Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.
