ST. CLEMENS against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,365 gross tonnage it is smaller than 79% of the other 2,841 oil tankers with a recorded tonnage. It is one of 244 oil tankers here under the Panama flag, 6.9% of the 3,548 on the register. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. The returns for 2019–2025 all give PANAMA as port of registry.
Its 7,011 t of CO₂ for 2025 is 12% 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 235.9 kg CO₂, 41% below the type median of 403.2 kg. It logged 2,790 hours at sea against a median of 2,030 hours for its type that year. 8.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2020 (8,261 t) and the lowest 2019 (2,131 t). Its efficiency percentile within the type went from 30 in 2019 to 53 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 774 of 1,448 qualifying oil tankers by EEOI, at the 53rd percentile. The dashed line is the type median, 7.5; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 908,102,332 tonne-miles over 29,722 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 228.9% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 35.9% while distance sailed rose 23.0%and CO₂ per nautical mile rose 10.5%.That points mainly to how much the vessel sailed, rather than the other.
