MALTEZA against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 31,250 gross tonnage it is smaller than 68% 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 83 other vessels here, 71 of them bulk carriers. Its MRV returns name it TRITON SWALLOW for 2019 and MALTEZA for 2023–2025. The reported port of registry changed: Panama (2019), then VALLETTA (2023), then VALETTA (2024–2025).
Its 6,784 t of CO₂ for 2025 is 2.1 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 361.7 kg CO₂, 39% above the type median of 260.7 kg. It logged 1,720 hours at sea against a median of 1,200 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2025 (6,784 t) and the lowest 2024 (831 t). Its efficiency percentile within the type went from 49 in 2019 to 74 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 2,417 of 3,241 qualifying bulk carriers by EEOI, at the 74th percentile. The dashed line is the type median, 7.6; this vessel reported 9.7.
EEOI divides emissions by transport work, which for this vessel and year was 701,585,315 tonne-miles over 18,755 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 236.4% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 716.0% while distance sailed rose 567.0%and CO₂ per nautical mile rose 22.3%.That points mainly to how much the vessel sailed, rather than the other.
