FLENSBURG against its type
Built in 2002, it is 6 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,990 gross tonnage it is smaller than 89% of the other 3,000 container ships with a recorded tonnage. It is one of 3 container ships here under the Latvia flag, 0.1% of the 3,495 on the register. The same builder is recorded for 180 other vessels here, 110 of them container ships. Its MRV returns name it FLENSBURG for 2018–2020, NCL SALTEN for 2022–2024 and ODYSSEY for 2025. The reported port of registry changed: Limassol (2018–2024), then Riga (2025).
Its 12,888 t of CO₂ for 2025 is 21% 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 231.9 kg CO₂, 58% below the type median of 545.6 kg. It logged 4,019 hours at sea against a median of 3,155 hours for its type that year. 8.3% 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 (18,242 t) and the lowest 2022 (3,892 t). Its efficiency percentile within the type went from 99 in 2018 to 94 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,726 of 1,838 qualifying container ships by EEOI, at the 94th percentile. The dashed line is the type median, 14.2; this vessel reported 43.7.
EEOI divides emissions by transport work, which for this vessel and year was 295,050,137 tonne-miles over 55,580 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 25.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 20.4% while distance sailed fell 15.6%and CO₂ per nautical mile fell 5.7%.That points mainly to how much the vessel sailed, rather than the other.
