TONGALA against its type

Built in 2004, it is 4 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). 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 563 other vessels here, 243 of them container ships. The returns for 2022–2025 all give Monrovia as port of registry.

Its 22,748 t of CO₂ for 2025 is 39% 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 549.5 kg CO₂, close to the type median of 545.6 kg. It logged 3,391 hours at sea against a median of 3,155 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2025 (22,748 t) and the lowest 2022 (15,905 t). Its efficiency percentile within the type went from 67 in 2022 to 69 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,267 of 1,838 qualifying container ships by EEOI, at the 69th percentile. The dashed line is the type median, 14.2; this vessel reported 20.0.

EEOI divides emissions by transport work, which for this vessel and year was 1,135,135,230 tonne-miles over 41,399 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 43.0% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions rose 14.4% while distance sailed fell 2.4%and CO₂ per nautical mile rose 17.2%.That points mainly to how efficiently it sailed, rather than the other.
