BIG DOG against its type
Built in 2003, it is 5 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 18,334 gross tonnage it is smaller than 77% 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 101 other vessels here, 74 of them container ships. The returns for 2023–2025 all give MONROVIA as port of registry.
Its 1,648 t of CO₂ for 2024 is 91% below the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 235.1 kg CO₂, 56% below the type median of 528.5 kg. It logged 563 hours at sea against a median of 3,325 hours for its type that year. 0.2% of its 2024 emissions were at berth; the median for container ships was 2.8%. The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Reported CO₂ by year
Reported CO₂ in 2024 was 80.7% higher than in 2023, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 80.7% and CO₂ per nautical mile fell 18.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
