Dossier 55 – Decarbonising air transport by 2050: a question of energy

AAE Dossier n°55 develops the themes already addressed in its Opinion n°20. It analyses the situation of air transport in a predominantly international context, discusses credible technical progress in aviation over the coming decades, lists the various solutions for obtaining CO2-neutral fuels, and details the considerable challenge facing society to produce sufficient decarbonised energy for aviation and other uses.

In areas where there is still a great deal of uncertainty, it sets out the issues and outlines possible solutions.

Finally, from a viewpoint of sobriety, it looks at the possibilities and limits of moderating traffic growth in the more developed countries.
