SN SERENITY against its type
Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 22,426 gross tonnage it is smaller than 85% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 26 bulk carriers here under the South Korea flag, 0.3% of the 8,138 on the register. The same builder is recorded for 95 other vessels here, 64 of them bulk carriers. The returns for 2023–2025 all give JEJU as port of registry.
Its 4,085 t of CO₂ for 2025 is 26% 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 178.0 kg CO₂, 32% below the type median of 260.7 kg. It logged 2,024 hours at sea against a median of 1,200 hours for its type that year. 3.5% 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 (4,085 t) and the lowest 2023 (424 t). Its efficiency percentile within the type went from 70 in 2024 to 38 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,247 of 3,241 qualifying bulk carriers by EEOI, at the 38th percentile. The dashed line is the type median, 7.6; this vessel reported 6.8.
EEOI divides emissions by transport work, which for this vessel and year was 599,023,460 tonne-miles over 22,950 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 864.4% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 18.5% while distance sailed rose 27.4%and CO₂ per nautical mile fell 7.0%.That points mainly to how much the vessel sailed, rather than the other.
