SOLAR RUBA against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2021–2024 all give MONROVIA as port of registry.
Its 7,411 t of CO₂ for 2024 is 27% above the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 254.4 kg CO₂, close to the type median of 253.5 kg. It logged 2,547 hours at sea against a median of 2,177 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2024 (7,411 t) and the lowest 2021 (3,690 t). Its efficiency percentile within the type went from 1 in 2021 to 6 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 78 of 1,194 qualifying chemical tankers by EEOI, at the 6th percentile. The dashed line is the type median, 15.9; this vessel reported 7.8.
EEOI divides emissions by transport work, which for this vessel and year was 956,314,839 tonne-miles over 29,127 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 100.8% higher than in 2021, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 2.4% while distance sailed fell 2.2%and CO₂ per nautical mile rose 4.7%.That points mainly to how efficiently it sailed, rather than the other.
