MARINER against its type
Built in 2015, it is 7 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 27,279 gross tonnage it is smaller than 67% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. Its MRV returns name it MARINER for 2021–2023 and MARY SCHULTE for 2024–2025. The returns for 2021–2025 all give Singapore as port of registry.
Its 9,673 t of CO₂ for 2024 is 46% below the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 323.6 kg CO₂, 39% below the type median of 528.5 kg. It logged 2,350 hours at sea against a median of 3,325 hours for its type that year. 1.2% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 4 years with reported emissions, the highest was 2024 (9,673 t) and the lowest 2021 (7,453 t). Its efficiency percentile within the type went from 76 in 2021 to 85 in 2024 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 1,412 of 1,661 qualifying container ships by EEOI, at the 85th percentile. The dashed line is the type median, 15.4; this vessel reported 32.7.
EEOI divides emissions by transport work, which for this vessel and year was 295,643,643 tonne-miles over 29,894 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 29.8% higher than in 2021, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 2.0% while distance sailed rose 4.7%and CO₂ per nautical mile fell 2.6%.That points mainly to how much the vessel sailed, rather than the other.
