ELKA DELPHI 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 31,905 gross tonnage it is larger than 98% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2022–2025 all give Monrovia as port of registry.
Its 6,291 t of CO₂ for 2025 is 14% 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 310.9 kg CO₂, 24% above the type median of 250.2 kg. It logged 1,771 hours at sea against a median of 2,109 hours for its type that year. 12.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (15,471 t) and the lowest 2022 (990 t). Its efficiency percentile within the type went from 18 in 2022 to 13 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 177 of 1,348 qualifying chemical tankers by EEOI, at the 13th percentile. The dashed line is the type median, 14.4; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 753,441,916 tonne-miles over 20,235 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 535.6% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 59.3% while distance sailed fell 55.9%and CO₂ per nautical mile fell 7.7%.That points mainly to how much the vessel sailed, rather than the other.
