KRITI RUBY against its type
It is one of 18 chemical tankers here under the Greece flag, 0.8% of the 2,344 on the register. The returns for 2019–2025 all give Piraeus as port of registry.
Its 11,869 t of CO₂ for 2025 is 2.1 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 381.7 kg CO₂, 1.5 times the type median of 250.2 kg. It logged 3,106 hours at sea against a median of 2,109 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2021 (13,940 t) and the lowest 2018 (7,360 t). Its efficiency percentile within the type went from 75 in 2018 to 66 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 892 of 1,348 qualifying chemical tankers by EEOI, at the 66th percentile. The dashed line is the type median, 14.4; this vessel reported 19.1.
EEOI divides emissions by transport work, which for this vessel and year was 620,454,260 tonne-miles over 31,095 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 61.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 19.5% while distance sailed fell 1.5%and CO₂ per nautical mile rose 21.3%.That points mainly to how efficiently it sailed, rather than the other.
