STENA PROSPEROUS against its type
It is one of 27 chemical tankers here under the Cyprus flag, 1.2% of the 2,344 on the register. The returns for 2023–2025 all give Limassol as port of registry.
Its 10,788 t of CO₂ for 2025 is 2.0 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 220.2 kg CO₂, 12% below the type median of 250.2 kg. It logged 4,337 hours at sea against a median of 2,106 hours for its type that year. 7.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (10,788 t) and the lowest 2023 (2,108 t). Its efficiency percentile within the type went from 1 in 2023 to 5 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 74 of 1,348 qualifying chemical tankers by EEOI, at the 5th percentile. The dashed line is the type median, 14.4; this vessel reported 7.3.
EEOI divides emissions by transport work, which for this vessel and year was 1,481,803,571 tonne-miles over 48,996 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 411.6% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 25.9% while distance sailed rose 20.9%and CO₂ per nautical mile rose 4.1%.That points mainly to how much the vessel sailed, rather than the other.
