However, electric cars have a far more intensive production process than either diesels or gas-powered vehicles have. As they’re made, the factories and different manufacturing processes that take place release 40% more CO2 during production than traditional vehicles.
The other derogatory mark on an electric vehicle’s eco-report card would be its battery, which, because of the sheer amount of chemically produced material it contains, also creates a lot of pollutants. Weighing in at a half-ton or more, these massive energy sources can make up to ⅓ of an electric vehicle’s weight. But despite these setbacks, electric cars are still the best choice, as they still aren’t as polluting as diesel engines.
