MARIE S against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,225 gross tonnage it is larger than 69% of the other 1,899 chemical tankers with a recorded tonnage. 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 MARIE S for 2018–2022 and TORM DIANA for 2025. The reported port of registry changed: Majuro (2018–2022), then Singapore (2025).
Its 5,770 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 213.1 kg CO₂, 15% below the type median of 250.2 kg. It logged 2,334 hours at sea against a median of 2,106 hours for its type that year. 6.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2020 (8,617 t) and the lowest 2018 (2,829 t). Its efficiency percentile within the type went from 3 in 2018 to 4 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 62 of 1,348 qualifying chemical tankers by EEOI, at the 4th percentile. The dashed line is the type median, 14.4; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 818,499,291 tonne-miles over 27,073 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 104.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 0.8% while distance sailed rose 36.7%and CO₂ per nautical mile fell 26.3%.
