ST. PETRI against its type
It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. Its MRV returns name it ST.PETRI for 2019–2024 and ST. PETRI for 2025. The returns for 2019–2025 all give SINGAPORE as port of registry.
Its 2,014 t of CO₂ for 2025 is 64% 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 228.2 kg CO₂, close to the type median of 250.2 kg. It logged 798 hours at sea against a median of 2,106 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (7,885 t) and the lowest 2023 (586 t). Its efficiency percentile within the type went from 44 in 2019 to 1 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 12 of 1,348 qualifying chemical tankers by EEOI, at the 1st percentile. The dashed line is the type median, 14.4; this vessel reported 5.6.
EEOI divides emissions by transport work, which for this vessel and year was 360,259,392 tonne-miles over 8,826 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 50.8% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 74.5% while distance sailed fell 68.0%and CO₂ per nautical mile fell 20.2%.That points mainly to how much the vessel sailed, rather than the other.
