ALAM SEJAHTERA 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 21,183 gross tonnage it is smaller than 88% 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. Its MRV returns name it ALAM SEJAHTERA for 2018–2019 and LENA for 2022–2025. The reported port of registry changed: Singapore (2019), then Majuro (2022–2025).
Its 7,534 t of CO₂ for 2025 is 2.3 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 246.0 kg CO₂, close to the type median of 260.7 kg. It logged 2,937 hours at sea against a median of 1,200 hours for its type that year. 7.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2025 (7,534 t) and the lowest 2018 (2,560 t). Its efficiency percentile within the type went from 32 in 2018 to 78 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,536 of 3,241 qualifying bulk carriers by EEOI, at the 78th percentile. The dashed line is the type median, 7.6; this vessel reported 10.2.
EEOI divides emissions by transport work, which for this vessel and year was 740,758,112 tonne-miles over 30,623 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 194.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 192.2% while distance sailed rose 160.8%and CO₂ per nautical mile rose 12.0%.That points mainly to how much the vessel sailed, rather than the other.
