Manufacturing Them Leaves Massive Carbon Footprint
Once in operation, electric cars certainly reduce your carbon footprint, but making the lithium-ion batteries could emit 74% more CO2 than for conventional cars. Just to build each car battery—weighing upwards of 500 kilograms (1,100 pounds) in size for sport-utility vehicles—would emit up to 74% more C02 than producing an efficient conventional car if it’s made in a factory powered by fossil fuels in a place like Germany, according to Berylls’ findings.
