Road map towards Fit 55 and Net Zero 2050

EFACA project considers bespoke state of the art technological solutions for each of the following 4 aviation market segments: IAM (Innovative Air mobility), Regional Market, Medium-range Market and Long-range Market. It determines for each of them the most promising energy and technological solutions to achieve Net Zero objective in the shortest possible time.  This paper presents and assessment of possible EFACA pathways to achieve net-zero direct emissions from aviation, including changes 
and trade-offs in demand, energy efficiency, propulsion systems, alternative fuels for both passenger and freight transport and compensatory carbon removals.
