RED ZED I against its type
Built in 2015, it is 6 years newer than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 37,071 gross tonnage it is larger than 89% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 35 vessels in the other ship types category here under the Liberia flag, 7.0% of the 499 on the register. The returns for 2021–2025 all give Monrovia as port of registry.
Its 9,593 t of CO₂ for 2025 is 1.9 times the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 486.2 kg CO₂, 2.1 times the type median of 231.1 kg. It logged 2,660 hours at sea against a median of 2,231 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 3 years with reported emissions, the highest was 2024 (16,173 t) and the lowest 2021 (2,938 t). Its efficiency percentile within the type went from 43 in 2024 to 24 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 29 of 119 qualifying other ship typess by EEOI, at the 24th percentile. The dashed line is the type median, 69.3; this vessel reported 38.0.
EEOI divides emissions by transport work, which for this vessel and year was 252,511,187 tonne-miles over 19,730 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 226.6% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 40.7% while distance sailed fell 45.7%and CO₂ per nautical mile rose 9.3%.That points mainly to how much the vessel sailed, rather than the other.
