NAVIG8 CONSTELLATION against its type
It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The reported port of registry changed: Majuro (2018–2024), then Singapore (2025).
Its 5,072 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 435.7 kg CO₂, 1.7 times the type median of 250.2 kg. It logged 1,011 hours at sea against a median of 2,106 hours for its type that year. 14.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (13,946 t) and the lowest 2018 (3,409 t). Its efficiency percentile within the type went from 30 in 2018 to 35 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 475 of 1,348 qualifying chemical tankers by EEOI, at the 35th percentile. The dashed line is the type median, 14.4; this vessel reported 11.9.
EEOI divides emissions by transport work, which for this vessel and year was 424,457,741 tonne-miles over 11,643 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 48.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 36.7% while distance sailed rose 20.6%and CO₂ per nautical mile rose 13.3%.That points mainly to how much the vessel sailed, rather than the other.
