BW MIA: CO₂ emissions 2018–2025

BW MIA against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,645 gross tonnage it is smaller than 75% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it BW MIA for 2018 and CHEM MIA for 2019–2025. The returns for 2019–2025 all give MONROVIA as port of registry.

Its 8,037 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 201.9 kg CO₂, 19% below the type median of 250.2 kg. It logged 3,921 hours at sea against a median of 2,106 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2021 (8,308 t) and the lowest 2018 (1,931 t). Its efficiency percentile within the type went from 75 in 2018 to 52 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 708 of 1,348 qualifying chemical tankers by EEOI, at the 52nd percentile. The dashed line is the type median, 14.4; this vessel reported 15.0.

EEOI divides emissions by transport work, which for this vessel and year was 535,091,878 tonne-miles over 39,809 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 316.2% higher than in 2018, for EU/EEA voyages only.

From 2023 to 2025, emissions rose 13.5% while distance sailed rose 25.6%and CO₂ per nautical mile fell 9.6%.That points mainly to how much the vessel sailed, rather than the other.
