LADY HENRIETTA against its type
Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,452 gross tonnage it is larger than 59% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The reported port of registry changed: Valletta (2018–2021), then MAJURO (2022–2025).
Its 4,945 t of CO₂ for 2025 is 38% 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 483.9 kg CO₂, 20% above the type median of 403.2 kg. It logged 946 hours at sea against a median of 2,030 hours for its type that year. 9.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2018 (14,424 t) and the lowest 2021 (1,587 t). Its efficiency percentile within the type went from 41 in 2018 to 58 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 834 of 1,448 qualifying oil tankers by EEOI, at the 58th percentile. The dashed line is the type median, 7.5; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 615,839,352 tonne-miles over 10,218 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 65.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 33.6% while distance sailed fell 37.4%and CO₂ per nautical mile rose 6.2%.That points mainly to how much the vessel sailed, rather than the other.
