Fossil-Free Aviation 2045 aims to create a long term national platform that brings together aviation stakeholders and acts in synergy with successful existing research and innovation environments. The initiative will help achieve the overarching goals agreed on by the Swedish aviation industry: that domestic aviation ends its reliance on fossil fuels by 2030 and that by 2045 no flights taking off from Swedish airports will use fossil fuels. The main purposes of the final report are to describe the actions that participants deem are needed during 2020–2045 to end the aviation industry’s dependence on fossil fuels, to convey the obstacles standing in the way of action, and to make recommendations to those who can remove these obstacles, mainly in terms of policy.
