MARAN UNITY against its type
Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 93,464 gross tonnage it is larger than 95% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 107 bulk carriers here under the Greece flag, 1.3% of the 8,138 on the register. The same builder is recorded for 196 other vessels here, 94 of them bulk carriers. The returns for 2018–2024 all give Piraeus as port of registry.
Its 6,903 t of CO₂ for 2024 is 2.0 times the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 507.9 kg CO₂, 1.9 times the type median of 264.0 kg. It logged 1,675 hours at sea against a median of 1,238 hours for its type that year. 3.2% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 4 years with reported emissions, the highest was 2022 (9,383 t) and the lowest 2019 (2,929 t). Its efficiency percentile within the type went from 7 in 2018 to 17 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 476 of 2,858 qualifying bulk carriers by EEOI, at the 17th percentile. The dashed line is the type median, 7.9; this vessel reported 5.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,271,215,470 tonne-miles over 13,591 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 53.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2023, so the series has gaps.
From 2022 to 2024, emissions fell 26.4% while distance sailed fell 27.4%and CO₂ per nautical mile rose 1.3%.That points mainly to how much the vessel sailed, rather than the other.
