HORIZON DIAMOND 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 41,254 gross tonnage it is larger than 65% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 637 bulk carriers here under the Hong Kong flag, 7.8% of the 8,138 on the register. The same builder is recorded for 204 other vessels here, 70 of them bulk carriers. Its MRV returns name it NINGBO SEAL for 2018 and HORIZON DIAMOND for 2019–2025. The returns for 2018–2025 all give HONGKONG as port of registry.
Its 5,193 t of CO₂ for 2025 is 1.6 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 297.7 kg CO₂, 14% above the type median of 260.7 kg. It logged 1,562 hours at sea against a median of 1,200 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2020 (9,977 t) and the lowest 2019 (3,328 t). Its efficiency percentile within the type went from 80 in 2018 to 31 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 999 of 3,241 qualifying bulk carriers by EEOI, at the 31st percentile. The dashed line is the type median, 7.6; this vessel reported 6.3.
EEOI divides emissions by transport work, which for this vessel and year was 824,288,889 tonne-miles over 17,443 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 25.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 29.6% while distance sailed fell 24.0%and CO₂ per nautical mile fell 7.4%.That points mainly to how much the vessel sailed, rather than the other.
