HIGH NAVIGATOR against its type
Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,447 gross tonnage it is larger than 73% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 121 other vessels here, one of them a chemical tanker. The reported port of registry changed: PANAMA (2018–2022), then Monrovia (2025).
Its 1,824 t of CO₂ for 2025 is 67% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 263.4 kg CO₂, close to the type median of 250.2 kg. It logged 578 hours at sea against a median of 2,109 hours for its type that year. 8.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2022 (11,481 t) and the lowest 2021 (604 t). Its efficiency percentile within the type went from 3 in 2018 to 7 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 98 of 1,348 qualifying chemical tankers by EEOI, at the 7th percentile. The dashed line is the type median, 14.4; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 241,291,005 tonne-miles over 6,926 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 84.1% while distance sailed fell 84.1%and CO₂ per nautical mile fell 0.3%.That points mainly to how much the vessel sailed, rather than the other.
