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

As we've pointed out in the past (for example, here and here), feebate systems can be an effective policy tool for promoting vehicle efficiency and reducing both fuel consumption and CO2 emissions....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...

Don't throw out California's ILUC factors yet

Soy biodiesel is generally understood to have high indirect land use change (ILUC) emissions.  For example, California assigns an ILUC factor of 29 gCO2e/MJ to biodiesel in its Low Carbon Fuel...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.
