EPAMINONDAS: CO₂ emissions 2018–2025

EPAMINONDAS against its type

Built in 1998, it is 10 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 80,942 gross tonnage it is larger than 67% 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. The same builder is recorded for 11 other vessels here, 7 of them container ships. Its MRV returns name it MAERSK KALMAR for 2018–2022 and EPAMINONDAS for 2023–2025. The reported port of registry changed: Rotterdam (2018–2019), then Monrovia (2021–2025).

Its 13,578 t of CO₂ for 2025 is 17% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 743.0 kg CO₂, 36% above the type median of 545.6 kg. It logged 1,167 hours at sea against a median of 3,155 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2022 (44,866 t) and the lowest 2019 (1,670 t). Its efficiency percentile within the type went from 30 in 2021 to 60 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,108 of 1,838 qualifying container ships by EEOI, at the 60th percentile. The dashed line is the type median, 14.2; this vessel reported 17.1.

EEOI divides emissions by transport work, which for this vessel and year was 795,413,005 tonne-miles over 18,275 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 475.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions rose 57.1% while distance sailed rose 43.8%and CO₂ per nautical mile rose 9.3%.That points mainly to how much the vessel sailed, rather than the other.
