DARNIA against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,906 gross tonnage it is larger than 97% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. Its MRV returns name it DVINA GULF for 2018–2022 and DARNIA for 2023–2025. The reported port of registry changed: Belize City (2018), then Panama (2019–2025).
Its 9,317 t of CO₂ for 2025 is 1.7 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 366.8 kg CO₂, 47% above the type median of 250.2 kg. It logged 2,326 hours at sea against a median of 2,106 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (12,360 t) and the lowest 2019 (4,482 t). Its efficiency percentile within the type went from 16 in 2018 to 34 in 2025 (lower is more efficient). Of the 3 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 463 of 1,348 qualifying chemical tankers by EEOI, at the 34th percentile. The dashed line is the type median, 14.4; this vessel reported 11.8.
EEOI divides emissions by transport work, which for this vessel and year was 790,255,301 tonne-miles over 25,400 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 14.1% while distance sailed fell 14.4%and CO₂ per nautical mile rose 0.4%.That points mainly to how much the vessel sailed, rather than the other.
