Dominique de Villepin relaunched Thursday a form of "bonus-malus" for the most polluting cars, announcing that the gray card would be "dependent on the polluting nature of the vehicles" from the 1er January.
The prime minister said that "for 8% of vehicles, this will represent a doubling of the amount of the gray card", while "for other vehicles, this measure will be neutral".
According to its services, only vehicles emitting more than 140 grams of CO2 per km will be taxed in addition to the current cost of the registration card: this will be only a "malus" for the most polluting vehicles, only time to purchase.
The 8% of the highest taxes raised by the Prime Minister are very large sedans, minivans and some most 4X4, which all emit more than 200 CO2 g per km.
"The biggest cars will be the most penalized, but this is not the heart of the offer of French manufacturers," said Thursday the chairman of the French Automobile Manufacturers Committee (CCFA) Manuel Gomez.
However, there would be no penalty or bonus for vehicles that emit fewer grams of 140 CO2 (20% of petrol vehicles and 40% of diesel vehicles registered in 2004).
