YM WELLNESS against its type
Built in 2015, it is 7 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 144,651 gross tonnage it is larger than 89% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. The reported port of registry changed: Hong Kong (2018–2023), then Singapore (2025).
Its 650 t of CO₂ for 2025 is 96% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 643.8 kg CO₂, 18% above the type median of 545.6 kg. It logged 113 hours at sea against a median of 3,155 hours for its type that year. 11.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2018 (72,056 t) and the lowest 2025 (650 t). Its efficiency percentile within the type went from 8 in 2018 to 1 in 2023 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 99.1% 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 86.7% and CO₂ per nautical mile rose 4.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
