TILOS I 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 82,077 gross tonnage it is larger than 78% 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 returns for 2019–2025 all give MONROVIA as port of registry.
Its 4,698 t of CO₂ for 2025 is 41% 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 601.7 kg CO₂, 49% above the type median of 403.2 kg. It logged 1,203 hours at sea against a median of 2,030 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2024 (6,491 t) and the lowest 2022 (2,063 t). Its efficiency percentile within the type went from 5 in 2019 to 44 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 642 of 1,448 qualifying oil tankers by EEOI, at the 44th percentile. The dashed line is the type median, 7.5; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 668,315,790 tonne-miles over 7,808 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 126.0% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 27.6% while distance sailed fell 37.9%and CO₂ per nautical mile rose 16.5%.That points mainly to how much the vessel sailed, rather than the other.
