CS JENNA against its type
Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 23,269 gross tonnage it is smaller than 82% 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 same builder is recorded for 323 other vessels here, 238 of them bulk carriers. The returns for 2018–2025 all give MAJURO as port of registry.
Its 5,569 t of CO₂ for 2024 is 1.6 times the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 225.4 kg CO₂, 15% below the type median of 264.0 kg. It logged 2,247 hours at sea against a median of 1,238 hours for its type that year. 6.2% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 6 years with reported emissions, the highest was 2024 (5,569 t) and the lowest 2021 (1,698 t). Its efficiency percentile within the type went from 42 in 2018 to 69 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 3 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 1,977 of 2,858 qualifying bulk carriers by EEOI, at the 69th percentile. The dashed line is the type median, 7.9; this vessel reported 9.6.
EEOI divides emissions by transport work, which for this vessel and year was 581,960,293 tonne-miles over 24,707 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 2.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2023 to 2024, emissions rose 138.9% while distance sailed rose 91.5%and CO₂ per nautical mile rose 24.8%.That points mainly to how much the vessel sailed, rather than the other.
