CELSIUS MANHATTAN against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,615 gross tonnage it is smaller than 76% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it CELSIUS MANHATTAN for 2020 and T VEGA for 2023–2025. The reported port of registry changed: MAJURO (2020), then MONROVIA (2023–2025).
Its 1,580 t of CO₂ for 2025 is 71% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 189.0 kg CO₂, 24% below the type median of 250.2 kg. It logged 790 hours at sea against a median of 2,109 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (3,600 t) and the lowest 2024 (1,044 t). Its efficiency percentile within the type went from 19 in 2020 to 40 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 546 of 1,348 qualifying chemical tankers by EEOI, at the 40th percentile. The dashed line is the type median, 14.4; this vessel reported 12.7.
EEOI divides emissions by transport work, which for this vessel and year was 124,340,677 tonne-miles over 8,360 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 21.6% lower 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 51.4% and CO₂ per nautical mile fell 40.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
