ASTELLA against its type
It is one of 15 chemical tankers here under the Netherlands flag, 0.6% of the 2,344 on the register. Its MRV returns name it BIT WAVE for 2022–2024 and ASTELLA for 2025. The returns for 2022–2025 all give Dordrecht as port of registry.
Its 7,135 t of CO₂ for 2025 is 29% 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 134.3 kg CO₂, 46% below the type median of 250.2 kg. It logged 4,719 hours at sea against a median of 2,109 hours for its type that year. 17.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (8,824 t) and the lowest 2022 (5,553 t). Its efficiency percentile within the type went from 95 in 2022 to 72 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 970 of 1,348 qualifying chemical tankers by EEOI, at the 72nd percentile. The dashed line is the type median, 14.4; this vessel reported 21.6.
EEOI divides emissions by transport work, which for this vessel and year was 330,916,512 tonne-miles over 53,136 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.5% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.1% while distance sailed fell 3.8%and CO₂ per nautical mile rose 0.8%.That points mainly to how much the vessel sailed, rather than the other.
