In the past, researchers believed that electric drive passenger vehicles (EDVs) could reduce emissions. Yet this latest study reveals that even a sharp increase in the use of EDVs by 2050 would not significantly reduce emissions of high-profile air pollutants such as carbon dioxide, sulfur dioxide or nitrogen oxides.
EDVs is a catch-all term that includes hybrid, plug-in hybrid and battery electric vehicles. These means of transportation have been touted as ways to help reduce emissions and curtail climate change. But it seems that they're not as effective as previously supposed.
