3、ORDThe aeronautics industry is facing increasing pressure to reduce its carbon footprint and mitigate its impact on the environment.Sustainable aviation fuels(SAFs)represent one major potential solution to this challenge,as they are seen as the main lever for decarbonization in the medium term due t

4、o the technological maturity of the production processes,allowing for a reduction in greenhouse gas(GHG)emissions around 53%(latest studies are expected a 65%contribution)by 2050 for the sector.However,their widespread adoption and commercialization require the careful consideration of various facto

5、rs,including feedstock availability,sustainability,social impacts,the economic and regulatory landscape,production process yield,and potential competition with other sectors.This study on SAF pathways aims to provide a comprehensive overview of the different feedstocks that could be used for SAF pro

6、duction,as well as the potential risks and opportunities associated with each.It analyzes the availability and sustainability of various feedstocks and assesses their suitability for use in SAF production.One of the key focuses of this study is to assess the potential competition between SAF feedsto
