Global transport scenarios 2050. : rapport

76 pages
Au cours des quatre prochaines décennies, le transport mondial sera confronté à des défis sans précédent liés à la démographie, l'urbanisation, la réduction des émissions de gaz à effet de serre dans les villes, la congestion de trafic, l'augmentation de la demande de carburant.
A la lumière de ces défis et des niveaux d'incertitudes, ce rapport propose des scénarios de transport à l'horizon 2050.
