CL EMILY BRONTE against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2024–2025 all give MONROVIA as port of registry.
Its 5,516 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 277.9 kg CO₂, 11% above the type median of 250.2 kg. It logged 1,749 hours at sea against a median of 2,109 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 28 in 2024 to 17 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 225 of 1,348 qualifying chemical tankers by EEOI, at the 17th percentile. The dashed line is the type median, 14.4; this vessel reported 8.8.
EEOI divides emissions by transport work, which for this vessel and year was 627,547,213 tonne-miles over 19,850 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 39.5% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 39.5% while distance sailed fell 38.2%and CO₂ per nautical mile fell 2.1%.That points mainly to how much the vessel sailed, rather than the other.
