STELLA THERESA against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. The returns for 2019–2025 all give Majuro as port of registry.
Its 7,347 t of CO₂ for 2025 is 33% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 156.5 kg CO₂, 37% below the type median of 250.2 kg. It logged 4,816 hours at sea against a median of 2,109 hours for its type that year. 5.8% 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 (8,863 t) and the lowest 2023 (4,881 t). Its efficiency percentile within the type went from 89 in 2019 to 82 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
