SONGA RUBY against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,259 gross tonnage it is smaller than 79% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The returns for 2018–2025 all give Valletta as port of registry.

Its 10,582 t of CO₂ for 2025 is 1.9 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 309.6 kg CO₂, 24% above the type median of 250.2 kg. It logged 3,345 hours at sea against a median of 2,109 hours for its type that year. 19.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (25,064 t) and the lowest 2021 (8,393 t). Its efficiency percentile within the type went from 97 in 2018 to 87 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,169 of 1,348 qualifying chemical tankers by EEOI, at the 87th percentile. The dashed line is the type median, 14.4; this vessel reported 32.8.

EEOI divides emissions by transport work, which for this vessel and year was 322,831,300 tonne-miles over 34,182 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 10.9% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 0.9% while distance sailed fell 1.0%and CO₂ per nautical mile rose 1.9%.That points mainly to how efficiently it sailed, rather than the other.
