2. Could hydrogen-fuelled flights be a reality by 2035?

To achieve net-zero goals, aviation industry leaders are turning to alternative fuels, such as hydrogen, to reduce the industry's environmental footprint.

A new report by the World Economic Forum and the University of Cambridge’s Aviation Impact Accelerator explores how aviation can achieve a true zero climate impact.
