in 2017, a report made by ivl swedish environmental research institute also calculated that the co2 emissions of lithium-ion batteries (present in many electric cars today) are in the order of 150–200 kilos of carbon dioxide equivalents per kilowatt-hour battery. half of the co2 emissions (50%) comes from cell manufacturing, whereas mining and refining contributes only a small part of the co2 emissions. in practice, emissions in the order of 150–200 kilos of carbon dioxide equivalents per kilowatt-hour means that an electric car with a 100kwh battery will thus have emitted 15–20 tons of carbon dioxide even before the vehicle ignition is turned on. one of the authors, mats-ola larsson, reportedly said that this is the same amount of emissions as driving a gasoline car for 8,2 years. however, popular mechanics calculates that even if the 15–20 tons estimate is correct, it would only take 2.4 years of driving for the electric car with a 100kwh battery to recover the greenhouse emissions from the battery manufacturing. it however does not calculate in the emissions from battery replacements (battery replacement of regular lithium-ion batteries needs to be done every 2–3 years; lithium-ion batteries from cars typically last longer though). furthermore, two other studies suggest a 100kwh battery would generate about 6-6.4 tons of co2 emissions, so significantly less than what the ivl study claims.
