  1. >American Airlines, [Delta](https://news.delta.com/unlocking-potential-sustainable-aviation-fuel-through-meaningful-advocacy) and even Bill Gates think sustainable aviation fuel, produced from crops and organic waste, will help make flying green, but these fuels face a different problem. Analysis shows that to manufacture enough of this fuel to decarbonize aviation would require 30 percent of global farmland by 2050. We need that land [to feed people](https://www.nytimes.com/2024/12/13/opinion/food-agriculture-factory-farms-climate-change.html).

    Power-to-liquid and sun-to-liquid

    In future it will be possible to manufacture SAF using power-to-liquid and sun-to-liquid procedures. As the energy (electricity or heat) needed to do so will be generated from renewable sources and the carbon required will be drawn from the atmosphere, a ‘closed carbon cycle’ can be created in which the fuels manufactured are almost entirely carbon-neutral.
