Without SAF (Sustainable Aviation Fuels), there can be no growth in air transport; without e-SAF, there can be no future; but there can be no sustainable future without a parallel reduction in air traffic. Even up to 2040, by which time the expansion of these sustainable fuels will have significantly reduced emissions, but also after that. Even in the most optimistic scenarios, SAF production cannot increase fast enough or in large enough quantities to comply with the Paris Agreement. This, in a nutshell, is the conclusion of the report \"Being able to fly without oil\" produced by the A\u00e9ro D\u00e9carbo association in partnership with Jean-Marc Jancovici's think tank The Shift Project.<\/p>\r\n\r\n\r\n\r\n

With air traffic expected to grow at a rate of 3% per year worldwide over the next two decades, doubling in size by 2050, the conclusions of Aero D\u00e9carbo and the Shift Project are in line with those of ADEME, which, as early as 2022<\/a>, spoke of the need for moderation before SAF reaches cruising speed and the sector no longer relies essentially on fossil paraffin. According to this report, a worldwide reduction of at least 15 % in traffic over the next five years would be necessary to remain compatible with a climate trajectory limiting global warming to +1.7\u00b0C. In other words, a transitional return to 2010 levels.<\/p>\r\n\r\n\r\n\r\n

Reducing incentives to travel and advertising, limiting demand and controlling supply, reducing airport expansion, supporting alternatives such as rail: A\u00e9ro Decarbo and The Shift Project have put forward a number of solutions to accompany the reduction in traffic by travelling less often and less far.<\/p>\r\n\r\n\r\n\r\n
