Une \u00e9tude men\u00e9e par la Cerema, le centre d'\u00e9tudes et d'expertise sur les risques, l'environnement, la mobilit\u00e9 et l'am\u00e9nagement, affirme que les voitures polluent davantage \u00e0 une vitesse moyenne de 30 km\/h que de 50 km\/h. <\/strong><\/p>\n

Tandis qu'une r\u00e9cente \u00e9tude vient de confirmer que les voitures \u00e9lectriques restent moins polluantes qu'une voiture diesel\/essence<\/a>, voil\u00e0 une autre analyse qui pourrait contrarier les plans d'Anne Hidalgo, la maire de Paris. En effet, le CEREMA, le centre d'\u00e9tudes et d'expertise sur les risques, l'environnement, la mobilit\u00e9 et l'am\u00e9nagement vient de publier un nouveau rapport.<\/p>\n

Il y est soutenu que les voitures polluent davantage lorsqu'elles roulent \u00e0 une vitesse moyenne de 30 km\/h plut\u00f4t qu'\u00e0 50 km\/h<\/strong>. “Pour les v\u00e9hicules l\u00e9gers comme pour les poids-lourds, les \u00e9missions sont importantes \u00e0 tr\u00e8s faible vitesse (jusqu'\u00e0 30 km\/h environ)”, <\/em>assure le rapport du CEREMA. Selon l'institution plac\u00e9 sous la tutelle du minist\u00e8re de la Transition \u00e9cologique et solidaire, un v\u00e9hicule \u00e9voluant \u00e0 une vitesse moyenne de 30 km\/h \u00e9met 195,6 grammes de CO2<\/strong>, contre 164,7 grammes \u00e0 30 km\/h. Soit une augmentation de 18,9 %.<\/strong><\/p>\n

Selon le CEREMA, la vitesse moyenne la moins polluante est de 70 km\/h concernant les \u00e9missions de particules fines, d'oxydes d'azote et dioxyde de carbone. \u0081\u00c0 l'inverse, rouler aux alentours des 10 km\/h se veut particuli\u00e8rement polluant : “Les situations de congestion du trafic routier sont tr\u00e8s p\u00e9nalisantes du point de vue de la qualit\u00e9 de l'air”, <\/em>assure l'institut.<\/p>\n
