CHIOS LION against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 60,379 gross tonnage it is larger than 53% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 360 other vessels here, 27 of them oil tankers. Its MRV returns name it CHIOS LION for 2024 and TIGERLILY for 2025. The returns for 2024–2025 all give Monrovia as port of registry.
Its 2,049 t of CO₂ for 2025 is 74% 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 424.0 kg CO₂, close to the type median of 403.2 kg. It logged 399 hours at sea against a median of 2,030 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Its efficiency percentile within the type went from 77 in 2024 to 14 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 208 of 1,448 qualifying oil tankers by EEOI, at the 14th percentile. The dashed line is the type median, 7.5; this vessel reported 4.8.
EEOI divides emissions by transport work, which for this vessel and year was 429,465,409 tonne-miles over 4,832 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 74.4% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 74.4% while distance sailed fell 58.3%and CO₂ per nautical mile fell 38.5%.That points mainly to how much the vessel sailed, rather than the other.
