Per nautical mile it emitted 1,111.8 kg CO₂, 3.2 times the type median of 348.3 kg. It logged 4,722 hours at sea against a median of 3,550 hours for its type that year. 9.2% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.
