How, and how effectively, different electric vehicle (EV) related policies will work is an immediate and important question for California as the state updates its EV policies. Adding urgency, Assembly Bill (AB) 615, which was signed by the Governor, requires the California Air Resources Board (CARB) to produce a report by December 2018 on related topics, in consultation with the University of California Institute of Transportation Studies (UC ITS). Senate Bill (SB) 498, also signed, also requires CARB reporting with somewhat different but overlapping topics. The need is to define the state of the research on policies to support EV deployment in a manner that is directly usable by California in updating policies. The specific need for CARB is material estimates of these factors (called out in AB 615): "impact of income caps, increased rebates for low-income consumers, and increased outreach on the electric vehicle market, as well as a quantification of emissions reductions attributable to the Clean Vehicle Rebate Project."

This white paper is one in a series summarizing recent research findings for the state of California. The topic of the series is evaluating the important components of electric vehicle adoption and its effects. The goals of these white papers are to: 1. Synthesize the best published and on-going research available on each topic; 2. Highlight important research gaps and propose areas for future research; 3. Provide the reader with a framework for understanding the various dimensions of each topic; 4. Make a clear link between research findings and policy implications, if possible; and 5. Be accessible to an informed and interested, but non-technical audience.

 Key words: electric vehicles, policy analysis, automobile ownership, market penetration, incentives, emissions, California
