STENA PRO PATRIA 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 2022–2025 all give Limassol as port of registry.
Its 3,125 t of CO₂ for 2025 is 44% 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 257.8 kg CO₂, close to the type median of 250.2 kg. It logged 1,172 hours at sea against a median of 2,106 hours for its type that year. 4.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2024 (5,164 t) and the lowest 2022 (1,970 t). Its efficiency percentile within the type went from 8 in 2022 to 28 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 376 of 1,348 qualifying chemical tankers by EEOI, at the 28th percentile. The dashed line is the type median, 14.4; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 293,406,573 tonne-miles over 12,122 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 58.6% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 39.5% while distance sailed fell 42.6%and CO₂ per nautical mile rose 5.4%.That points mainly to how much the vessel sailed, rather than the other.
