CYGNI 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 8,995 gross tonnage it is smaller than 83% 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 FMT EFES for 2018–2024 and CYGNI for 2025. The returns for 2018–2025 all give Valletta as port of registry.

Its 5,999 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 166.0 kg CO₂, 34% below the type median of 250.2 kg. It logged 3,664 hours at sea against a median of 2,106 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2019 (7,311 t) and the lowest 2020 (3,567 t). Its efficiency percentile within the type went from 97 in 2018 to 72 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 972 of 1,348 qualifying chemical tankers by EEOI, at the 72nd percentile. The dashed line is the type median, 14.4; this vessel reported 21.6.

EEOI divides emissions by transport work, which for this vessel and year was 277,617,307 tonne-miles over 36,134 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 9.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 46.5% while distance sailed rose 60.2%and CO₂ per nautical mile fell 8.6%.That points mainly to how much the vessel sailed, rather than the other.
