Aston Martin is reviewing how a report was commissioned that has been criticized for making inaccurate comparisons of the climate harm caused by cars powered by batteries and combustion engines.
One claim it made was that it takes 78,000 km (48,000 miles) for EVs to be cleaner than conventional cars. The claim was widely reported by UK media outlets in the wake of Prime Minister Boris Johnson’s proposed 2030 ban on gasoline and diesel cars
The figure is more like 16,000 miles (25,750 km), according to Auke Hoekstra, a researcher at the Eindhoven University of Technology.
Hoekstra said the report underestimated emissions from combustion-engine cars by roughly half and did not take into account fuel production. It also bases its approximation of the carbon footprint of EVs on one model built by Polestar, the automaker jointly owned by Volvo Cars and Geely Holding Group.
Aston Martin CEO Tobias Moers said the report the company compiled along with some of its peers predated him joining the automaker in August.
