DEMA against its type

Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 23,985 gross tonnage it is smaller than 79% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. Its MRV returns name it FOUR DIAMOND for 2018–2020 and DEMA for 2022–2025. The reported port of registry changed: La Valletta (2018–2020), then BRIDGETOWN (2022–2023), then MAJURO (2024–2025).

Its 1,880 t of CO₂ for 2025 is 42% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 266.5 kg CO₂, close to the type median of 260.7 kg. It logged 669 hours at sea against a median of 1,200 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2018 (5,756 t) and the lowest 2025 (1,880 t). Its efficiency percentile within the type went from 2 in 2018 to 70 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,286 of 3,241 qualifying bulk carriers by EEOI, at the 70th percentile. The dashed line is the type median, 7.6; this vessel reported 9.2.

0255075100more efficientless efficientThis vessel: 70th percentile, EEOI 9.2

EEOI divides emissions by transport work, which for this vessel and year was 204,811,547 tonne-miles over 7,056 nautical miles.

Reported CO₂ by year

2018: 5,756 t20185,7562020: 2,807 t20202022: 5,451 t20222023: 3,663 t20232024: 2,686 t20242025: 1,880 t20251,880

Reported CO₂ in 2025 was 67.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, so the series has gaps.

From 2024 to 2025, emissions fell 30.0% while distance sailed fell 28.6%and CO₂ per nautical mile fell 1.9%.That points mainly to how much the vessel sailed, rather than the other.
