DEMETER 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 61,804 gross tonnage it is larger than 72% 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 136 other vessels here, 36 of them vehicle carriers. The reported port of registry changed: Panama (2018), then Kumage (2019–2020), then Kaminoseki-cho (2023–2025).
Its 7,534 t of CO₂ for 2025 is close to the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 323.7 kg CO₂, close to the type median of 309.1 kg. It logged 1,701 hours at sea against a median of 1,639 hours for its type that year. 3.3% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 5 years with reported emissions, the highest was 2020 (13,540 t) and the lowest 2024 (1,345 t). Its efficiency percentile within the type went from 70 in 2019 to 49 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 206 of 423 qualifying vehicle carriers by EEOI, at the 49th percentile. The dashed line is the type median, 51.7; this vessel reported 50.8.
EEOI divides emissions by transport work, which for this vessel and year was 148,387,630 tonne-miles over 23,273 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 32.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 460.1% while distance sailed rose 398.8%and CO₂ per nautical mile rose 12.3%.That points mainly to how much the vessel sailed, rather than the other.
