ALGOLUNA 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). At 11,889 gross tonnage it is smaller than 72% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 9 chemical tankers here under the Canada flag, 0.4% of the 2,344 on the register. The returns for 2018–2022 all give Valetta as port of registry.
Its 9,565 t of CO₂ for 2022 is 1.6 times the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 331.4 kg CO₂, 24% above the type median of 266.3 kg. It logged 2,622 hours at sea against a median of 1,995 hours for its type that year. 22.5% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 5 years with reported emissions, the highest was 2018 (11,038 t) and the lowest 2020 (9,245 t). Its efficiency percentile within the type went from 64 in 2018 to 90 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 1,209 of 1,334 qualifying chemical tankers by EEOI, at the 90th percentile. The dashed line is the type median, 15.7; this vessel reported 38.3.
EEOI divides emissions by transport work, which for this vessel and year was 249,937,288 tonne-miles over 28,867 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 13.3% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 11.4% while distance sailed fell 18.9%and CO₂ per nautical mile rose 9.1%.That points mainly to how much the vessel sailed, rather than the other.
