Air quality impacts of electric vehicles
The potential air quality impacts of electric vehicles in North Carolina are evaluated considering both air pollution reductions from less use of internal combustion engine vehicles and also additional air pollution at electric power plants. Using a consumer survey of 260 households, estimates of EV sales at $20,000 per vehicle, $15,000 and $10,000 are first made. EV purchases are classified as to whether they would be additional (new to family) or replacements of conventional cars. For additional vehicles, the extra pollution is computed as mileage driven, times KWH/mile, times power plant pollution rates. This pollution is then attributed directly to power plants, using NC pollution rates and the NC fuel mix. For replacement vehicles, EV pollution added to power plants is offset by direct pollution savings from ICE vahicles. Pollution effects are computed for each observation and displayed on a GIS of the state. Results show that EV air pollution effects are highly dependent on the assumptions made about the fraction of additional vs. replacement vehicles, and future power plant emission rates. The study concludes that EV effects on air pollution are highly uncertain.
