STI BRONX against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,735 gross tonnage it is larger than 82% 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 2019–2024 all give Majuro as port of registry.
Its 2,561 t of CO₂ for 2024 is 56% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 262.5 kg CO₂, close to the type median of 253.5 kg. It logged 859 hours at sea against a median of 2,177 hours for its type that year. 5.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 5 years with reported emissions, the highest was 2023 (12,397 t) and the lowest 2024 (2,561 t). Its efficiency percentile within the type went from 36 in 2019 to 8 in 2024 (lower is more efficient). Of the 5 comparable vessels listed below with a 2024 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 101 of 1,194 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 15.9; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 318,506,219 tonne-miles over 9,755 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 30.3% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions fell 79.3% while distance sailed fell 76.7%and CO₂ per nautical mile fell 11.4%.That points mainly to how much the vessel sailed, rather than the other.
