OBERON against its type

Built in 2008, it is the same age as the median vehicle carrier on this register (build year 2008, 595 vessels with a known build year). At 71,673 gross tonnage it is larger than 90% of the other 571 vehicle carriers with a recorded tonnage. It is one of 14 vehicle carriers here under the Sweden flag, 2.0% of the 713 on the register. The same builder is recorded for 660 other vessels here, 45 of them vehicle carriers. The returns for 2023–2025 all give Stockholm as port of registry.

Its 14,548 t of CO₂ for 2025 is 2.1 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 339.4 kg CO₂, close to the type median of 309.1 kg. It logged 2,948 hours at sea against a median of 1,639 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2018 (16,220 t) and the lowest 2024 (3,437 t). Its efficiency percentile within the type went from 24 in 2018 to 6 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 27 of 423 qualifying vehicle carriers by EEOI, at the 6th percentile. The dashed line is the type median, 51.7; this vessel reported 31.2.

EEOI divides emissions by transport work, which for this vessel and year was 465,549,440 tonne-miles over 42,865 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 10.3% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 323.3% while distance sailed rose 331.7%and CO₂ per nautical mile fell 2.0%.That points mainly to how much the vessel sailed, rather than the other.
