CLIO against its type

Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,789 gross tonnage it is larger than 61% of the other 2,841 oil tankers with a recorded tonnage. It is one of 56 oil tankers here under the Portugal flag, 1.6% of the 3,548 on the register. The returns for 2018–2025 all give Madeira as port of registry.

Its 17,939 t of CO₂ for 2025 is 2.3 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 487.6 kg CO₂, 21% above the type median of 403.2 kg. It logged 3,105 hours at sea against a median of 2,030 hours for its type that year. 4.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (22,083 t) and the lowest 2024 (2,065 t). Its efficiency percentile within the type went from 27 in 2018 to 18 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 260 of 1,448 qualifying oil tankers by EEOI, at the 18th percentile. The dashed line is the type median, 7.5; this vessel reported 5.0.

EEOI divides emissions by transport work, which for this vessel and year was 3,580,674,651 tonne-miles over 36,793 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 18.8% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 768.7% while distance sailed rose 702.8%and CO₂ per nautical mile rose 8.2%.That points mainly to how much the vessel sailed, rather than the other.
