PYXIS THETA against its type
Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,159 gross tonnage it is larger than 93% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. The returns for 2019–2025 all give Valletta as port of registry.
Its 5,533 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 334.5 kg CO₂, 34% above the type median of 250.2 kg. It logged 1,456 hours at sea against a median of 2,109 hours for its type that year. 11.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2021 (13,455 t) and the lowest 2022 (2,075 t). Its efficiency percentile within the type went from 5 in 2019 to 45 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 608 of 1,348 qualifying chemical tankers by EEOI, at the 45th percentile. The dashed line is the type median, 14.4; this vessel reported 13.4.
EEOI divides emissions by transport work, which for this vessel and year was 411,384,387 tonne-miles over 16,542 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.8% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 40.0% while distance sailed fell 48.4%and CO₂ per nautical mile rose 16.3%.That points mainly to how much the vessel sailed, rather than the other.
