“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.”

  • Practical lessons in vehicle efficiency policy: The 10-year evolution of France's CO2-based bonus-malus (feebate) system

    Feebate systems can be an effective policy tool for promoting vehicle efficiency. A change that France made recently to its feebate system illustrates the absolute best way to do things, while a look back at what changed illustrates why alternatives are . . . not best.

    Newer is not always better. California’s ILUC analysis relies on stronger evidence on palm oil expansion than a new study from Argonne National Laboratory.

  • Soot-free buses and trucks for Mexico: Establishing the roadmap for Central and South America

    If the experience in Mexico is any indication, some manufacturers will likely look to weaken and delay the inevitable, rather than embracing and enacting cleaner standards that will make cities more livable, reduce climate pollution, generate tremendous social benefits, and most or all save many thousands of lives throughout the region.

  • Does it matter to your carbon footprint whether you're flying across the Atlantic or the Pacific?

    Two recent ICCT studies on the fuel efficiency of airlines revealed different gaps between the most and least efficient airlines operating transatlantic and transpacific routes. Could this be due to passenger load and frieght carrage?
