CONSCIENTIA against its type
Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 48,799 gross tonnage it is larger than 51% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. Its MRV returns name it RHL CONSCIENTIA for 2020, CONSCIENTIA for 2021 and DACHAN BAY EXPRESS for 2022–2025. The returns for 2020–2025 all give Monrovia as port of registry.
Its 34,408 t of CO₂ for 2025 is 2.1 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 495.4 kg CO₂, close to the type median of 545.6 kg. It logged 5,675 hours at sea against a median of 3,155 hours for its type that year. 3.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2025 (34,408 t) and the lowest 2023 (8,519 t). Its efficiency percentile within the type went from 69 in 2022 to 58 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,066 of 1,838 qualifying container ships by EEOI, at the 58th percentile. The dashed line is the type median, 14.2; this vessel reported 16.5.
EEOI divides emissions by transport work, which for this vessel and year was 2,089,160,899 tonne-miles over 69,455 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.9% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 44.2% while distance sailed rose 42.4%and CO₂ per nautical mile rose 1.2%.That points mainly to how much the vessel sailed, rather than the other.
