BALOS against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 25,400 gross tonnage it is smaller than 87% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. Its MRV returns name it LEON HERMES for 2018–2023 and BALOS for 2024–2025. The returns for 2018–2025 all give Monrovia as port of registry.
Its 2,786 t of CO₂ for 2025 is 65% 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 281.2 kg CO₂, 30% below the type median of 403.2 kg. It logged 1,112 hours at sea against a median of 2,030 hours for its type that year. 6.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2022 (12,081 t) and the lowest 2025 (2,786 t). Its efficiency percentile within the type went from 91 in 2018 to 55 in 2024 (lower is more efficient). Of the 2 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 74.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 53.4% and CO₂ per nautical mile fell 11.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
