RIVER OAK against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,530 gross tonnage it is smaller than 86% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The returns for 2024–2025 all give Majuro as port of registry.
Its 2,464 t of CO₂ for 2025 is 55% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 199.2 kg CO₂, 20% below the type median of 250.2 kg. It logged 1,271 hours at sea against a median of 2,109 hours for its type that year. 9.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 87 in 2024 to 89 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,205 of 1,348 qualifying chemical tankers by EEOI, at the 89th percentile. The dashed line is the type median, 14.4; this vessel reported 36.3.
EEOI divides emissions by transport work, which for this vessel and year was 67,842,236 tonne-miles over 12,372 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 54.0% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 54.0% while distance sailed fell 53.9%and CO₂ per nautical mile fell 0.2%.That points mainly to how much the vessel sailed, rather than the other.
