The agreement with oil, gas and chemicals company OMV gives the carrier the opportunity to purchase up to 185,000 metric tonnes of SAF.
The move comes as part of Wizz’s plans to reduce its CO2 intensity per passenger kilometre, as well as its goal to reduce its carbon emissions by 25% by 2030 and reach net zero by 2050.
Owain Jones, development officer at Wizz Air, said: "We have achieved our market-leading sustainability position by continued investment in innovative technology and operating the most up-to-date aircraft in the most efficient way.
"Wizz Air is committed to driving our emissions intensity down by a further 25% by the end of the decade, with the use of SAF playing a significant role in that commitment."
