American drivers have felt the pain of rising gas prices in recent months. There’s evidence this may be fueling interest in greener ways of getting around. Electric vehicles can be cheaper to own and operate than internal combustion engine cars, and they offer considerable sustainability benefits. But, just how much better for the planet are EVs, really?
Quite a bit, at least from a carbon emissions standpoint. You’d be better off sending a brand-new gasoline-fueled car to the scrap heap and replacing it with an electric vehicle, keeping one more tailpipe off the road for good. That’s the surprising new finding from researchers at UC Santa Barbara and UC Santa Cruz who explored the carbon footprint trade-offs of vehicle trade-ins.
“Replacing an internal-combustion vehicle with a battery electric vehicle almost always reduces greenhouse gas emissions,” said Roland Geyer, a professor at UCSB’s Bren School of Environmental Science & Management, and co-author of the new study, published in the journal Science.
Now, of course, the research team doesn’t actually recommend scrapping a car you just bought. But for drivers who are already in the process of making a decision about future transportation, the research makes the sustainability case for EV ownership crystal clear.
“In some ways, I think this is really a definitive study about the carbon emissions benefits of EVs, because it shows that even in such an extreme scenario, the EV is still the obvious winner,” added UC Santa Cruz Environmental Studies Professor Elliott Campbell, lead author of the paper. “So if you’re someone who’s trying to decide whether or not to put money into keeping your gas car going, switching to an EV as soon as a financially viable opportunity comes up is absolutely the right thing to do for the environment.”
