NORDTAJO 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 25,546 gross tonnage it is smaller than 75% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 157 bulk carriers here under the Portugal flag, 1.9% of the 8,138 on the register. The same builder is recorded for 118 other vessels here, 105 of them bulk carriers. The reported port of registry changed: Valletta (2019–2020), then Madeira (2021–2025).
Its 2,764 t of CO₂ for 2025 is 15% 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 201.1 kg CO₂, 23% below the type median of 260.7 kg. It logged 1,278 hours at sea against a median of 1,200 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2019 (7,237 t) and the lowest 2020 (1,654 t). Its efficiency percentile within the type went from 44 in 2018 to 55 in 2025 (lower is more efficient). Of the 7 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 1,785 of 3,241 qualifying bulk carriers by EEOI, at the 55th percentile. The dashed line is the type median, 7.6; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 347,275,126 tonne-miles over 13,745 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 45.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 13.4% while distance sailed fell 11.2%and CO₂ per nautical mile fell 2.5%.That points mainly to how much the vessel sailed, rather than the other.
