Will 'sustainable' fuels transform air travel?

The future of flying might depend on used cooking oil, plants and
green electricity. Sustainable aviation fuels, known as SAF, are
made from less carbon-intensive processes and renewable sources.
Airlines are touting them as the key to decarbonising flying.


The aviation industry has pledged to move from 2.5% of all global
CO2 emissions to net zero by 2050 – with these alternative fuels
being the cornerstone of the strategy. However, there’s little
SAF actually being produced, it, and it’s much more expensive
than fossil fuels. Can the technologies really take off?
