Its 4,614 t of CO₂ for 2020 is 47% below the median of 8,732 t among the 1,884 oil tankers on this register that reported for 2020. Per nautical mile it emitted 470.9 kg CO₂, 11% above the type median of 424.6 kg. It logged 922 hours at sea against a median of 1,939 hours for its type that year. 3.4% of its 2020 emissions were at berth; the median for oil tankers was 8.6%. Of the 2 comparable vessels listed below with a 2020 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2020
Position 276 of 1,708 qualifying oil tankers by EEOI, at the 16th percentile. The dashed line is the type median, 8.7; this vessel reported 5.5.
EEOI divides emissions by transport work, which for this vessel and year was 831,342,342 tonne-miles over 9,798 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2020 was 15.1% lower than in 2019, for EU/EEA voyages only.
From 2019 to 2020, emissions fell 15.1% and CO₂ per nautical mile fell 38.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
