WHISTLER against its type

Built in 2007, it is 5 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 22,790 gross tonnage it is smaller than 84% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The reported port of registry changed: MONROVIA (2019–2022), then MAJURO (2023–2025).

Its 4,527 t of CO₂ for 2025 is 40% above the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 239.1 kg CO₂, close to the type median of 260.7 kg. It logged 1,801 hours at sea against a median of 1,199 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2020 (6,506 t) and the lowest 2024 (1,181 t). Its efficiency percentile within the type went from 96 in 2018 to 54 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,768 of 3,241 qualifying bulk carriers by EEOI, at the 54th percentile. The dashed line is the type median, 7.6; this vessel reported 7.9.

EEOI divides emissions by transport work, which for this vessel and year was 571,652,778 tonne-miles over 18,939 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 20.6% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 283.3% and CO₂ per nautical mile fell 4.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
