Abstract

Au niveau mondial, les transports consomment 20% de l'énergie, dont 80% dans les transports routiers et 10% dans les transports aériens, et 95% de cette énergie est à base de pétrole. Le secteur des transports est l'un des principaux émetteurs de gaz à effet de serre dans la plupart des pays, et notamment du CO2 issu de la combustion des carburants fossiles. Pour que les transports contribuent significativement à l'objectif du « Facteur 4 » en 2050, trois pistes différentes mais complémentaires peuvent être considérées : l'amélioration des technologies existantes, de nouveaux arrangements dans les services de transport, et enfin, les actions sur les comportements des usagers.
