GT STAR against its type
Built in 2012, it is 2 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,571 gross tonnage it is smaller than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 17 other vessels here, 14 of them chemical tankers. Its MRV returns name it GT STAR for 2018–2022 and TG ARIES for 2023–2025. The reported port of registry changed: Panama (2018), then Manila (2019–2022), then PANAMA (2023–2025).
Its 9,755 t of CO₂ for 2025 is 1.8 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 227.4 kg CO₂, close to the type median of 250.2 kg. It logged 5,326 hours at sea against a median of 2,106 hours for its type that year. 4.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2025 (9,755 t) and the lowest 2021 (3,415 t). Its efficiency percentile within the type went from 59 in 2018 to 83 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,119 of 1,348 qualifying chemical tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 14.4; this vessel reported 29.0.
EEOI divides emissions by transport work, which for this vessel and year was 336,710,735 tonne-miles over 42,892 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 73.4% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 77.2% while distance sailed rose 69.1%and CO₂ per nautical mile rose 4.8%.That points mainly to how much the vessel sailed, rather than the other.
