PARIS (Reuters) -- France wants to gradually phase out the use of diesel fuel for passenger cars and will put in place a system to identify the most polluting vehicles, Prime Minister Manuel Valls said.
Next year, the government will launch a car identification system that will rank vehicles by the amount of pollution they emit, Valls said. This will make it possible for local authorities to limit city access for the dirtiest cars.
"In France, we have long favored the diesel engine. This was a mistake, and we will progressively undo that, intelligently and pragmatically," Valls said.
About 80 percent of French motorists drive diesel-powered cars.
