry changed: PANAMA (2020–2024), then Singapore (2025).
Its 4,026 t of CO₂ for 2025 is 24% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 290.9 kg CO₂, 12% above the type median of 260.7 kg. It logged 1,427 hours at sea against a median of 1,200 hours for its type that year. 0.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2025 (4,026 t) and the lowest 2020 (2,241 t). Its efficiency percentile within the type went from 46 in 2020 to 14 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 455 of 3,241 qualifying bulk carriers by EEOI, at the 14th percentile. The dashed line is the type median, 7.6; this vessel reported 5.1.
EEOI divides emissions by transport work, which for this vessel and year was 789,325,490 tonne-miles over 13,837 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 79.7% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 16.2% while distance sailed fell 3.5%and CO₂ per nautical mile rose 20.4%.That points mainly to how efficiently it sailed, rather than the other.
