Air France-KLM launches first long-haul flight with eco-fuel 18 May, 2021 11:30 PM 3 minutes to read Other Air France-KLM sent into the air what the company called its first long-haul flight powered by sustainable aviation fuel - petroleum mixed with a synthetic jet fuel derived from waste cooking oils. The fuel used for the Paris-to-Montreal flight is part of efforts by the industry worldwide to experiment with alternative sources as regulators and governments tighten emissions rules for the coming decades. Other airlines and plane-makers are also experimenting with using varying levels of biofuels or different kinds of sustainable fuel. The passenger jet took off with sustainable fuel making up 16 per cent of its supply for the journey. Air France-KLM announced its initiative by the tarmac at Charles de Gaulle Airport in Paris. Joining France-KLM CEO Benjamin Smith at the event were Total oil company CEO Patrick Pouyanne and Airbus President Guillaume Faury.
