LYME BAY against its type
Built in 2013, it is 5 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 196 other vessels here, 17 of them container ships. Its MRV returns name it LYME BAY for 2021–2023 and RDO LIBERTY for 2024–2025. The returns for 2021–2025 all give Monrovia as port of registry.
Its 19,165 t of CO₂ for 2025 is 17% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 557.5 kg CO₂, close to the type median of 545.6 kg. It logged 2,285 hours at sea against a median of 3,155 hours for its type that year. 1.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2023 (24,545 t) and the lowest 2021 (4,999 t). Its efficiency percentile within the type went from 72 in 2021 to 50 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 927 of 1,838 qualifying container ships by EEOI, at the 50th percentile. The dashed line is the type median, 14.2; this vessel reported 14.3.
EEOI divides emissions by transport work, which for this vessel and year was 1,338,311,452 tonne-miles over 34,377 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 283.3% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.4% while distance sailed fell 7.0%and CO₂ per nautical mile rose 2.7%.That points mainly to how much the vessel sailed, rather than the other.
