Will 'sustainable' fuels transform air travel?

The air industry's plan to reach net zero by 2050 rests on using new "sustainable" fuels such as plants or used cooking oil. Will it work?

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 鈥� with these alternative fuels being the cornerstone of the strategy. However, there鈥檚 little SAF actually being produced, it, and it鈥檚 much more expensive than fossil fuels. Can the technologies really take off?

Climate Question host Graihagh Jackson investigates, with reporting from the 91热爆's Monica Miller in Malaysia and Singapore.
