Are biofuels worse for the climate than petrol and jet fuel?
John DeCicco, Professor Emeritus at University of Michigan, has been studying transport emissions & biofuels for decades. Alasdair asked him about the alarming findings of his research: liquid biofuels could be worse for the climate than fossil fuels.
Alasdair spoke Finlay Asher, founder of Safe Landing, about the reasons technological and market-based solutions to aviation emissions are not going to get us to net-zero, and what the sector should be doing instead.
