ISABELLA against its type
Built in 2004, it is 6 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 57,301 gross tonnage it is smaller than 53% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 461 other vessels here, 179 of them oil tankers. The returns for 2018–2023 all give VALLETTA as port of registry.
Its 8,927 t of CO₂ for 2023 is 19% above the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 466.4 kg CO₂, 14% above the type median of 408.5 kg. It logged 1,896 hours at sea against a median of 1,807 hours for its type that year. 10.5% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 5 years with reported emissions, the highest was 2019 (18,457 t) and the lowest 2022 (1,502 t). Its efficiency percentile within the type went from 55 in 2018 to 76 in 2023 (lower is more efficient). Of the 2 sister ships listed below with a 2023 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 1,234 of 1,615 qualifying oil tankers by EEOI, at the 76th percentile. The dashed line is the type median, 8.0; this vessel reported 11.5.
EEOI divides emissions by transport work, which for this vessel and year was 773,589,255 tonne-miles over 19,142 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 39.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2022 to 2023, emissions rose 494.5% and CO₂ per nautical mile fell 8.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
