TAVISTOCK SQUARE against its type
It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The reported port of registry changed: Monrovia (2019), then MONROVIA, LIBERIA (2020), then Monrovia (2021–2025).
Its 6,128 t of CO₂ for 2025 is 23% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 324.0 kg CO₂, 20% below the type median of 403.2 kg. It logged 1,699 hours at sea against a median of 2,030 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2020 (13,414 t) and the lowest 2021 (1,182 t). Its efficiency percentile within the type went from 2 in 2019 to 23 in 2025 (lower is more efficient). Of the 7 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 340 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 1,116,145,720 tonne-miles over 18,914 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.6% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2021 to 2025, emissions rose 418.5% while distance sailed rose 473.6%and CO₂ per nautical mile fell 9.6%.That points mainly to how much the vessel sailed, rather than the other.
