CAIFU CHAO 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 CENTRAL PARK for 2018–2022 and CAIFU CHAO for 2023–2025. The returns for 2018–2025 all give Monrovia as port of registry.
Its 1,509 t of CO₂ for 2025 is 73% 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 170.3 kg CO₂, 32% below the type median of 250.2 kg. It logged 698 hours at sea against a median of 2,106 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2018 (7,903 t) and the lowest 2025 (1,509 t). Its efficiency percentile within the type went from 0 in 2018 to 42 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 563 of 1,348 qualifying chemical tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 14.4; this vessel reported 13.0.
EEOI divides emissions by transport work, which for this vessel and year was 116,472,222 tonne-miles over 8,863 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 80.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 33.6% and CO₂ per nautical mile fell 24.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
