Hannah Ritchie published an excellent two-part explainer on the reality of aviation emissions and how the sector can respond to the Climate Emergency. Part one looks at various demand scenarios coupled with action scenarios of varying degrees and methods of reduction. Part two investigates the current landscape of aviation biofuels and the scale at which it would need to increase to meet the different demand and reduction scenarios. In reality, demand will need to reduce first in order to curb emissions before scaled sustainable aviation fuel is ready.
