ERRIA SWAN against its type
It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. The returns for 2018–2025 all give Middelfart as port of registry.
Its 156 t of CO₂ for 2025 is 97% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 196.9 kg CO₂, 21% below the type median of 250.2 kg. It logged 80 hours at sea against a median of 2,106 hours for its type that year. 24.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (6,964 t) and the lowest 2023 (111 t). Its efficiency percentile within the type went from 96 in 2018 to 76 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
