CAROLINE against its type
Built in 2002, it is 8 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 28,381 gross tonnage it is larger than 66% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it TORM CAROLINE for 2018–2019 and CAROLINE for 2023–2025. The returns for 2023–2025 all give Monrovia as port of registry.
Its 5,825 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 370.0 kg CO₂, 48% above the type median of 250.2 kg. It logged 1,410 hours at sea against a median of 2,106 hours for its type that year. 6.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (5,825 t) and the lowest 2023 (3,189 t). Its efficiency percentile within the type went from 16 in 2023 to 39 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 521 of 1,348 qualifying chemical tankers by EEOI, at the 39th percentile. The dashed line is the type median, 14.4; this vessel reported 12.4.
EEOI divides emissions by transport work, which for this vessel and year was 468,285,370 tonne-miles over 15,746 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 82.7% higher than in 2023, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 17.5% while distance sailed rose 25.8%and CO₂ per nautical mile fell 6.6%.That points mainly to how much the vessel sailed, rather than the other.
