In 2007 France introduced the Reward-Penalty scheme for personal cars. The average CO2 emissions of new vehicles registered in France has decreased from 149 g CO2/km in late 2007 to 130 g CO2/km in the first half of 2010.

France introduced the Bonus-Malus (reward-penalty) system for personal cars in 2007 to remove older polluting vehicles from the road and encourage manufacturers to develop low-emission vehicles by guiding consumer choice. This system provides a subsidy to those who purchase a new car that emits less than 130 grams (g) of carbon dioxide (CO2) per kilometer (km), while imposing a penalty on those who buy a new car that emits over 160 g CO2/km. The amount of the reward and penalty depends on the amount of CO2 emitted by the car.
Average CO2 emissions of new vehicles registered in France has decreased from 149 g CO2/km in late 2007 to 130 g CO2/km in the first half of 2010. For the first half of 2010, 49.5% of new cars registered were eligible for a Bonus (<125gCo2/km), whereas vehicles submitted to a Malus (>155gCO2/km) represented 9.8% of the new cars registered. Increase in market opportunities for low-emission vehicles is expected.
