KEY OPUS against its type
Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 42,999 gross tonnage it is larger than 68% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The same builder is recorded for 360 other vessels here, 303 of them bulk carriers. Its MRV returns name it KEY OPUS for 2018–2019 and YM OPUS for 2020–2025. The returns for 2018–2025 all give PANAMA as port of registry.
Its 4,039 t of CO₂ for 2025 is 25% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 263.8 kg CO₂, close to the type median of 260.7 kg. It logged 1,377 hours at sea against a median of 1,200 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2022 (10,244 t) and the lowest 2019 (851 t). Its efficiency percentile within the type went from 28 in 2018 to 26 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 831 of 3,241 qualifying bulk carriers by EEOI, at the 26th percentile. The dashed line is the type median, 7.6; this vessel reported 6.0.
EEOI divides emissions by transport work, which for this vessel and year was 675,494,983 tonne-miles over 15,310 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 13.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 36.9% and CO₂ per nautical mile fell 9.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
