HOUYOSHI EXPRESS II against its type
It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The returns for 2018–2025 all give Panama as port of registry.
Its 437 t of CO₂ for 2020 is 93% below the median of 6,525 t among the 1,371 chemical tankers on this register that reported for 2020. Per nautical mile it emitted 319.9 kg CO₂, 19% above the type median of 269.8 kg. It logged 129 hours at sea against a median of 2,232 hours for its type that year. 25.6% of its 2020 emissions were at berth; the median for chemical tankers was 8.1%. Across 3 years with reported emissions, the highest was 2018 (11,374 t) and the lowest 2020 (437 t). Its efficiency percentile within the type went from 53 in 2018 to 55 in 2019 (lower is more efficient).
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Reported CO₂ by year
Reported CO₂ in 2020 was 96.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2019 to 2020, emissions fell 69.7% and CO₂ per nautical mile fell 5.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
