POLARIS Z against its type
Built in 1995, it is 17 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 11,176 gross tonnage it is smaller than 98% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 5 bulk carriers here under the Comoros flag, 0.1% of the 8,138 on the register. The same builder is recorded for 95 other vessels here, 64 of them bulk carriers. The returns for 2024–2025 all give Moroni as port of registry.
Its 2,518 t of CO₂ for 2025 is 22% 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 172.0 kg CO₂, 34% below the type median of 260.7 kg. It logged 1,352 hours at sea against a median of 1,200 hours for its type that year. 4.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 2,605 of 2,858 qualifying bulk carriers by EEOI, at the 91st percentile. The dashed line is the type median, 7.9; this vessel reported 13.9.
EEOI divides emissions by transport work, which for this vessel and year was 84,070,504 tonne-miles over 8,741 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 115.5% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 115.5% and CO₂ per nautical mile rose 28.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
