COSWISH LAKE against its type
Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 165,511 gross tonnage it is larger than 99% 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 2018–2025 all give Hong Kong as port of registry.
Its 7,631 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 676.5 kg CO₂, 1.7 times the type median of 403.2 kg. It logged 1,074 hours at sea against a median of 2,030 hours for its type that year. 7.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2018 (11,831 t) and the lowest 2025 (7,631 t). Its efficiency percentile within the type went from 1 in 2018 to 12 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 181 of 1,448 qualifying oil tankers by EEOI, at the 12th percentile. The dashed line is the type median, 7.5; this vessel reported 4.6.
EEOI divides emissions by transport work, which for this vessel and year was 1,655,420,824 tonne-miles over 11,280 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, 2024, so the series has gaps.
From 2019 to 2025, emissions fell 28.8% while distance sailed fell 33.9%and CO₂ per nautical mile rose 7.8%.That points mainly to how much the vessel sailed, rather than the other.
