AROSA against its type

It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The returns for 2018–2025 all give PIRAEUS as port of registry.

Its 19,477 t of CO₂ for 2025 is 2.5 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 614.6 kg CO₂, 1.5 times the type median of 403.2 kg. It logged 2,692 hours at sea against a median of 2,030 hours for its type that year. 8.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2025 (19,477 t) and the lowest 2018 (5,305 t). Its efficiency percentile within the type went from 11 in 2018 to 14 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 206 of 1,448 qualifying oil tankers by EEOI, at the 14th percentile. The dashed line is the type median, 7.5; this vessel reported 4.8.

EEOI divides emissions by transport work, which for this vessel and year was 4,091,890,756 tonne-miles over 31,693 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 267.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions rose 112.5% while distance sailed rose 80.4%and CO₂ per nautical mile rose 17.8%.That points mainly to how much the vessel sailed, rather than the other.
