As much as everyone enjoys flying abroad for their holidays, the cost of the climate impact might be making people think twice. So what can we do? Aside from paying to offset the carbon, the emergence of a new industry is hoping to change the way we fly. Sustainable aviation fuels (SAFs) or e-fuels are looking to replace traditional fuels as a much greener alternative, but there’s still a long way to go.

Host Eleanor Higgs spoke with Sophie Zienkiewicz and Alasdair Lumsden, co-founders of Carbon Neutral Fuels, to find out if it might be possible to replace the fuel in our airplanes, capture carbon from the world around us, and provide a carbon-neutral alternative when we take to the sky.
