OLYMPIOS against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2021–2024 all give MONROVIA as port of registry.
Its 7,130 t of CO₂ for 2025 is 29% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 252.8 kg CO₂, close to the type median of 250.2 kg. It logged 2,565 hours at sea against a median of 2,106 hours for its type that year. 10.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2025 (7,130 t) and the lowest 2022 (3,331 t). Its efficiency percentile within the type went from 24 in 2021 to 37 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 507 of 1,348 qualifying chemical tankers by EEOI, at the 37th percentile. The dashed line is the type median, 14.4; this vessel reported 12.2.
EEOI divides emissions by transport work, which for this vessel and year was 582,485,294 tonne-miles over 28,205 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 31.6% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 34.4% while distance sailed rose 70.4%and CO₂ per nautical mile fell 21.1%.That points mainly to how much the vessel sailed, rather than the other.
