ATLANTIC EMERALD 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 2022–2025 all give Monrovia as port of registry.
Its 15,446 t of CO₂ for 2025 is 1.9 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 357.4 kg CO₂, 11% below the type median of 403.2 kg. It logged 4,630 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 2025 (15,446 t) and the lowest 2024 (10,937 t). Its efficiency percentile within the type went from 11 in 2022 to 44 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 632 of 1,448 qualifying oil tankers by EEOI, at the 44th percentile. The dashed line is the type median, 7.5; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 2,216,015,782 tonne-miles over 43,212 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 17.0% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 41.2% while distance sailed rose 58.3%and CO₂ per nautical mile fell 10.8%.That points mainly to how much the vessel sailed, rather than the other.
