NAOMI 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 94,351 gross tonnage it is larger than 96% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 479 bulk carriers here under the Malta flag, 5.9% of the 8,138 on the register. The same builder is recorded for 194 other vessels here, 124 of them bulk carriers. Thome Ship Management is linked to 42 vessels on this register. Its MRV returns name it STELLA NAOMI for 2018 and NAOMI for 2021–2025. The returns for 2021–2025 all give Valletta as port of registry.
Its 4,146 t of CO₂ for 2025 is 28% 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 510.5 kg CO₂, 2.0 times the type median of 260.7 kg. It logged 803 hours at sea against a median of 1,200 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2018 (14,171 t) and the lowest 2025 (4,146 t). Its efficiency percentile within the type went from 10 in 2018 to 23 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 751 of 3,241 qualifying bulk carriers by EEOI, at the 23rd percentile. The dashed line is the type median, 7.6; this vessel reported 5.8.
Across the 39 ranked vessels operated by Thome Ship Management, the median percentile is 54. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 714,837,931 tonne-miles over 8,122 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 70.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 16.9% while distance sailed fell 13.1%and CO₂ per nautical mile fell 4.3%.That points mainly to how much the vessel sailed, rather than the other.
