EF EMMA against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 17,964 gross tonnage it is smaller than 78% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 61 other vessels here, 49 of them container ships. Columbia Shipmanagement is linked to 42 vessels on this register. The returns for 2018–2025 all give Madeira as port of registry.
Its 3,395 t of CO₂ for 2025 is 79% 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 338.5 kg CO₂, 38% below the type median of 545.6 kg. It logged 1,076 hours at sea against a median of 3,155 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2019 (16,390 t) and the lowest 2024 (2,070 t). Its efficiency percentile within the type went from 80 in 2018 to 81 in 2019 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 77.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 64.0% and CO₂ per nautical mile rose 6.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
