SkyTeam has announced the winners of The Aviation Challenge 2025, recognising airlines that have delivered measurable sustainability improvements through collaboration, innovation and real-world operational change across global aviation.

For UK-based business travel programmes, the initiative highlights how airlines are reducing emissions, advancing Sustainable Aviation Fuel adoption and supporting more responsible business travel without compromising network performance or traveller experience.

KLM and Transavia have partnered with Elysian Aircraft and Conscious Aerospace to advance sustainable aviation through innovative battery-electric and hydrogen fuel cell technologies, marking a significant step toward greener business travel. These collaborations, focused on developing Elysian’s 90-passenger E9X electric aircraft and Conscious Aerospace’s hydrogen-powered Dash 8-300, aim to decarbonise aviation by integrating airline expertise into cutting-edge propulsion systems.
