HISTRIA AZURE against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 25,804 gross tonnage it is smaller than 87% 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 21 other vessels here, 14 of them oil tankers. Histria Shipmanagement is linked to 8 vessels on this register. The returns for 2018–2025 all give Majuro as port of registry.
Its 7,507 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 279.4 kg CO₂, 31% below the type median of 403.2 kg. It logged 2,760 hours at sea against a median of 2,030 hours for its type that year. 16.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2023 (12,439 t) and the lowest 2025 (7,507 t). Its efficiency percentile within the type went from 86 in 2018 to 84 in 2025 (lower is more efficient). Of the 8 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 1,220 of 1,448 qualifying oil tankers by EEOI, at the 84th percentile. The dashed line is the type median, 7.5; this vessel reported 13.8.
Across the 8 ranked vessels operated by Histria Shipmanagement, the median percentile is 89. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 544,017,391 tonne-miles over 26,868 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 24.4% while distance sailed fell 15.7%and CO₂ per nautical mile fell 10.3%.That points mainly to how much the vessel sailed, rather than the other.
