UNITY DISCOVERY: CO₂ emissions 2019–2025

UNITY DISCOVERY against its type

Built in 2017, it is 5 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 35,898 gross tonnage it is larger than 54% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 218 bulk carriers here under the Bahamas flag, 2.7% of the 8,138 on the register. The same builder is recorded for 77 other vessels here, 28 of them bulk carriers. The returns for 2019–2025 all give NASSAU as port of registry.

Its 2,091 t of CO₂ for 2025 is 35% 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 311.9 kg CO₂, 20% above the type median of 260.7 kg. It logged 705 hours at sea against a median of 1,200 hours for its type that year. 7.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2023 (5,013 t) and the lowest 2020 (448 t). Its efficiency percentile within the type went from 28 in 2019 to 35 in 2025 (lower is more efficient). Of the 2 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 1,135 of 3,241 qualifying bulk carriers by EEOI, at the 35th percentile. The dashed line is the type median, 7.6; this vessel reported 6.6.

EEOI divides emissions by transport work, which for this vessel and year was 317,268,589 tonne-miles over 6,704 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 186.9% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 41.3% while distance sailed fell 52.1%and CO₂ per nautical mile rose 22.4%.That points mainly to how much the vessel sailed, rather than the other.
