BALTIC SKY I against its type
Built in 2001, it is 9 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,235 gross tonnage it is larger than 50% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 29 chemical tankers here under the Türkiye flag, 1.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it BALTIC SKY I for 2018–2022 and ULUC KA for 2023–2025. The reported port of registry changed: Valletta (2018–2020), then Monrovia, Liberia (2021–2022), then İstanbul (2023–2025).
Its 5,286 t of CO₂ for 2024 is close to the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 324.8 kg CO₂, 28% above the type median of 253.5 kg. It logged 2,807 hours at sea against a median of 2,177 hours for its type that year. 9.3% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2019 (14,131 t) and the lowest 2023 (737 t). Its efficiency percentile within the type went from 82 in 2018 to 64 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 759 of 1,194 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 15.9; this vessel reported 19.9.
EEOI divides emissions by transport work, which for this vessel and year was 264,949,373 tonne-miles over 16,276 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 41.8% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 617.2% and CO₂ per nautical mile fell 32.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
