SkyTeam’s Sustainable Flight Challenge 2023 takes off, charting path to cleaner skies

More airlines, more flights, more innovations to help make flying greener

AMSTERDAM, 12 May 2023 – After months of innovating and ideating, the wait is over. Between 15 – 28 May 2023, 22 global airlines will take to the skies as part of SkyTeam’s second Sustainable Flight Challenge – a shared mission to discover new solutions to help make air travel greener. For a second consecutive year, the global airline alliance is harnessing the power of friendly competition and challenging airlines to operate their flights as sustainably as possible, above and below wing, from pushback to parking stand.

Launched in 2022, The Sustainable Flight Challenge (TSFC) is the industry’s first sustainability initiative of its kind and aims to affect meaningful change in the short-term. All participating airlines commit to sharing their innovations and insights industry-wide after the challenge to help reduce aviation’s environmental impact while the industry waits for greater availability of alternative fuel sources.

After last year’s inaugural challenge generated hundreds of new innovations, many of which are being adopted by our airlines, we’re excited to see what new ideas the second Sustainable Flight Challenge will bring our industry. A lot of hard work has gone into these dedicated flights and I am proud of the efforts these airlines are making in our mission to reduce emissions and find new ways to make air travel greener.
