NAVIOS CONSTELLATION against its type
Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 113,412 gross tonnage it is larger than 83% 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 563 other vessels here, 243 of them container ships. The returns for 2019–2025 all give MONROVIA as port of registry.
Its 1,571 t of CO₂ for 2025 is 90% 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 817.3 kg CO₂, 50% above the type median of 545.6 kg. It logged 187 hours at sea against a median of 3,155 hours for its type that year. 19.3% 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 (25,785 t) and the lowest 2023 (1,488 t). Its efficiency percentile within the type went from 35 in 2019 to 27 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 81.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 93.9% and CO₂ per nautical mile rose 2.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
