YM WITNESS 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. Yang Ming Marine Transport Corporation is linked to 2 vessels on this register. The reported port of registry changed: Hong Kong (2018–2020), then Singapore (2025).

Its 1,547 t of CO₂ for 2025 is 91% 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 723.6 kg CO₂, 33% above the type median of 545.6 kg. It logged 196 hours at sea against a median of 3,155 hours for its type that year. 13.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2019 (78,063 t) and the lowest 2025 (1,547 t). Its efficiency percentile within the type went from 10 in 2018 to 14 in 2020 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 98.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.

From 2020 to 2025, emissions fell 93.6% and CO₂ per nautical mile fell 11.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
