GREAT EPSILON against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,354 gross tonnage it is larger than 95% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The reported port of registry changed: Majuro (2020–2024), then Singapore (2025).
Its 9,629 t of CO₂ for 2025 is 1.7 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 307.1 kg CO₂, 23% above the type median of 250.2 kg. It logged 2,622 hours at sea against a median of 2,106 hours for its type that year. 9.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2024 (10,660 t) and the lowest 2021 (6,425 t). Its efficiency percentile within the type went from 100 in 2020 to 28 in 2025 (lower is more efficient). Of the 6 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 377 of 1,348 qualifying chemical tankers by EEOI, at the 28th percentile. The dashed line is the type median, 14.4; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 902,474,227 tonne-miles over 31,354 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.5% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 9.7% while distance sailed fell 8.0%and CO₂ per nautical mile fell 1.8%.That points mainly to how much the vessel sailed, rather than the other.
