Can someone quickly comment on the proposed (re)use of CO2 in making aviation fuel?

Major Japanese air carrier All Nippon Airways will begin developing fuel made from carbon dioxide in cooperation with several other firms.
The group, including Toshiba, Toyo Engineering and Idemitsu Kosan, aims to put the new fuel into practical use in the latter half of the 2020s. The group plans to produce the fuel by chemically treating CO2 emitted from factories and other sources through technologies owned by Toshiba and Toyo Engineering.
The developers will work to clear several challenges. They include fuel quality and profitability, and whether the fuel can be produced and supplied steadily. ANA started passenger flights using fuel made from food waste in November. The company says the CO2-derived fuel is expected to be able to reduce net emissions further. The aviation industry is in a difficult position on environmental issues, especially in Europe, as aircraft produce more CO2 emissions than trains and other transportation means.
Air carriers are rushing to take action as CO2 emission restrictions on international flights will be introduced next year.
And last year discussed in the BBC
