L'administration Trump a finalis\u00e9 un assouplissement significatif des normes f\u00e9d\u00e9rales en mati\u00e8re d'\u00e9conomie de carburant pour les automobiles, remettant ainsi en cause une mesure cl\u00e9 qui avait incit\u00e9 le secteur \u00e0 am\u00e9liorer l'efficacit\u00e9 \u00e9nerg\u00e9tique des voitures et des camions et \u00e0 vendre davantage de v\u00e9hicules \u00e9lectriques \u00e0 batterie.<\/p>

Les constructeurs automobiles devraient atteindre une moyenne de 34,9 miles par gallon (mpg) pour leur parc de voitures et de camionnettes l\u00e9g\u00e8res de l'ann\u00e9e-mod\u00e8le 2031, a indiqu\u00e9 le minist\u00e8re des Transports dans un communiqu\u00e9. Ce chiffre est bien inf\u00e9rieur aux quelque 50 mpg exig\u00e9s par les normes adopt\u00e9es sous la pr\u00e9sidence de Joe Biden.<\/p>
