GENCO CONSTELLATION 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 36,421 gross tonnage it is larger than 58% 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 same builder is recorded for 114 other vessels here, 111 of them bulk carriers. Its MRV returns name it SBI SAMSON for 2018–2019, NAVIGARE BELLUS for 2020 and GENCO CONSTELLATION for 2023–2025. The reported port of registry changed: Monrovia (2018–2019), then Majuro (2020–2025).
Its 248 t of CO₂ for 2025 is 92% 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 246.6 kg CO₂, close to the type median of 260.7 kg. It logged 91 hours at sea against a median of 1,200 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2020 (4,932 t) and the lowest 2025 (248 t). Its efficiency percentile within the type went from 28 in 2018 to 15 in 2023 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 93.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 82.0% and CO₂ per nautical mile fell 3.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
