“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.”

  • Off the hook: Europe's current ZLEV proposal would allow CO2 emissions of new combustion engine vehicles to increase

    Even though targets for low- and zero-emission vehicles are an innovative approach for EU standards, they could undercut the climate benefit of the regulation. Fortunately, with some slight modifications EU regulators could effectively promote both fuel efficiency and electrification.
