CELSIUS MAYFAIR against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,660 gross tonnage it is smaller than 75% 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. The same builder is recorded for 52 other vessels here, 48 of them chemical tankers. Its MRV returns name it CELSIUS MAYFAIR for 2018–2022 and OM SHANGHAI for 2025. The returns for 2018–2025 all give MAJURO as port of registry.
Its 250 t of CO₂ for 2025 is 95% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 163.3 kg CO₂, 35% below the type median of 250.2 kg. It logged 134 hours at sea against a median of 2,106 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2022 (7,549 t) and the lowest 2025 (250 t). Its efficiency percentile within the type went from 68 in 2018 to 4 in 2022 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 94.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 96.7% and CO₂ per nautical mile fell 19.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
