JOLLY BLUE against its type
Built in 1999, it is 3 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 20,343 gross tonnage it is smaller than 55% of the other 269 ro-ro ships with a recorded tonnage. It is one of 16 ro-ro ships here under the Portugal flag, 5.1% of the 311 on the register. The same builder is recorded for 563 other vessels here, one of them a ro-ro ship. Messina Line is linked to 2 vessels on this register. The reported port of registry changed: Portugal (2020), then Madeira (2021–2025).
Its 18,447 t of CO₂ for 2025 is 14% 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 296.1 kg CO₂, close to the type median of 327.0 kg. It logged 5,099 hours at sea against a median of 4,872 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 6 years with reported emissions, the highest was 2022 (19,819 t) and the lowest 2020 (14,082 t). Its efficiency percentile within the type went from 38 in 2020 to 34 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 65 of 192 qualifying ro-ro ships by EEOI, at the 34th percentile. The dashed line is the type median, 85.3; this vessel reported 72.6.
EEOI divides emissions by transport work, which for this vessel and year was 254,092,838 tonne-miles over 62,292 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 31.0% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 4.7% while distance sailed rose 14.7%and CO₂ per nautical mile fell 8.8%.That points mainly to how much the vessel sailed, rather than the other.
