MARIETTA against its type
Built in 2004, it is 8 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 40,135 gross tonnage it is larger than 62% 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 660 other vessels here, 60 of them bulk carriers. Its MRV returns name it MARIETTA for 2019–2023 and MARIETTA C for 2024–2025. The returns for 2019–2025 all give Valletta as port of registry.
Its 3,553 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 279.2 kg CO₂, close to the type median of 260.7 kg. It logged 1,119 hours at sea against a median of 1,200 hours for its type that year. 3.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2021 (9,411 t) and the lowest 2023 (2,632 t). Its efficiency percentile within the type went from 93 in 2019 to 77 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 2,497 of 3,241 qualifying bulk carriers by EEOI, at the 77th percentile. The dashed line is the type median, 7.6; this vessel reported 10.0.
EEOI divides emissions by transport work, which for this vessel and year was 355,253,000 tonne-miles over 12,724 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 20.4% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 59.8% while distance sailed fell 58.3%and CO₂ per nautical mile fell 3.5%.That points mainly to how much the vessel sailed, rather than the other.
