HARBOUR PIONEER against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). 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 11,391 t of CO₂ for 2025 is 2.1 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 271.7 kg CO₂, close to the type median of 250.2 kg. It logged 3,811 hours at sea against a median of 2,106 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2024 (11,530 t) and the lowest 2019 (2,670 t). Its efficiency percentile within the type went from 66 in 2018 to 79 in 2025 (lower is more efficient). Of the 7 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 1,061 of 1,348 qualifying chemical tankers by EEOI, at the 79th percentile. The dashed line is the type median, 14.4; this vessel reported 25.5.
EEOI divides emissions by transport work, which for this vessel and year was 447,414,376 tonne-miles over 41,921 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 140.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 1.2% while distance sailed fell 5.4%and CO₂ per nautical mile rose 4.5%.
