TAIGA 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 160,109 gross tonnage it is larger than 92% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. Its MRV returns name it TAIGA for 2020 and UNION PEACE for 2025. The reported port of registry changed: PANAMA (2020), then Hong Kong (2025).
Its 15,572 t of CO₂ for 2025 is 2.0 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 737.4 kg CO₂, 1.8 times the type median of 403.2 kg. It logged 1,796 hours at sea against a median of 2,030 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Its efficiency percentile within the type went from 18 in 2020 to 23 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 332 of 1,448 qualifying oil tankers by EEOI, at the 23rd percentile. The dashed line is the type median, 7.5; this vessel reported 5.5.
EEOI divides emissions by transport work, which for this vessel and year was 2,857,317,431 tonne-miles over 21,119 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 194.3% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions rose 194.3% while distance sailed rose 147.9%and CO₂ per nautical mile rose 18.7%.That points mainly to how much the vessel sailed, rather than the other.
