CLEAROCEAN MAVERICK 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 returns for 2021–2024 all give Monrovia as port of registry.
Its 266 t of CO₂ for 2025 is 97% 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 234.0 kg CO₂, 42% below the type median of 403.2 kg. It logged 95 hours at sea against a median of 2,030 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2021 (6,332 t) and the lowest 2025 (266 t). Its efficiency percentile within the type went from 54 in 2021 to 81 in 2024 (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.

Reported CO₂ by year
Reported CO₂ in 2025 was 95.8% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 94.0% and CO₂ per nautical mile fell 6.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
