LYDERHORN against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it LYDERORN for 2021, LYDERHORN for 2022–2023 and SEA GULL for 2025. The reported port of registry changed: BERGEN (2021–2023), then MONROVIA (2025).
Its 2,382 t of CO₂ for 2025 is 57% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 214.9 kg CO₂, 14% below the type median of 250.2 kg. It logged 878 hours at sea against a median of 2,106 hours for its type that year. 6.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (10,008 t) and the lowest 2021 (2,125 t). Its efficiency percentile within the type went from 56 in 2021 to 75 in 2025 (lower is more efficient). Of the 2 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 1,016 of 1,348 qualifying chemical tankers by EEOI, at the 75th percentile. The dashed line is the type median, 14.4; this vessel reported 23.2.
EEOI divides emissions by transport work, which for this vessel and year was 102,432,258 tonne-miles over 11,082 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 12.1% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 76.2% while distance sailed fell 68.3%and CO₂ per nautical mile fell 25.0%.That points mainly to how much the vessel sailed, rather than the other.
