Pollutionwatch: how smart braking could help cut electric car emissions

Extra battery weight of electric cars means ways must be found to cut particulate emissionsYou would think that battery electric cars, having no exhaust pipes, would emit less air pollution than diesel and petrol vehicles. A controversial study in 2016 said particle pollution from electric cars would be worse. Due to battery weight, electric cars are about 200-300kg heavier than comparable-size cars that burn oil-based fuel. More weight means more particle pollution from the wear of brakes, tyre
