IONIAN SEA against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,654 gross tonnage it is larger than 79% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it SAN FERNANDO for 2020–2022 and IONIAN SEA for 2025. The reported port of registry changed: DOUGLAS (2020–2022), then Monrovia (2025).
Its 3,307 t of CO₂ for 2025 is 40% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 341.1 kg CO₂, 36% above the type median of 250.2 kg. It logged 867 hours at sea against a median of 2,106 hours for its type that year. 4.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2022 (6,844 t) and the lowest 2020 (2,650 t). Its efficiency percentile within the type went from 46 in 2020 to 22 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 301 of 1,348 qualifying chemical tankers by EEOI, at the 22nd percentile. The dashed line is the type median, 14.4; this vessel reported 9.6.
EEOI divides emissions by transport work, which for this vessel and year was 346,258,639 tonne-miles over 9,693 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.8% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 51.7% while distance sailed fell 53.7%and CO₂ per nautical mile rose 4.4%.That points mainly to how much the vessel sailed, rather than the other.
