AS CONSTANTINA: CO₂ emissions 2021–2025

AS CONSTANTINA against its type

Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 27,786 gross tonnage it is smaller than 66% 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 61 other vessels here, 49 of them container ships. Columbia Shipmanagement is linked to 42 vessels on this register. The reported port of registry changed: Madeira (2021), then Monrovia (2022–2025).

Its 13,553 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 401.1 kg CO₂, 26% below the type median of 545.6 kg. It logged 3,245 hours at sea against a median of 3,155 hours for its type that year. 6.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2024 (26,510 t) and the lowest 2021 (3,036 t). Its efficiency percentile within the type went from 57 in 2022 to 72 in 2025 (lower is more efficient). Of the 2 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 1,321 of 1,838 qualifying container ships by EEOI, at the 72nd percentile. The dashed line is the type median, 14.2; this vessel reported 21.5.

Across the 41 ranked vessels operated by Columbia Shipmanagement, the median percentile is 53. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 630,653,792 tonne-miles over 33,791 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 346.5% higher than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 48.9% while distance sailed fell 48.9%and CO₂ per nautical mile rose <0.1%.That points mainly to how much the vessel sailed, rather than the other.
