0540 STAR SKY against its type
Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 42,604 gross tonnage it is larger than 67% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The same builder is recorded for 38 other vessels here, 23 of them bulk carriers. Its MRV returns name it 0540 STAR SKY for 2021 and STAR SKY for 2024–2025. The reported port of registry changed: Georgetown, Grand Cayman (2021), then Monrovia (2024–2025).
Its 4,033 t of CO₂ for 2025 is 25% 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 298.1 kg CO₂, 14% above the type median of 260.7 kg. It logged 1,362 hours at sea against a median of 1,200 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2021 (5,935 t) and the lowest 2024 (3,151 t). Its efficiency percentile within the type went from 61 in 2021 to 25 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 799 of 3,241 qualifying bulk carriers by EEOI, at the 25th percentile. The dashed line is the type median, 7.6; this vessel reported 5.9.
EEOI divides emissions by transport work, which for this vessel and year was 682,470,389 tonne-miles over 13,528 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 32.0% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 28.0% while distance sailed rose 40.5%and CO₂ per nautical mile fell 8.9%.That points mainly to how much the vessel sailed, rather than the other.
