JOHANNA SCHULTE against its type

Built in 2013, it is 5 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 94,402 gross tonnage it is larger than 74% 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. Its MRV returns name it MSC ARBATAX for 2018–2019, JOHANNA SCHULTE for 2020–2022 and MSC DAKAR X for 2023–2025. The reported port of registry changed: Hong Kong (2018–2022), then Madeira (2023–2025).

Its 16,075 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 814.8 kg CO₂, 49% above the type median of 545.6 kg. It logged 1,259 hours at sea against a median of 3,155 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (51,778 t) and the lowest 2023 (5,491 t). Its efficiency percentile within the type went from 61 in 2018 to 64 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 67.7% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 15.0% while distance sailed fell 21.0%and CO₂ per nautical mile rose 7.7%.That points mainly to how much the vessel sailed, rather than the other.
