BLUE WAVE HARMONY against its type
Built in 1991, it is 9 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 22,986 gross tonnage it is larger than 50% of the other 470 ro-pax ships with a recorded tonnage. It is one of 13 ro-pax ships here under the Panama flag, 2.6% of the 493 on the register. The same builder is recorded for 29 other vessels here, 15 of them ro-pax ships. P&O Ferries is linked to 10 vessels on this register. Its MRV returns name it EUROPEAN SEAWAY for 2018–2019 and BLUE WAVE HARMONY for 2024–2025. The reported port of registry changed: Dover (2018), then Limassol (2019), then PANAMA (2024–2025).
Its 1,268 t of CO₂ for 2025 is 96% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 566.7 kg CO₂, 21% above the type median of 467.6 kg. It logged 569 hours at sea against a median of 4,243 hours for its type that year. 0.6% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 4 years with reported emissions, the highest was 2018 (32,832 t) and the lowest 2025 (1,268 t). Of the 3 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 96.1% 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 fell 80.7% and CO₂ per nautical mile rose 21.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
