HAMMONIA BALTICA 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 28,561 gross tonnage it is smaller than 65% 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 16 other vessels here, all of them container ships. Its MRV returns name it INDEPENDENT VOYAGER for 2018 and HAMMONIA BALTICA for 2019–2025. The returns for 2018–2025 all give Monrovia as port of registry.
Its 25,338 t of CO₂ for 2025 is 1.5 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 401.4 kg CO₂, 26% below the type median of 545.6 kg. It logged 4,638 hours at sea against a median of 3,155 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (37,338 t) and the lowest 2023 (8,434 t). Its efficiency percentile within the type went from 52 in 2018 to 74 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,361 of 1,838 qualifying container ships by EEOI, at the 74th percentile. The dashed line is the type median, 14.2; this vessel reported 22.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,130,130,241 tonne-miles over 63,128 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 32.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 57.0% while distance sailed rose 72.9%and CO₂ per nautical mile fell 9.2%.That points mainly to how much the vessel sailed, rather than the other.
