Electric cars might pollute much more than gas powered or diesel-powered cars, according to new research.
The Norwegian University of Science and Technology study found greenhouse gas emissions rose dramatically if coal was used to produce the electricity.
Electric car factories also emitted more toxic waste than conventional car factories, their report in the Journal of Industrial Ecology said.
“The production phase of electric vehicles proved substantially more environmentally intensive,” the report said, comparing it to how petrol and diesel cars are made.
“The global warming potential from electric vehicle production is about twice that of conventional vehicles.”
In addition, producing batteries and electric motors requires a lot of toxic minerals such as nickel, copper and aluminium.
Hence, the acidification impact is much greater than that of conventional car production.
“Across the other impacts considered in the analysis including potential for effects related to acid rain, airborne particulate matter, smog, human toxicity, ecosystem toxicity and depletion of fossil fuel and mineral resources, electric vehicles consistently perform worse or on par with modern internal combustion engine vehicles, despite virtually zero direct emissions during operation,” according to Prof Stromman.
