MAHADAH SILVER against its type
It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The returns for 2018–2025 all give Majuro as port of registry.
Its 1,092 t of CO₂ for 2025 is 80% 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 243.6 kg CO₂, close to the type median of 250.2 kg. It logged 389 hours at sea against a median of 2,106 hours for its type that year. 12.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2018 (9,927 t) and the lowest 2023 (16 t). Its efficiency percentile within the type went from 6 in 2018 to 7 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 101 of 1,348 qualifying chemical tankers by EEOI, at the 7th percentile. The dashed line is the type median, 14.4; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 143,438,896 tonne-miles over 4,481 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 89.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 82.6% while distance sailed fell 78.4%and CO₂ per nautical mile fell 19.8%.That points mainly to how much the vessel sailed, rather than the other.
