By Eric A. TaubThe manufacturing and disposal of electric vehicles result in more greenhouse gases than nonelectric models, but that difference will eventually disappear altogether.
Studies have found that though it’s true that the production of a B.E.V. causes more pollution than a gasoline-powered counterpart, that greenhouse gas emission difference is erased as the vehicle is driven.Credit...Matt Williams
This article is part of our series on the Future of Transportation, which is exploring innovations and challenges that affect how we move about the world.
In the 19th century, major cities faced their own emissions problem: horse manure.
With horse-drawn carriages clogging major thoroughfares, cities were burdened with noxious, smelly manure that drew flies and spread disease.
The issue started to resolve itself as internal combustion engine cars grew in popularity at the beginning of the 20th century. Of course, that meant horses, slowly but inexorably, were replaced by vehicles emitting greenhouse gases.
Now, as battery electric vehicles, or B.E.V.s — marketed as a more environmentally friendly vehicular option — replace internal combustion engines, some skeptics are pointing out that they actually have a larger carbon footprint than nonelectric vehicles. That’s due to the manufacturing and disposal of B.E.V.s — specifically their batteries — as well as a reliance on coal to create the electricity that powers them.
