KEY KNIGHT against its type
Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 43,013 gross tonnage it is larger than 69% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The same builder is recorded for 360 other vessels here, 303 of them bulk carriers. The reported port of registry changed: PANAMA (2018–2020), then MONROVIA (2021–2025).
Its 3,768 t of CO₂ for 2025 is 16% 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 244.0 kg CO₂, close to the type median of 260.7 kg. It logged 1,366 hours at sea against a median of 1,200 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2020 (7,058 t) and the lowest 2022 (2,075 t). Its efficiency percentile within the type went from 21 in 2018 to 24 in 2025 (lower is more efficient). Of the 3 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 773 of 3,241 qualifying bulk carriers by EEOI, at the 24th percentile. The dashed line is the type median, 7.6; this vessel reported 5.8.
EEOI divides emissions by transport work, which for this vessel and year was 644,023,932 tonne-miles over 15,440 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 9.7% while distance sailed fell 3.3%and CO₂ per nautical mile fell 6.6%.That points mainly to how efficiently it sailed, rather than the other.
