COSWISDOM LAKE against its type
Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 162,542 gross tonnage it is larger than 97% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The same builder is recorded for 146 other vessels here, 55 of them oil tankers. The returns for 2023–2025 all give HONG KONG as port of registry.
Its 3,884 t of CO₂ for 2025 is 51% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 781.2 kg CO₂, 1.9 times the type median of 403.2 kg. It logged 397 hours at sea against a median of 2,030 hours for its type that year. 14.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Its efficiency percentile within the type went from 26 in 2023 to 3 in 2025 (lower is more efficient). Of the 2 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 44 of 1,448 qualifying oil tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 7.5; this vessel reported 3.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,159,289,552 tonne-miles over 4,971 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 31.1% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 31.1% while distance sailed fell 43.5%and CO₂ per nautical mile rose 22.0%.That points mainly to how much the vessel sailed, rather than the other.
