THALASSA AXIA against its type

Built in 2014, it is 6 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 149,475 gross tonnage it is larger than 90% 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 761 other vessels here, 355 of them container ships. Its MRV returns name it THALASSA AXIA for 2018–2023 and VANCOUVER EXPRESS for 2025. The reported port of registry changed: Singapore (2018), then Monrovia (2019–2025).

Its 36,426 t of CO₂ for 2025 is 2.2 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 765.6 kg CO₂, 40% above the type median of 545.6 kg. It logged 3,264 hours at sea against a median of 3,155 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2023 (44,687 t) and the lowest 2022 (10,437 t). Its efficiency percentile within the type went from 13 in 2018 to 4 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 70 of 1,838 qualifying container ships by EEOI, at the 4th percentile. The dashed line is the type median, 14.2; this vessel reported 6.1.

EEOI divides emissions by transport work, which for this vessel and year was 5,961,710,311 tonne-miles over 47,577 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 39.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions fell 18.5% while distance sailed fell 10.0%and CO₂ per nautical mile fell 9.4%.
