GIANCARLO D against its type
It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it GIANCARLO D for 2018–2022, NQ ACACIA for 2023 and TRISTAR NATASHA for 2024–2025. The reported port of registry changed: Valletta (2018–2023), then Majuro (2024–2025).
Its 6,433 t of CO₂ for 2025 is 16% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 230.2 kg CO₂, close to the type median of 250.2 kg. It logged 2,780 hours at sea against a median of 2,106 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (11,941 t) and the lowest 2019 (3,088 t). Its efficiency percentile within the type went from 67 in 2018 to 78 in 2025 (lower is more efficient). Of the 8 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 1,052 of 1,348 qualifying chemical tankers by EEOI, at the 78th percentile. The dashed line is the type median, 14.4; this vessel reported 25.0.
EEOI divides emissions by transport work, which for this vessel and year was 257,624,349 tonne-miles over 27,946 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 36.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 12.1% while distance sailed fell 9.2%and CO₂ per nautical mile fell 3.3%.That points mainly to how much the vessel sailed, rather than the other.
