JAARLI against its type

It is one of 4 oil tankers here under the Finland flag, 0.1% of the 3,548 on the register. The returns for 2021–2025 all give Porvoo as port of registry.

Its 25,977 t of CO₂ for 2025 is 3.3 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 471.7 kg CO₂, 17% above the type median of 403.2 kg. It logged 6,469 hours at sea against a median of 2,030 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2023 (25,985 t) and the lowest 2021 (835 t). Its efficiency percentile within the type went from 76 in 2022 to 72 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,048 of 1,448 qualifying oil tankers by EEOI, at the 72nd percentile. The dashed line is the type median, 7.5; this vessel reported 10.1.

EEOI divides emissions by transport work, which for this vessel and year was 2,577,126,984 tonne-miles over 55,071 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 3,011.7% higher than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 3.2% while distance sailed rose 1.1%and CO₂ per nautical mile rose 2.1%.That points mainly to how efficiently it sailed, rather than the other.
