According to Bio Fuel Daily, Emirates managed to conduct a test flight on Monday, powering one of the two engines of the aircraft with 100% SAF.

This is an important achievement for the Middle Eastern company, which aims to cut its jet fuel usage by 50%.

Emirates officials have been implementing sustainable aviation fuel in their aircraft since 2017, but the recent feat was "the first in the Middle East and North Africa to be powered by 100 percent SAF in one of the plane's two engines."

Last week, Dubai-based Emirates managed to run a similar GE90 engine with 100% sustainable fuel in ground testing and now, the company was able to demonstrate that planes are able to function with 100% SAF.

Should more companies adopt this technology, aviation could become more sustainable before net-zero solutions for aircraft will be widely available.
