NEOKASTRO: CO₂ emissions 2022–2025

NEOKASTRO against its type

Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 42,609 gross tonnage it is smaller 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. The returns for 2022–2025 all give Monrovia as port of registry.

Its 19,799 t of CO₂ for 2025 is 21% 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 549.9 kg CO₂, close to the type median of 545.6 kg. It logged 3,405 hours at sea against a median of 3,155 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2023 (37,508 t) and the lowest 2025 (19,799 t). Its efficiency percentile within the type went from 59 in 2022 to 71 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,310 of 1,838 qualifying container ships by EEOI, at the 71st percentile. The dashed line is the type median, 14.2; this vessel reported 21.2.

EEOI divides emissions by transport work, which for this vessel and year was 935,227,208 tonne-miles over 36,007 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 35.0% lower than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 4.6% while distance sailed fell 8.3%and CO₂ per nautical mile rose 4.1%.That points mainly to how much the vessel sailed, rather than the other.
