TANZANITE 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 32,987 gross tonnage it is smaller than 59% 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 118 other vessels here, 105 of them bulk carriers. The returns for 2019–2025 all give Monrovia as port of registry.
Its 10,117 t of CO₂ for 2024 is 3.0 times the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 303.3 kg CO₂, 15% above the type median of 264.0 kg. It logged 3,054 hours at sea against a median of 1,238 hours for its type that year. 3.4% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 5 years with reported emissions, the highest was 2024 (10,117 t) and the lowest 2019 (2,213 t). Its efficiency percentile within the type went from 69 in 2019 to 39 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 1,107 of 2,858 qualifying bulk carriers by EEOI, at the 39th percentile. The dashed line is the type median, 7.9; this vessel reported 7.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,418,964,937 tonne-miles over 33,354 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 357.2% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2023 to 2024, emissions rose 115.6% while distance sailed rose 110.1%and CO₂ per nautical mile rose 2.6%.That points mainly to how much the vessel sailed, rather than the other.
