BLUE CIMENT 4 against its type
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. Its MRV returns name it UBC CHILE for 2019–2022 and BLUE CIMENT 4 for 2023–2025. The reported port of registry changed: Limassol (2019–2020), then Monrovia (2021–2025).
Its 5,339 t of CO₂ for 2025 is close to 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 191.8 kg CO₂, 17% below the type median of 231.1 kg. It logged 2,918 hours at sea against a median of 2,231 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 7 years with reported emissions, the highest was 2022 (12,698 t) and the lowest 2021 (4,616 t). Its efficiency percentile within the type went from 100 in 2019 to 8 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 10 of 119 qualifying other ship typess by EEOI, at the 8th percentile. The dashed line is the type median, 69.3; this vessel reported 24.7.
EEOI divides emissions by transport work, which for this vessel and year was 215,993,123 tonne-miles over 27,837 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 0.8% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 20.8% and CO₂ per nautical mile rose 5.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
