ZEPHYR LUMOS against its type
Built in 2021, it is 13 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 149,525 gross tonnage it is larger than 90% of the other 3,000 container ships with a recorded tonnage. It is one of 69 container ships here under the United Kingdom flag, 2.0% of the 3,495 on the register. Ocean Network Express is linked to 30 vessels on this register. The returns for 2021–2025 all give LONDON as port of registry.
Its 28,720 t of CO₂ for 2025 is 1.8 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 711.5 kg CO₂, 30% above the type median of 545.6 kg. It logged 4,004 hours at sea against a median of 3,155 hours for its type that year. 2.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2022 (39,421 t) and the lowest 2023 (10,672 t). Its efficiency percentile within the type went from 8 in 2021 to 4 in 2025 (lower is more efficient). Of the 7 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 71 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.
Across the 30 ranked vessels operated by Ocean Network Express, the median percentile is 11. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 4,692,831,699 tonne-miles over 40,364 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 17.7% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 40.6% while distance sailed rose 44.7%and CO₂ per nautical mile fell 2.8%.That points mainly to how much the vessel sailed, rather than the other.
