ZOILO against its type

Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,785 gross tonnage it is larger than 84% 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 983 other vessels here, 330 of them chemical tankers. The reported port of registry changed: Zadar (2018–2020), then Valletta (2021–2025).

Its 3,405 t of CO₂ for 2025 is 38% 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 249.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,303 hours at sea against a median of 2,106 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (9,018 t) and the lowest 2021 (2,698 t). Its efficiency percentile within the type went from 18 in 2018 to 21 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 281 of 1,348 qualifying chemical tankers by EEOI, at the 21st percentile. The dashed line is the type median, 14.4; this vessel reported 9.2.

EEOI divides emissions by transport work, which for this vessel and year was 368,111,351 tonne-miles over 13,652 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 55.7% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 25.1% while distance sailed rose 33.0%and CO₂ per nautical mile fell 6.0%.That points mainly to how much the vessel sailed, rather than the other.
