CLYMENE: CO₂ emissions 2018–2025

CLYMENE against its type

Built in 2006, it is 6 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 40,244 gross tonnage it is larger than 63% 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 98 other vessels here, 49 of them bulk carriers. Its MRV returns name it CLYMENE for 2018 and NANXIN ANGELA for 2024–2025. The reported port of registry changed: Valletta (2018), then MAJURO (2024–2025).

Its 3,611 t of CO₂ for 2025 is 12% 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 289.4 kg CO₂, 11% above the type median of 260.7 kg. It logged 1,096 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%. Its efficiency percentile within the type went from 58 in 2018 to 44 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 1,424 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 503,645,746 tonne-miles over 12,478 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 36.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, so the series has gaps.

From 2018 to 2025, emissions fell 36.3% while distance sailed fell 27.4%and CO₂ per nautical mile fell 12.2%.That points mainly to how much the vessel sailed, rather than the other.
