DELPHINUS LEADER against its type

Built in 1998, it is 10 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 57,442 gross tonnage it is smaller than 64% of the other 571 vehicle carriers with a recorded tonnage. It is one of 89 vehicle carriers here under the Liberia flag, 12.5% of the 713 on the register. The same builder is recorded for 323 other vessels here, 27 of them vehicle carriers. The reported port of registry changed: TOKYO (2019–2022), then Monrovia (2025).

Its 4,833 t of CO₂ for 2025 is 32% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 284.7 kg CO₂, close to the type median of 309.1 kg. It logged 1,175 hours at sea against a median of 1,639 hours for its type that year. 1.3% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 5 years with reported emissions, the highest was 2019 (12,966 t) and the lowest 2022 (4,377 t). Its efficiency percentile within the type went from 53 in 2019 to 58 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 245 of 423 qualifying vehicle carriers by EEOI, at the 58th percentile. The dashed line is the type median, 51.7; this vessel reported 56.4.

Reported CO₂ in 2025 was 62.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions rose 10.4% while distance sailed rose 28.7%and CO₂ per nautical mile fell 14.2%.That points mainly to how much the vessel sailed, rather than the other.
