I travel abroad that I have postponed due to
Corona, and I go to the fort a lot by plane, and this aircraft is said to be the main culprit of greenhouse gases. That's why the European Union has made it mandatory for all flights from Europe to use a mix of conventional oil and green fuels from next year.

What kind of impact it will have on us, environmental reporter Jang Se-man interviewed.


Swedish environmental activist Thunberg and the famous British band Coldplay have one thing in common: they refuse to fly by plane.

This is because, in terms of carbon emissions, which is the climate crisis, airplanes are the overwhelming number one means of transportation.

[Thunberg/Swedish environmentalist: People act as if there is no climate crisis, even climate scientists and green politicians are flying around the world.]

In fact, the aviation industry accounts for 1% of global carbon emissions.

It would be nice to switch to an electric or hydrogen plane, but it is not easy due to the weight of the battery or the safety of the hydrogen tank.

For this reason, an alternative fuel has emerged as SAF, an alternative fuel called sustainable jet fuel.

Hydrocarbon fuels are obtained using vegetable raw materials such as rice husks and wood, or carbon dioxide and hydrogen captured in factories, and unlike petroleum, they are carbon-neutral fuels.

[Kim Jae-hoon, professor of mechanical engineering, Sungkyunkwan University: When we grow rice like rice husks, it absorbs CO2, which means that if we re-emitte it (as aviation fuel) as much as we absorb it, we can maintain carbon neutrality.]

The problem is that it is 2~2 times more expensive than the existing aviation fuel, and both the United States and Europe are greatly increasing support for the use of SAF in order to grow it into a new industry in the post-oil era.

On the other hand, it is the only Korean Air service in Korea that is used on the Paris-Incheon route, but there are no regulations in Korea, so it is only used for flights from Paris and not for flights from Incheon.

[Prof. Bae Chung-sik/KAIST Department of Mechanical Engineering: It was quite difficult for us to get ahead of ourselves, and there is a limit to what we can do while looking at the regulations and goals of Europe and the United States.]

It is pointed out that the existing export value of aviation fuel in Korea's oil refining industry is 3 trillion won per year, and the flow of changes in aviation fuel should not be missed in order to protect the market as well as the environment.
