TSUKUYOMI ETERNITY 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 TSUKUYOMI HARMONY for 2021 and TSUKUYOMI ETERNITY for 2022–2025. The reported port of registry changed: Monrovia (2021), then SINGAPORE (2022–2023).
Its 4,732 t of CO₂ for 2025 is 46% above the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 208.1 kg CO₂, 20% below the type median of 260.7 kg. It logged 2,152 hours at sea against a median of 1,199 hours for its type that year. 3.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2025 (4,732 t) and the lowest 2022 (1,920 t). Its efficiency percentile within the type went from 52 in 2021 to 44 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,445 of 3,241 qualifying bulk carriers by EEOI, at the 44th percentile. The dashed line is the type median, 7.6; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 658,121,001 tonne-miles over 22,734 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 86.4% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 90.3% while distance sailed rose 69.9%and CO₂ per nautical mile rose 12.0%.That points mainly to how much the vessel sailed, rather than the other.
