BOTTIGLIERI CHALLENGER against its type
Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 51,255 gross tonnage it is larger than 85% 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 211 other vessels here, 129 of them bulk carriers. Its MRV returns name it BOTTIGLIERI CHALLENGER for 2018 and W-PEARL for 2022–2025. The reported port of registry changed: Napoli (Italy) (2018), then Valletta (2022), then Monrovia (2024–2025).
Its 8,176 t of CO₂ for 2022 is 2.1 times the median of 3,908 t among the 3,902 bulk carriers on this register that reported for 2022. Per nautical mile it emitted 362.5 kg CO₂, 26% above the type median of 288.1 kg. It logged 2,618 hours at sea against a median of 1,254 hours for its type that year. 7.2% of its 2022 emissions were at berth; the median for bulk carriers was 4.2%. Its efficiency percentile within the type went from 72 in 2018 to 36 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 1,322 of 3,692 qualifying bulk carriers by EEOI, at the 36th percentile. The dashed line is the type median, 8.4; this vessel reported 7.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,110,896,739 tonne-miles over 22,556 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 23.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2023, so the series has gaps.
From 2018 to 2022, emissions fell 23.1% while distance sailed fell 15.9%and CO₂ per nautical mile fell 8.5%.That points mainly to how much the vessel sailed, rather than the other.
