GRAND ACE 5 against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,048 gross tonnage it is larger than 91% 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 GRAND ACE 5 for 2023 and SINO WISDOM for 2025. The returns for 2023–2025 all give Panama as port of registry.
Its 2,786 t of CO₂ for 2025 is 50% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 309.8 kg CO₂, 24% above the type median of 250.2 kg. It logged 771 hours at sea against a median of 2,109 hours for its type that year. 7.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 11 in 2023 to 14 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 184 of 1,348 qualifying chemical tankers by EEOI, at the 14th percentile. The dashed line is the type median, 14.4; this vessel reported 8.4.
EEOI divides emissions by transport work, which for this vessel and year was 330,045,024 tonne-miles over 8,993 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 56.2% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 56.2% while distance sailed fell 55.6%and CO₂ per nautical mile fell 1.4%.That points mainly to how much the vessel sailed, rather than the other.
