ESMERALDA against its type
Built in 2009, it is 3 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 31,236 gross tonnage it is smaller than 68% 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 83 other vessels here, 71 of them bulk carriers. The returns for 2023–2025 all give MAJURO as port of registry.
Its 2,551 t of CO₂ for 2025 is 21% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 232.7 kg CO₂, 11% below the type median of 260.7 kg. It logged 810 hours at sea against a median of 1,200 hours for its type that year. 5.6% 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 (2,551 t) and the lowest 2024 (1,373 t). Its efficiency percentile within the type went from 67 in 2023 to 77 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 2,489 of 3,241 qualifying bulk carriers by EEOI, at the 77th percentile. The dashed line is the type median, 7.6; this vessel reported 10.0.
EEOI divides emissions by transport work, which for this vessel and year was 256,150,602 tonne-miles over 10,966 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.9% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 85.8% and CO₂ per nautical mile fell 22.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
