“These findings show that CO2 emissions from the new car fleet in Europe can be reduced even if the market share of diesel cars would continue to fall in future years. In fact, a transition from diesel cars to advanced gasoline technology and either hybrid or plug-in vehicles, including gasoline plug-in hybrid and battery electric vehicles, would reduce the net costs of complying with a hypothetical 70 g/km CO2 standard for 2025.”
