BOW AGATHE against its type
Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 19,440 gross tonnage it is smaller than 93% of the other 2,841 oil tankers with a recorded tonnage. It is one of 58 oil tankers here under the Norway flag, 1.6% of the 3,548 on the register. The same builder is recorded for 76 other vessels here. Its MRV returns name it LIBERTY for 2020 and BOW AGATHE for 2021–2025. The returns for 2021–2025 all give Bergen as port of registry.
Its 11,556 t of CO₂ for 2025 is 46% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 278.4 kg CO₂, 31% below the type median of 403.2 kg. It logged 3,314 hours at sea against a median of 2,030 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (11,556 t) and the lowest 2020 (3,690 t). Its efficiency percentile within the type went from 47 in 2020 to 88 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,274 of 1,448 qualifying oil tankers by EEOI, at the 88th percentile. The dashed line is the type median, 7.5; this vessel reported 16.5.
EEOI divides emissions by transport work, which for this vessel and year was 700,773,196 tonne-miles over 41,512 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 213.2% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 34.0% while distance sailed rose 64.1%and CO₂ per nautical mile fell 18.3%.That points mainly to how much the vessel sailed, rather than the other.
