CARPE DIEM against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 17,800 gross tonnage it is smaller than 58% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. Its MRV returns name it CARPE DIEM II for 2024 and CARPE DIEM for 2025. The reported port of registry changed: Majuro (2024), then Valletta (2025).
Its 9,578 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 302.2 kg CO₂, 21% above the type median of 250.2 kg. It logged 2,825 hours at sea against a median of 2,106 hours for its type that year. 14.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 63 in 2024 to 91 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,232 of 1,348 qualifying chemical tankers by EEOI, at the 91st percentile. The dashed line is the type median, 14.4; this vessel reported 38.1.
EEOI divides emissions by transport work, which for this vessel and year was 251,382,152 tonne-miles over 31,695 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.4% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 34.4% while distance sailed fell 34.6%and CO₂ per nautical mile rose 0.3%.That points mainly to how much the vessel sailed, rather than the other.
