SOLAR RUO YUN 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 2021–2025 all give Monrovia as port of registry.
Its 9,253 t of CO₂ for 2025 is 1.7 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 258.6 kg CO₂, close to the type median of 250.2 kg. It logged 3,078 hours at sea against a median of 2,109 hours for its type that year. 8.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2025 (9,253 t) and the lowest 2021 (2,321 t). Its efficiency percentile within the type went from 0 in 2021 to 14 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 188 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 1,091,200,472 tonne-miles over 35,787 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 298.7% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 2.1% while distance sailed rose 8.9%and CO₂ per nautical mile fell 6.2%.
