CELESTE I against its type
Built in 2003, it is 7 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,128 gross tonnage it is larger than 93% 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 TORM THYRA for 2018–2019 and CELESTE I for 2024–2025. The reported port of registry changed: Singapore (2018–2019), then Panama (2024–2025).
Its 4,971 t of CO₂ for 2025 is 10% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 376.7 kg CO₂, 1.5 times the type median of 250.2 kg. It logged 1,075 hours at sea against a median of 2,106 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 68 in 2024 to 57 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 773 of 1,348 qualifying chemical tankers by EEOI, at the 57th percentile. The dashed line is the type median, 14.4; this vessel reported 16.1.
EEOI divides emissions by transport work, which for this vessel and year was 309,327,318 tonne-miles over 13,196 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.2% lower than in 2024, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 49.2% while distance sailed fell 58.9%and CO₂ per nautical mile rose 23.8%.That points mainly to how much the vessel sailed, rather than the other.
