SILVER MANOORA 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 2020–2025 all give HONG KONG as port of registry.
Its 1,319 t of CO₂ for 2025 is 76% 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 378.4 kg CO₂, 1.5 times the type median of 250.2 kg. It logged 384 hours at sea against a median of 2,106 hours for its type that year. 16.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2022 (7,143 t) and the lowest 2025 (1,319 t). Its efficiency percentile within the type went from 4 in 2020 to 52 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 696 of 1,348 qualifying chemical tankers by EEOI, at the 52nd percentile. The dashed line is the type median, 14.4; this vessel reported 14.8.
EEOI divides emissions by transport work, which for this vessel and year was 89,051,317 tonne-miles over 3,485 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 75.5% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 36.2% while distance sailed fell 62.3%and CO₂ per nautical mile rose 69.2%.
