SC MERCURY against its type
It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. The returns for 2019–2025 all give Hong Kong as port of registry.
Its 3,037 t of CO₂ for 2025 is 45% 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 227.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,154 hours at sea against a median of 2,106 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2024 (6,840 t) and the lowest 2021 (2,882 t). Its efficiency percentile within the type went from 68 in 2021 to 49 in 2025 (lower is more efficient). Of the 7 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 656 of 1,348 qualifying chemical tankers by EEOI, at the 49th percentile. The dashed line is the type median, 14.4; this vessel reported 14.2.
EEOI divides emissions by transport work, which for this vessel and year was 214,057,082 tonne-miles over 13,359 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 5.4% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 55.6% while distance sailed fell 56.7%and CO₂ per nautical mile rose 2.6%.That points mainly to how much the vessel sailed, rather than the other.
