RS TARA against its type
It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The reported port of registry changed: Majuro (2019), then Majuro, Marshall Islands (2020–2025).
Its 10,724 t of CO₂ for 2025 is 35% 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 513.8 kg CO₂, 27% above the type median of 403.2 kg. It logged 1,971 hours at sea against a median of 2,030 hours for its type that year. 10.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2024 (14,723 t) and the lowest 2018 (3,769 t). Its efficiency percentile within the type went from 5 in 2018 to 67 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 972 of 1,448 qualifying oil tankers by EEOI, at the 67th percentile. The dashed line is the type median, 7.5; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 1,165,681,522 tonne-miles over 20,874 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 184.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 27.2% while distance sailed fell 29.7%and CO₂ per nautical mile rose 3.6%.That points mainly to how much the vessel sailed, rather than the other.
