CELSIUS MIAMI against its type
It is one of 8 chemical tankers here under the Tuvalu flag, 0.3% of the 2,344 on the register. Its MRV returns name it CELSIUS MIAMI for 2020 and MIAMI for 2023–2025. The reported port of registry changed: MAJURO (2020), then FUNAFUTI (2023–2025).
Its 6,672 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 185.4 kg CO₂, 26% below the type median of 250.2 kg. It logged 3,255 hours at sea against a median of 2,106 hours for its type that year. 5.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2025 (6,672 t) and the lowest 2020 (1,957 t). Its efficiency percentile within the type went from 45 in 2023 to 66 in 2025 (lower is more efficient). Of the 3 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 895 of 1,348 qualifying chemical tankers by EEOI, at the 66th percentile. The dashed line is the type median, 14.4; this vessel reported 19.3.
EEOI divides emissions by transport work, which for this vessel and year was 345,160,890 tonne-miles over 35,987 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 241.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 53.0% while distance sailed rose 83.0%and CO₂ per nautical mile fell 16.4%.That points mainly to how much the vessel sailed, rather than the other.
