BRENTHOLMEN 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 11,551 gross tonnage it is smaller than 77% 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. The returns for 2018–2025 all give Majuro as port of registry.
Its 8,010 t of CO₂ for 2025 is 45% 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 263.9 kg CO₂, close to the type median of 250.2 kg. It logged 2,734 hours at sea against a median of 2,106 hours for its type that year. 8.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2019 (12,861 t) and the lowest 2025 (8,010 t). Its efficiency percentile within the type went from 91 in 2019 to 96 in 2025 (lower is more efficient). Of the 2 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 1,301 of 1,348 qualifying chemical tankers by EEOI, at the 96th percentile. The dashed line is the type median, 14.4; this vessel reported 47.5.
EEOI divides emissions by transport work, which for this vessel and year was 168,674,037 tonne-miles over 30,354 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 13.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions fell 2.0% while distance sailed rose 1.4%and CO₂ per nautical mile fell 3.4%.That points mainly to how efficiently it sailed, rather than the other.
