MSC ALLEGRA against its type
It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The returns for 2021–2025 all give Monrovia as port of registry.
Its 91,084 t of CO₂ for 2025 is 5.6 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 1,163.0 kg CO₂, 2.1 times the type median of 545.6 kg. It logged 4,741 hours at sea against a median of 3,155 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2025 (91,084 t) and the lowest 2021 (10,690 t). Its efficiency percentile within the type went from 7 in 2021 to 21 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
