Science Alert:  Electric cars absolutely do produce less CO2 than gas guzzlers, a new study has confirmed countering claims that carbon emissions from the manufacture of electric cars and the production of electricity outweighed the savings on the road.  Crunching the numbers on data collected from 59 different regions in the world that represent 95 percent of the world’s transport and heating demand, researchers found that electric cars lead to an overall loss in CO2 output in the vast majority of places.  As electricity generation gets less carbon-intensive, the balance will tip away from petrol cars even further.  In countries like Sweden and France, where a lot of electricity is generated from renewables and nuclear, over their lifetimes electric cars can account for 70 percent less in terms of carbon emissions than petrol equivalents, when all the factors are included.The team also looked at the impact of electric heat pumps as a low-carbon option for home heating, and found they too were better for the environment overall, with electricity generation taken into account.
“The idea that electric vehicles or electric heat pumps could increase emissions is essentially a myth,” says environmental scientist Florian Knobloch, from Radboud University in the Netherlands.
“We’ve seen a lot of discussion about this recently, with lots of disinformation going around. Here is a definitive study that can dispel those myths. We have run the numbers for all around the world, looking at a whole range of cars and heating systems.”
