HURON 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 12,890 gross tonnage it is smaller than 65% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it RUBY-T for 2018–2022 and HURON for 2025. The reported port of registry changed: Valletta (2018–2022), then Majuro (2025).
Its 3,449 t of CO₂ for 2025 is 38% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 245.8 kg CO₂, close to the type median of 250.2 kg. It logged 1,238 hours at sea against a median of 2,109 hours for its type that year. 3.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (7,430 t) and the lowest 2022 (3,446 t). Its efficiency percentile within the type went from 82 in 2018 to 73 in 2025 (lower is more efficient). Of the 7 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 989 of 1,348 qualifying chemical tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 14.4; this vessel reported 22.2.
EEOI divides emissions by transport work, which for this vessel and year was 155,508,566 tonne-miles over 14,035 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 27.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 0.1% while distance sailed rose 14.5%and CO₂ per nautical mile fell 12.6%.
