At 7,138 gross tonnage it is larger than 55% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. Its MRV returns name it TUNGOR for 2018–2019, KLAUS for 2020–2024 and LUCA for 2025. The reported port of registry changed: Monrovia (2018–2020), then Madeira (2021–2024).
Its 1,691 t of CO₂ for 2025 is 40% 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 145.4 kg CO₂, 19% above the type median of 122.2 kg. It logged 1,319 hours at sea against a median of 3,044 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2023 (5,252 t) and the lowest 2024 (645 t). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.
