JOY LINE against its type
Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 9,556 gross tonnage it is larger than 63% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 23 general cargo ships here under the San Marino flag, 0.7% of the 3,081 on the register. The same builder is recorded for 127 other vessels here, 52 of them general cargo ships. Peter Döhle Schiffahrts-KG is linked to 65 vessels on this register. Its MRV returns name it LIBERTA for 2018–2022 and JOY LINE for 2024–2025. The reported port of registry changed: Saint John's (2019), then Panama (2020–2022), then BRIDGETOWN (2024), then san marino (2025).
Its 2,252 t of CO₂ for 2025 is 20% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 144.1 kg CO₂, 18% above the type median of 122.2 kg. It logged 1,532 hours at sea against a median of 3,044 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2021 (7,006 t) and the lowest 2025 (2,252 t). Its efficiency percentile within the type went from 68 in 2024 to 9 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 44 of 479 qualifying general cargo ships by EEOI, at the 9th percentile. The dashed line is the type median, 29.4; this vessel reported 14.7.
Across the 56 ranked vessels operated by Peter Döhle Schiffahrts-KG, the median percentile is 69. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 152,997,962 tonne-miles over 15,632 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 2.7% while distance sailed rose 80.0%and CO₂ per nautical mile fell 45.9%.That points mainly to how much the vessel sailed, rather than the other.
