GIANNA against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,006 gross tonnage it is larger than 89% 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. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it UACC SHAMS for 2018 and GIANNA for 2025.
Its 1,453 t of CO₂ for 2025 is 74% 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 723.5 kg CO₂, 2.9 times the type median of 250.2 kg. It logged 161 hours at sea against a median of 2,109 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 15 in 2018 to 71 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 952 of 1,348 qualifying chemical tankers by EEOI, at the 71st percentile. The dashed line is the type median, 14.4; this vessel reported 20.9.
EEOI divides emissions by transport work, which for this vessel and year was 69,350,835 tonne-miles over 2,008 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 65.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, 2024, so the series has gaps.
From 2018 to 2025, emissions fell 65.0% while distance sailed fell 83.4%and CO₂ per nautical mile rose 110.0%.
