Study: Electric car battery production releases as much CO2 as driving for years on gas


The report shows that battery manufacturing leads to high emissions. For each kilowatt-hour of storage capacity in the battery, emissions of 150 to 200 kilograms of carbon dioxide are generated in the factory. The researchers have not studied the individual car brand batteries, just how they were produced or what electrical mix they used. But to understand the importance of battery size, two standard electric cars on the market, Nissan Leaf and Tesla Model S, have batteries of approximately 30 kWh and 100 kWh respectively.

Even before you buy the car, CO2 emissions equivalent to 5.3 tons and 17.5 tons, respectively, gets produced. The numbers can be difficult to put in context. By way of comparison, a trip for a person returning from Stockholm to New York by air emits more than 600 kilograms of CO2, according to the UN organization ICAO’s calculation model.

Another conclusion of the study is that about half the emissions come from producing the raw materials and the other half from the battery factory. The mining accounts for only a small proportion of between 10-20 percent.
