COROSSOL against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 58,418 gross tonnage it is smaller than 51% 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. The same builder is recorded for 194 other vessels here, 56 of them oil tankers. The reported port of registry changed: Valletta (2018–2021), then Monrovia (2022–2025).
Its 4,991 t of CO₂ for 2025 is 37% 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 626.8 kg CO₂, 1.6 times the type median of 403.2 kg. It logged 754 hours at sea against a median of 2,030 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2024 (24,322 t) and the lowest 2023 (3,312 t). Its efficiency percentile within the type went from 5 in 2018 to 58 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 848 of 1,448 qualifying oil tankers by EEOI, at the 58th percentile. The dashed line is the type median, 7.5; this vessel reported 8.1.
EEOI divides emissions by transport work, which for this vessel and year was 613,876,999 tonne-miles over 7,962 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 52.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 79.5% while distance sailed fell 84.0%and CO₂ per nautical mile rose 28.5%.That points mainly to how much the vessel sailed, rather than the other.
