The American Society for Testing and Materials International has approved a new jet fuel specification that will enable the use of alternative jet fuels in aviation.

The modified specification includes a 50/50 blend of synthetic paraffinic kerosene produced through the Fischer-Tropsch process.

The approval has been welcomed by the Air Transport Association of America (ATA) as well as the Aerospace Industries Association.

ATA president and CEO James C May said the passage of this specification is significant for all consumers of jet fuel.

“For the airline industry specifically, this brings us one step closer to our aim of widespread production of cleaner, alternative fuels that will help the industry meet its environmental goals while enhancing the security and competitiveness of its energy supply,” May said.

The approval will also make way for additional renewable fuels such as Bio-SPKs that aid in reducing the carbon footprint of the aviation sector.
