HARMONY N against its type
Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 28,592 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 983 other vessels here, 86 of them container ships. Its MRV returns name it HARMONY N for 2018–2020 and MSC HARMONY III for 2023–2025. The returns for 2018–2025 all give Monrovia as port of registry.
Its 14,172 t of CO₂ for 2025 is 13% 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 351.9 kg CO₂, 36% below the type median of 545.6 kg. It logged 4,353 hours at sea against a median of 3,155 hours for its type that year. 9.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2018 (26,543 t) and the lowest 2020 (4,772 t). Its efficiency percentile within the type went from 82 in 2018 to 67 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,227 of 1,838 qualifying container ships by EEOI, at the 67th percentile. The dashed line is the type median, 14.2; this vessel reported 19.1.
EEOI divides emissions by transport work, which for this vessel and year was 741,624,280 tonne-miles over 40,278 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 46.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 34.6% while distance sailed fell 17.2%and CO₂ per nautical mile fell 21.0%.
