ZIM RUBY against its type
It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The reported port of registry changed: HONG KONG (2024), then Singapore (2025).
Its 14,575 t of CO₂ for 2025 is 11% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 528.5 kg CO₂, close to the type median of 545.6 kg. It logged 1,609 hours at sea against a median of 3,155 hours for its type that year. 0.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 6 in 2024 to 18 in 2025 (lower is more efficient). Of the 6 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 335 of 1,838 qualifying container ships by EEOI, at the 18th percentile. The dashed line is the type median, 14.2; this vessel reported 8.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,810,563,975 tonne-miles over 27,578 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 154.6% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 154.6% while distance sailed rose 103.5%and CO₂ per nautical mile rose 25.1%.That points mainly to how much the vessel sailed, rather than the other.
