EVER ARM against its type
Built in 2022, it is 14 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 235,579 gross tonnage it is larger than 99% of the other 3,000 container ships with a recorded tonnage. It is one of 6 container ships here under the Taiwan flag, 0.2% of the 3,495 on the register. The same builder is recorded for 563 other vessels here, 243 of them container ships. Evergreen Marine is linked to 27 vessels on this register. The returns for 2022–2025 all give Keelung as port of registry.
Its 84,868 t of CO₂ for 2025 is 5.2 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 1,195.5 kg CO₂, 2.2 times the type median of 545.6 kg. It logged 3,935 hours at sea against a median of 3,155 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2024 (95,890 t) and the lowest 2022 (53,754 t). Its efficiency percentile within the type went from 12 in 2022 to 10 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 185 of 1,838 qualifying container ships by EEOI, at the 10th percentile. The dashed line is the type median, 14.2; this vessel reported 7.0.
Across the 24 ranked vessels operated by Evergreen Marine, the median percentile is 20. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 12,193,711,207 tonne-miles over 70,993 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.9% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 11.5% and CO₂ per nautical mile rose 1.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
