DIAMOND SKY against its type
Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 31,617 gross tonnage it is smaller than 67% 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 24 other vessels here, 16 of them bulk carriers. The returns for 2018–2025 all give Valletta as port of registry.
Its 1,279 t of CO₂ for 2023 is 62% below the median of 3,386 t among the 3,573 bulk carriers on this register that reported for 2023. Per nautical mile it emitted 280.8 kg CO₂, close to the type median of 272.6 kg. It logged 402 hours at sea against a median of 1,186 hours for its type that year. 4.9% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Across 4 years with reported emissions, the highest was 2019 (3,712 t) and the lowest 2023 (1,279 t). Its efficiency percentile within the type went from 78 in 2018 to 46 in 2023 (lower is more efficient).
No EU/EEA voyages were reported for 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2023
Position 1,490 of 3,262 qualifying bulk carriers by EEOI, at the 46th percentile. The dashed line is the type median, 8.0; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 167,388,744 tonne-miles over 4,554 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 47.9% lower than in 2018, for EU/EEA voyages only.
From 2022 to 2023, emissions fell 63.6% while distance sailed fell 63.5%and CO₂ per nautical mile fell 0.4%.That points mainly to how much the vessel sailed, rather than the other.
