HARBOUR FIRST against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,971 gross tonnage it is smaller than 70% 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 2018–2025 all give Madeira as port of registry.
Its 10,866 t of CO₂ for 2025 is 2.0 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 252.6 kg CO₂, close to the type median of 250.2 kg. It logged 3,896 hours at sea against a median of 2,109 hours for its type that year. 6.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (12,795 t) and the lowest 2018 (4,960 t). Its efficiency percentile within the type went from 70 in 2018 to 78 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 1,058 of 1,348 qualifying chemical tankers by EEOI, at the 78th percentile. The dashed line is the type median, 14.4; this vessel reported 25.3.
EEOI divides emissions by transport work, which for this vessel and year was 429,497,233 tonne-miles over 43,018 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 119.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 9.8% while distance sailed rose 12.3%and CO₂ per nautical mile fell 2.2%.That points mainly to how much the vessel sailed, rather than the other.
