MINERVA ZEN against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,442 gross tonnage it is larger than 73% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 18 chemical tankers here under the Greece flag, 0.8% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The returns for 2018–2025 all give Piraeus as port of registry.
Its 7,334 t of CO₂ for 2025 is 33% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 272.3 kg CO₂, close to the type median of 250.2 kg. It logged 2,656 hours at sea against a median of 2,109 hours for its type that year. 6.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2018 (14,754 t) and the lowest 2023 (3,409 t). Its efficiency percentile within the type went from 53 in 2018 to 40 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 540 of 1,348 qualifying chemical tankers by EEOI, at the 40th percentile. The dashed line is the type median, 14.4; this vessel reported 12.7.
EEOI divides emissions by transport work, which for this vessel and year was 579,312,796 tonne-miles over 26,931 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 50.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 49.9% while distance sailed rose 86.0%and CO₂ per nautical mile fell 19.4%.That points mainly to how much the vessel sailed, rather than the other.
