MISSISSIPPI STAR against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 92,752 gross tonnage it is larger than 100% 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 6,380 t of CO₂ for 2025 is 15% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 196.6 kg CO₂, 21% below the type median of 250.2 kg. It logged 3,497 hours at sea against a median of 2,106 hours for its type that year. 16.3% 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 (8,614 t) and the lowest 2024 (2,644 t). Its efficiency percentile within the type went from 83 in 2018 to 97 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,307 of 1,348 qualifying chemical tankers by EEOI, at the 97th percentile. The dashed line is the type median, 14.4; this vessel reported 49.1.
EEOI divides emissions by transport work, which for this vessel and year was 129,931,976 tonne-miles over 32,455 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 25.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 141.3% and CO₂ per nautical mile rose 13.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
