DISCOVERER 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 20,924 gross tonnage it is smaller than 88% 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. The returns for 2018–2023 all give Majuro as port of registry.
Its 3,575 t of CO₂ for 2023 is close to the median of 3,386 t among the 3,573 bulk carriers on this register that reported for 2023. Per nautical mile it emitted 255.6 kg CO₂, close to the type median of 272.6 kg. It logged 1,750 hours at sea against a median of 1,186 hours for its type that year. 9.3% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Across 5 years with reported emissions, the highest was 2022 (4,510 t) and the lowest 2019 (1,513 t). Its efficiency percentile within the type went from 84 in 2018 to 91 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2023
Position 2,956 of 3,262 qualifying bulk carriers by EEOI, at the 91st percentile. The dashed line is the type median, 8.0; this vessel reported 14.1.
EEOI divides emissions by transport work, which for this vessel and year was 253,029,724 tonne-miles over 13,987 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 52.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2022 to 2023, emissions fell 20.7% while distance sailed fell 33.7%and CO₂ per nautical mile rose 19.6%.That points mainly to how much the vessel sailed, rather than the other.
