SONGA OPAL against its type
It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The reported port of registry changed: Majuro (2021), then Valletta (2022–2025).
Its 9,094 t of CO₂ for 2025 is 15% 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 296.4 kg CO₂, 26% below the type median of 403.2 kg. It logged 3,741 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 5 years with reported emissions, the highest was 2023 (10,453 t) and the lowest 2021 (1,651 t). Its efficiency percentile within the type went from 54 in 2021 to 100 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,445 of 1,448 qualifying oil tankers by EEOI, at the 100th percentile. The dashed line is the type median, 7.5; this vessel reported 43.2.
EEOI divides emissions by transport work, which for this vessel and year was 210,567,492 tonne-miles over 30,679 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 450.8% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 5.8% and CO₂ per nautical mile fell 20.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
