SEIN SAPPHIRE against its type
It is one of 2 refrigerated cargo carriers here under the South Korea flag, 1.0% of the 202 on the register. Its MRV returns name it WATER PHOENIX for 2018–2024 and SEIN SAPPHIRE for 2025. The reported port of registry changed: Monrovia (2018–2019), then Willemstad (2020–2021), then Panama (2022–2024), then Jeju (2025).
Its 372 t of CO₂ for 2025 is 93% below the median of 5,190 t among the 111 refrigerated cargo carriers on this register that reported for 2025. Per nautical mile it emitted 204.5 kg CO₂, 22% below the type median of 260.9 kg. It logged 221 hours at sea against a median of 1,731 hours for its type that year. 10.7% of its 2025 emissions were at berth; the median for refrigerated cargo carriers was 3.8%. Across 8 years with reported emissions, the highest was 2020 (7,677 t) and the lowest 2025 (372 t). Its efficiency percentile within the type went from 91 in 2018 to 81 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 87.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 88.4% and CO₂ per nautical mile rose 10.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
