The National Association of State Energy Officials published a Plug-in Electric Vehicle (PEV) Policy Evaluation Rubric, which allows users to evaluate the strength and weaknesses of all PEV-related policies in a metro area. The rubric uses a scoring system from 0 to 100, with higher scores indicating policies that are stronger in advancing PEV deployment. The Rubric considers a number of variables including vehicle purchase incentives and available rebates.
