RUBY against its type
Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,760 gross tonnage it is larger than 90% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 69 general cargo ships here under the Malta flag, 2.2% of the 3,081 on the register. The same builder is recorded for 983 other vessels here, 22 of them general cargo ships. The reported port of registry changed: Valetta (2021), then Valletta (2022–2025).
Its 710 t of CO₂ for 2024 is 82% below the median of 4,046 t among the 1,395 general cargo ships on this register that reported for 2024. Per nautical mile it emitted 256.1 kg CO₂, 37% above the type median of 187.0 kg. It logged 221 hours at sea against a median of 2,074 hours for its type that year. 7.4% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 4 years with reported emissions, the highest was 2021 (7,889 t) and the lowest 2024 (710 t). Of the 3 sister ships listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2021
Position 1,692 of 3,276 qualifying bulk carriers by EEOI, at the 52nd percentile. The dashed line is the type median, 8.4; this vessel reported 8.5.
EEOI divides emissions by transport work, which for this vessel and year was 928,117,647 tonne-miles over 32,488 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 91.0% lower than in 2021, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 62.2% and CO₂ per nautical mile rose 17.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
