CORAL ESSBERGER against its type
Built in 2012, it is 2 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,583 gross tonnage it is smaller than 92% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The returns for 2022–2025 all give Madeira as port of registry.
Its 9,046 t of CO₂ for 2025 is 1.6 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 198.7 kg CO₂, 21% below the type median of 250.2 kg. It logged 4,207 hours at sea against a median of 2,109 hours for its type that year. 9.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (9,594 t) and the lowest 2023 (8,876 t). Its efficiency percentile within the type went from 94 in 2022 to 98 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,315 of 1,348 qualifying chemical tankers by EEOI, at the 98th percentile. The dashed line is the type median, 14.4; this vessel reported 51.4.
EEOI divides emissions by transport work, which for this vessel and year was 175,990,662 tonne-miles over 45,523 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1.8% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 5.7% while distance sailed fell 1.7%and CO₂ per nautical mile fell 4.1%.That points mainly to how efficiently it sailed, rather than the other.
