The ARB staff's analysis indicates that electric vehicles (EVs) will provide significant air quality benefits in California. In fact, emission rates associated with an EV are much lower than emission rates from an ultra-low-emission vehicle (ULEV), the lowest emitting internal-combustion-engine (ICE)-powered vehicle required by the ARB in the future. When compared to a conventional vehicle on the road today, EVs provide substantially greater emission benefits. Furthermore, unlike a conventional vehicle, an EV will maintain very low emission rates over the entire life of the vehicle. In addition to the extremely low emissions associated with an EV, the overall efficiency of an EV is better than the overall efficiency of a gasoline-powered vehicle. Thus, the use of an EV rather than a conventional vehicle results in the use of less energy, decreasing the production of pollutants and providing greater environmental benefit. By 2010, the ARB's analysis indicates that the existing zero-emission vehicle mandate will result in a five percent decrease in the ozone-forming pollutant emissions from the light-duty fleet. In future years, as the fleet turns over, the emission reductions from the existing zero-emission vehicle requirements will approach ten percent. Should EVs become even more popular, resulting in an increase in the number of EVs sold, the emission reductions could meet or exceed ten percent by 2010 and beyond.
