HELIOS LEADER against its type
Built in 2009, it is 1 year newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 60,212 gross tonnage it is larger than 65% of the other 571 vehicle carriers with a recorded tonnage. It is one of 66 vehicle carriers here under the Japan flag, 9.3% of the 713 on the register. The same builder is recorded for 38 other vessels here, 17 of them vehicle carriers. The returns for 2023–2025 all give TOKYO as port of registry.
Its 1,172 t of CO₂ for 2025 is 83% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 278.8 kg CO₂, close to the type median of 309.1 kg. It logged 270 hours at sea against a median of 1,639 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 3 years with reported emissions, the highest was 2023 (5,595 t) and the lowest 2025 (1,172 t). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 79.1% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 62.9% and CO₂ per nautical mile rose 2.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
