SEINE HIGHWAY against its type
Built in 2007, it is 1 year older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 23,498 gross tonnage it is smaller than 96% of the other 571 vehicle carriers with a recorded tonnage. It is one of 73 vehicle carriers here under the Bahamas flag, 10.2% of the 713 on the register. The same builder is recorded for 75 other vessels here, 31 of them vehicle carriers. The returns for 2018–2025 all give Nassau as port of registry.
Its 17,867 t of CO₂ for 2025 is 2.5 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 243.6 kg CO₂, 21% below the type median of 309.1 kg. It logged 5,594 hours at sea against a median of 1,639 hours for its type that year. 10.4% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2019 (28,344 t) and the lowest 2024 (17,401 t). Its efficiency percentile within the type went from 94 in 2018 to 99 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 419 of 423 qualifying vehicle carriers by EEOI, at the 99th percentile. The dashed line is the type median, 51.7; this vessel reported 234.6.
EEOI divides emissions by transport work, which for this vessel and year was 76,147,162 tonne-miles over 73,349 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.7% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 2.7% while distance sailed rose 0.3%and CO₂ per nautical mile rose 2.3%.That points mainly to how efficiently it sailed, rather than the other.
