The mayor of Paris, Anne Hidalgo, has already announced plans to remove all diesel cars from the roads of the French capital by 2024. Now she's adding gasoline-powered vehicles to her list. Today, the Evening Standard reports that Parisian authorities announced plans to ban all combustion-engine cars, including those powered by gasoline, from the city's roads by the year 2030. Christophe Najdovski, one of Paris's transportation officials, told the radio station France Info, "Transport is one of the main greenhouse gas producers . . . so we are planning an exit from combustion engine vehicles, or fossil-energy vehicles, by 2030."
