Manufacturing of Electric Vehicles and Carbon Emissions

Electric vehicles are more carbon-intensive to manufacture than traditional cars due to the production of batteries. However, the emissions occur mainly during the use of cars, with EVs emitting significantly less CO2 once in operation. It can take around 16,000 miles of driving to offset the emission debt from production, making EVs a more sustainable choice in the long run.
