When considering the amount of carbon and CO2 created from assembling lithium ion batteries, one firm thinks the difference could be «negligible». The firm, established in 2015, posted a blog entry entitled «Exploring Lithium-ion Electric Vehicles’ Carbon Footprint» this week, where they call into question a former ICE vs. Their analysis «details the tremendous amount of energy needed to manufacture a lithium-ion battery.» Because a typical EV is on average 50% heavier than a similar internal combustion engine, the analysis notes that the «embedded carbon» in an EV is therefore 20–50% more than an internal combustion engine.
This estimate appears to come from a 2019 Swedish Energy Agency report in which they reduce their carbon intensity by half compared with the year prior. The motivation for lowering their estimates was the use of «close to 100 percent fossil free energy which is not common yet, but likely will be in the future.» In other words, the cost and carbon-intensity of lithium-ion batteries is predicated on renewable energy which itself requires cheap and carbon-efficient lithium-ion batteries. «Even if The Wall Street Journal figures are accurate, we believe most investors still do not appreciate how little the magnitude of potential carbon savings from lithium-ion EVs is,» G&R writes.
