ARIANE: CO₂ emissions 2018–2025

ARIANE 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 42,010 gross tonnage it is smaller than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2018–2025 all give Monrovia as port of registry.

Its 4,730 t of CO₂ for 2025 is 40% 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 370.7 kg CO₂, close to the type median of 403.2 kg. It logged 1,140 hours at sea against a median of 2,030 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2018 (6,669 t) and the lowest 2020 (3,201 t). Its efficiency percentile within the type went from 89 in 2018 to 77 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,115 of 1,448 qualifying oil tankers by EEOI, at the 77th percentile. The dashed line is the type median, 7.5; this vessel reported 10.9.

EEOI divides emissions by transport work, which for this vessel and year was 435,546,040 tonne-miles over 12,760 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 29.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, 2023, 2024, so the series has gaps.

From 2020 to 2025, emissions rose 47.8% while distance sailed rose 33.7%and CO₂ per nautical mile rose 10.5%.That points mainly to how much the vessel sailed, rather than the other.
