CELSIUS MUMBAI against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,571 gross tonnage it is smaller than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it CELSIUS MUMBAI for 2018–2020 and F MUMBAI for 2024. The reported port of registry changed: MAJURO (2018–2020), then Marshall Islands (2024).
Its 1,186 t of CO₂ for 2024 is 80% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 173.1 kg CO₂, 32% below the type median of 253.5 kg. It logged 566 hours at sea against a median of 2,177 hours for its type that year. 0.7% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 3 years with reported emissions, the highest was 2018 (6,285 t) and the lowest 2020 (920 t). Its efficiency percentile within the type went from 41 in 2018 to 42 in 2024 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 496 of 1,194 qualifying chemical tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 15.9; this vessel reported 13.8.
EEOI divides emissions by transport work, which for this vessel and year was 86,176,599 tonne-miles over 6,851 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 81.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, 2023, so the series has gaps.
From 2020 to 2024, emissions rose 28.9% and CO₂ per nautical mile fell 29.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
