Electric vehicle saves environment-A myth or truth

How much CO2 is emitted in the production depends on where the lithium-ion battery is made — or specifically, how the electricity powering the factory is generated — according to Zeke Hausfather, a climate scientist and director of climate and energy at the Breakthrough Institute, an environmental research think tank.

Producing a 75 kilowatt-hour battery for a Tesla Model 3, considered on the larger end of batteries for electric vehicles, would result in the emission of 4,500 kilograms of CO2 if it was made at Tesla's battery factory in Nevada. That’s the emissions equivalent to driving a gas-powered sedan for 1.4 years, at a yearly average distance of 12,000 miles, Hausfather said..

If the battery were made in Asia, manufacturing it would produce 7,500 kg of carbon dioxide, or the equivalent of driving a gasoline-powered sedan for 2.4 years. Hausfather said the larger emission amount in Asia can be attributed to its "higher carbon electricity mix." The continent relies more on coal for energy production, while Tesla’s Nevada factory uses some solar energy.

A midsize vehicle completely negates the carbon dioxide its production emits by the time it travels 4,900 miles, according to the report. For full-size cars, it takes 19,000 miles of driving.


Electric vehicle is not 100% environment friendly unless it is used extensively. The vehicle should have a use more than 1,000 km per month and battery life should be more than 5 years.
