Despite consistent, continued efforts by the aviation industry to reduce emissions, further technological advances are required to mitigate its impact on the global climate. This article first outlines aviation's importance in the global challenge and its specific constraints relative to other industries. It then investigates the current understanding of aviation's climate impact and the ongoing Rolls-Royce efforts to develop technologies to mitigate it. This includes improving the engine's propulsive efficiency, thermal efficiency, and combustion process. This article also discusses paradigm shifts that might redefine the way this industry operates in the global environment.
