ALDANA against its type
Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,340 gross tonnage it is larger than 74% 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 761 other vessels here, 193 of them oil tankers. The returns for 2019–2025 all give Panama as port of registry.
Its 3,429 t of CO₂ for 2025 is 57% 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 416.9 kg CO₂, close to the type median of 403.2 kg. It logged 664 hours at sea against a median of 2,030 hours for its type that year. 12.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2022 (14,961 t) and the lowest 2025 (3,429 t). Its efficiency percentile within the type went from 17 in 2019 to 21 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 308 of 1,448 qualifying oil tankers by EEOI, at the 21st percentile. The dashed line is the type median, 7.5; this vessel reported 5.3.
EEOI divides emissions by transport work, which for this vessel and year was 644,633,459 tonne-miles over 8,227 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 73.5% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 69.3% while distance sailed fell 68.8%and CO₂ per nautical mile fell 1.4%.That points mainly to how much the vessel sailed, rather than the other.
