ZAHRA against its type
It is one of 27 chemical tankers here under the Saudi Arabia flag, 1.2% of the 2,344 on the register. The returns for 2023–2025 all give Dammam as port of registry.
Its 3,779 t of CO₂ for 2025 is 32% 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 292.2 kg CO₂, 17% above the type median of 250.2 kg. It logged 1,100 hours at sea against a median of 2,109 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 3 in 2023 to 14 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 191 of 1,348 qualifying chemical tankers by EEOI, at the 14th percentile. The dashed line is the type median, 14.4; this vessel reported 8.5.
EEOI divides emissions by transport work, which for this vessel and year was 443,571,596 tonne-miles over 12,933 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 136.0% higher than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 136.0% while distance sailed rose 86.3%and CO₂ per nautical mile rose 26.7%.That points mainly to how much the vessel sailed, rather than the other.
