MSC ALTAIR against its type

Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 141,635 gross tonnage it is larger than 87% 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 761 other vessels here, 355 of them container ships. Zeaborn Ship Management is linked to 56 vessels on this register. The returns for 2018–2025 all give MONROVIA as port of registry.

Its 27,384 t of CO₂ for 2025 is 1.7 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 885.3 kg CO₂, 1.6 times the type median of 545.6 kg. It logged 2,319 hours at sea against a median of 3,155 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2024 (54,910 t) and the lowest 2019 (8,063 t). Its efficiency percentile within the type went from 15 in 2018 to 17 in 2025 (lower is more efficient). Of the 4 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 321 of 1,838 qualifying container ships by EEOI, at the 17th percentile. The dashed line is the type median, 14.2; this vessel reported 7.9.

Across the 43 ranked vessels operated by Zeaborn Ship Management, the median percentile is 45. This vessel is more efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 3,461,929,204 tonne-miles over 30,932 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 215.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions fell 50.1% while distance sailed fell 48.1%and CO₂ per nautical mile fell 4.0%.That points mainly to how much the vessel sailed, rather than the other.
