New research from the Norwegian University of Science and Technology has called into question how efficient it is to produce electric vehicles (EV) around the world.
The report suggests EV production produces more toxic waste than conventional car production and the greenhouse gases necessary to generate the electricity to run the car increase greenhouse gases "dramatically". The entire life-cycle of the car was taken into account for the report.
The Journal of Industrial Energy report wasn't totally damning of the development of EVs, saying they still made sense "in some cases" dependent on whether the electricity powering the EV was developed from a sustainable source.
The report said: "It is counterproductive to promote electric vehicles in regions where electricity is primarily produced from lignite, coal or even heavy oil combustion."
Europe was highlighted as a good area for EV production as it does have access to other types of energy production.
