STENA CONVOY against its type
It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The returns for 2022–2025 all give PANAMA as port of registry.
Its 2,516 t of CO₂ for 2025 is 54% 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 408.6 kg CO₂, 1.6 times the type median of 250.2 kg. It logged 547 hours at sea against a median of 2,106 hours for its type that year. 9.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2022 (5,139 t) and the lowest 2025 (2,516 t). Its efficiency percentile within the type went from 46 in 2022 to 37 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 497 of 1,348 qualifying chemical tankers by EEOI, at the 37th percentile. The dashed line is the type median, 14.4; this vessel reported 12.2.
EEOI divides emissions by transport work, which for this vessel and year was 206,949,013 tonne-miles over 6,158 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.0% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 22.1% while distance sailed fell 49.7%and CO₂ per nautical mile rose 55.0%.
