ZIM SAN DIEGO: CO₂ emissions 2019–2025

ZIM SAN DIEGO against its type

Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 91,158 gross tonnage it is larger than 71% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 461 other vessels here, 155 of them container ships. Its MRV returns name it ZIM SAN DIEGO for 2019–2022 and SAN DIEGO for 2024–2025. The returns for 2019–2025 all give Monrovia as port of registry.

Its 20,964 t of CO₂ for 2025 is 28% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 845.8 kg CO₂, 1.6 times the type median of 545.6 kg. It logged 1,253 hours at sea against a median of 3,155 hours for its type that year. 0.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 36 in 2024 to 33 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 609 of 1,838 qualifying container ships by EEOI, at the 33rd percentile. The dashed line is the type median, 14.2; this vessel reported 10.5.

EEOI divides emissions by transport work, which for this vessel and year was 1,994,670,790 tonne-miles over 24,787 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 4.7% lower than in 2024, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions fell 4.7% while distance sailed fell 9.5%and CO₂ per nautical mile rose 5.3%.That points mainly to how much the vessel sailed, rather than the other.
