SM HARMONY1 against its type
Built in 2020, it is 8 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 43,989 gross tonnage it is larger than 75% 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 reported port of registry changed: NAJURO (2020–2021), then MAJURO (2022–2025).
Its 6,358 t of CO₂ for 2025 is 2.0 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 290.5 kg CO₂, 11% above the type median of 260.7 kg. It logged 2,194 hours at sea against a median of 1,200 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2020 (8,894 t) and the lowest 2021 (1,601 t). Its efficiency percentile within the type went from 19 in 2020 to 18 in 2025 (lower is more efficient). Of the 6 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 587 of 3,241 qualifying bulk carriers by EEOI, at the 18th percentile. The dashed line is the type median, 7.6; this vessel reported 5.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,173,062,731 tonne-miles over 21,888 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.5% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 69.2% while distance sailed rose 89.2%and CO₂ per nautical mile fell 10.6%.That points mainly to how much the vessel sailed, rather than the other.
