The password is sustainability, no matter what sector you are talking about, the need of a change of course on emissions & egrave; imperative and the world of aviation cannot be sure get out of this game. Although there is a lot of talk about new electric or hydrogen airplanes, & egrave; very likely we won't see many for a few years; to reduce cos & igrave; the impact of the entire sector comes to immediate relief the SAF, also known under the name of sustainable aviation fuel. An important agreement signed in the past few hours will see; 50 airlines engaged in its use, so as to replace at least 10% of normal kerosene by 2030.

It is an alternative fuel that has quickly become one of the most popular solutions; sustainable, it is in fact an element chemically very similar to the traditional one but with a double advantage: the composition and the emissions. The latter, in fact, thanks to SAF are reduced by up to 80% compared to the classic used by airlines. It is not necessary to extract it by altering the delicate balance of mother nature, the SAF & egrave; produced thanks to the recycling of food waste, used cooking oil, paper and other organic waste.

Of course it is not; so & igrave; simple to produce it, the costs are in fact much more; high compared to normal fuel, even two to eight times. Few people realize it and for this reason the price is also very high: in 2019, for example, they were produced all over the world & quot; only & quot; 200 thousand tons worldwide, or less than 0.1% of the 300 million tons used overall.

Here is an example of how SAF is produced according to Air BP

Among others, Delta Airlines, BP and Boeing, three giants in the sector that have committed themselves to spend more, have signed the commitment. to have at least a part of SAF available. Bisogner & agrave; obviously produce more; sustainable fuel, otherwise it will not arrive never at acceptable volumes. The goal is therefore to change gear in this respect, exactly as assured by Shell Aviation which by 2025 wants to build 2 million tons of SAF.

The sustainable fuel market, according to IATA, is now worth about $ 13 billion, well above the $ 2.5 billion of 2016, but the sector is; more and more; hungry and estimates even speak of a turnover of $ 30 billion in 2030. It will be; then the intervention of the various governments is fundamental so that incentives can be activated capable of making the SAF more and more; attractive to airlines.

Every sector must do its part and the aviation sector cannot do its part. certainly exempt, also because & eacute; the International Energy Agency estimates that the sector's impact on global greenhouse gas emissions will increase; in these years if nothing comes done, going from 2.5% share in 2019 to 3.5% in 2030.
