ARTEMIS LEADER: CO₂ emissions 2018–2025

ARTEMIS LEADER against its type

Built in 2008, it is the same age as the median vehicle carrier on this register (build year 2008, 595 vessels with a known build year). At 62,571 gross tonnage it is larger than 75% 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 102 other vessels here, 50 of them vehicle carriers. The reported port of registry changed: panama (2018–2019), then OMUTA (2021–2025).

Its 9,641 t of CO₂ for 2025 is 36% above the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 299.4 kg CO₂, close to the type median of 309.1 kg. It logged 2,221 hours at sea against a median of 1,639 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 5 years with reported emissions, the highest was 2025 (9,641 t) and the lowest 2019 (2,441 t). Its efficiency percentile within the type went from 37 in 2018 to 42 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 180 of 423 qualifying vehicle carriers by EEOI, at the 42nd percentile. The dashed line is the type median, 51.7; this vessel reported 47.4.

EEOI divides emissions by transport work, which for this vessel and year was 203,401,055 tonne-miles over 32,205 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 268.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions rose 105.8% while distance sailed rose 157.1%and CO₂ per nautical mile fell 19.9%.That points mainly to how much the vessel sailed, rather than the other.
