Key Takeaways:

Rolls-Royce successfully completed tests of its Pearl 15 and Pearl 10X business aviation engines using 100% Sustainable Aviation Fuel (SAF).
The tests demonstrated SAF's compatibility and significant environmental benefits, including an 80% reduction in net carbon dioxide life cycle emissions and cleaner burning with lower particulate matter.
These successful trials are a key part of Rolls-Royce's strategy to achieve net-zero flight by 2050 and will help move SAF closer to certification for decarbonizing long-haul aviation.

Rolls-Royce said it successfully completed a series of tests of its Pearl 15 and Pearl 10X business aviation engines using 100 percent sustainable aviation fuel, or SAF.

The Pearl 15, which is the first member of the Pearl engine family, powers the Bombardier Global 5500 and 6500 aircraft. The Pearl 10X will be used on the Dassault Falcon 10X, the company’s ultralong-range flagship.
