Methane slip remains a critical challenge in the adoption of LNG as a marine fuel, raising questions about its overall emissions footprint compared to other alternatives. Brittany Ferries, took part in a study in France to measure actual methane emissions from dual-fuel engines. By comparing these real-world measurements with the levels published by the IMO, the study provides valuable insights into the true environmental impact of LNG propulsion systems and offers a foundation for informed decision-making within the industry. This presentation will explore:

• What did the study reveal about methane slip levels from dual-fuel engines compared to IMO-reported figures?

• How do these findings impact the approach and urgency of methane abatement for the future of LNG in the industry?

• How can this data guide regulatory frameworks and inform future decarbonisation efforts?
