Fleet renewal and SAF adoption helps Wizz Air cut carbon emissions intensity

Wizz Air has reported that its average carbon emissions for 2023 amounted to 51.5 grams per passenger/km, 6.8% lower than in 2022.
This represents the airline’s lowest ever average annual carbon intensity result recorded in one calendar year, underpinning its leadership in CO2 intensity reduction among competitor airlines.
As part of its sustainability strategy, Wizz Air partnered with two sustainable aviation fuel (SAF) producers in 2023 - Neste and Cepsa.
To further support SAF development, the airline made its first equity investment of £5 million (€5.8 million) in Firefly Green Fuels, a UK biofuel company, and participated in a $50 million (€46 million) investment in the US-based SAF start-up CleanJoule.
In May 2023, Wizz Air became the first airline in Hungary to commercially test SAF supply together with MOL, operating five flights from Budapest airport with a 35% SAF blend.
In February 2023, Wizz Air achieved its lowest ever reported carbon emissions per passenger/km for one month, which amounted to 48.9 grams, an 8.3% reduction compared to the same month of 2022.
Wizz Air is committed to further reducing its CO2 intensity by 25% by 2030. An integral element of the airline’s sustainability strategy is the renewal of its fleet. The airline has been continuously growing its fleet whilst replacing its older aircraft with the latest technology, adding 32 of the newest and most sustainable Airbus A321neo aircraft to the fleet last year.
