CELSIUS MONTREAL against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,731 gross tonnage it is smaller than 74% 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 CELSIUS MONTREAL for 2020–2022 and PRABHU PARVATI for 2024–2025. The reported port of registry changed: MAJURO (2020–2022), then Singapore (2024–2025).
Its 6,694 t of CO₂ for 2025 is 21% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 201.6 kg CO₂, 19% below the type median of 250.2 kg. It logged 3,043 hours at sea against a median of 2,106 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2021 (6,837 t) and the lowest 2020 (1,933 t). Its efficiency percentile within the type went from 68 in 2020 to 50 in 2025 (lower is more efficient). Of the 5 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 679 of 1,348 qualifying chemical tankers by EEOI, at the 50th percentile. The dashed line is the type median, 14.4; this vessel reported 14.5.
EEOI divides emissions by transport work, which for this vessel and year was 462,299,724 tonne-miles over 33,208 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 246.2% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 33.4% while distance sailed rose 22.8%and CO₂ per nautical mile rose 8.7%.That points mainly to how much the vessel sailed, rather than the other.
