PHILOXENIA against its type
Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,551 gross tonnage it is larger than 76% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. The returns for 2019–2025 all give MAJURO as port of registry.
Its 7,649 t of CO₂ for 2025 is 38% 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 215.9 kg CO₂, 14% below the type median of 250.2 kg. It logged 2,994 hours at sea against a median of 2,106 hours for its type that year. 4.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2025 (7,649 t) and the lowest 2022 (2,114 t). Its efficiency percentile within the type went from 51 in 2019 to 4 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 61 of 1,348 qualifying chemical tankers by EEOI, at the 4th percentile. The dashed line is the type median, 14.4; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 1,086,566,761 tonne-miles over 35,422 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 80.5% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 261.9% while distance sailed rose 245.1%and CO₂ per nautical mile rose 4.8%.That points mainly to how much the vessel sailed, rather than the other.
