Verified methane measurements from MSC Cruises reinforce Brittany Ferries’ call for emissions reporting based on actual ship performance.
A Wärtsilä case study published on 16 September highlights methane slip of 1.67% on MSC WORLD EUROPA and 1.48% on MSC EURIBIA, against the 3.1% FuelEU Maritime default. Independent verification and flag state recognition allow MSC to use these measured values for reporting.
Brittany Ferries raised the issue in September 2025 after a year-long study recorded 1.57% methane slip on SALAMANCA. CEO Christophe Mathieu argued that regulatory assumptions overstated actual emissions and called for reporting based on measured data.
In March 2026, Bureau Veritas confirmed verification covering SALAMANCA, SANTOÑA, SAINT-MALO and GUILLAUME DE NORMANDIE, enabling measured methane values to replace defaults under MRV and FuelEU Maritime requirements.
