Will these subsidies and programs accomplish their objectives? And at what cost? A review of the literature finds few cost-benefit studies on these key questions.Įditor’s note: A corrected version of this report has been posted. For example, an executive order signed by California governor Jerry Brown in January requires 5 million ZEVs to be on the state’s roads and highways by 2030.
Several states also have mandated the sale of ZEVs. These subsidies include state and federal tax credits for purchasing ZEVs and programs to subsidize the installation of vehicle-charging infrastructure in businesses, households, and along highways. To effect this change, governments are spending billions of dollars to subsidize electric vehicles. The primary rationale is to reduce air pollution and carbon dioxide (CO2) emissions. Many claim that “zero-emissions vehicles” (ZEVs), especially battery-powered electric vehicles, should replace most, if not all, cars and trucks powered by gasoline-burning internal combustion engines.
