STENA HIBERNIA against its type
Built in 1996, it is 6 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 13,017 gross tonnage it is smaller than 72% of the other 269 ro-ro ships with a recorded tonnage. It is one of 8 ro-ro ships here under the United Kingdom flag, 2.6% of the 311 on the register. The same builder is recorded for 7 other vessels here. The returns for 2018–2025 all give London as port of registry.
Its 973 t of CO₂ for 2025 is 95% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 557.3 kg CO₂, 1.7 times the type median of 327.0 kg. It logged 162 hours at sea against a median of 4,872 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 4 years with reported emissions, the highest was 2020 (26,070 t) and the lowest 2025 (973 t). Its efficiency percentile within the type went from 69 in 2019 to 76 in 2020 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 95.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions fell 96.3% and CO₂ per nautical mile rose 54.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
