BW LYNX against its type
Built in 2013, it is 3 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. The same builder is recorded for 180 other vessels here, 51 of them oil tankers. Its MRV returns name it BW LYNX for 2018–2022 and HAFNIA LYNX for 2024–2025. The returns for 2018–2025 all give Singapore as port of registry.
Its 6,176 t of CO₂ for 2025 is 22% 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 242.8 kg CO₂, 40% below the type median of 403.2 kg. It logged 2,273 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 6 years with reported emissions, the highest was 2019 (10,113 t) and the lowest 2024 (2,601 t). Its efficiency percentile within the type went from 56 in 2018 to 68 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 984 of 1,448 qualifying oil tankers by EEOI, at the 68th percentile. The dashed line is the type median, 7.5; this vessel reported 9.3.
EEOI divides emissions by transport work, which for this vessel and year was 666,239,482 tonne-miles over 25,437 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 38.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 137.5% while distance sailed rose 120.7%and CO₂ per nautical mile rose 7.6%.That points mainly to how much the vessel sailed, rather than the other.
