While electric cars typically emit less CO₂, the savings are smaller than most imagine. Over a 150,000 km lifetime, the top-line Tesla S will emit about 13 tonnes of CO₂. But the production of its batteries alone will emit 14 tonnes, along with seven more from the rest of its production and eventual decommissioning.
Compare this with the diesel-powered, but similarly performing, Audi A7 Sportback, which uses about seven litres per 100km, so about 10,500 litres over its lifetime. This makes 26 tonnes of CO₂. The Audi will also emit slightly more than 7 tons in production and end-of-life. In total, the Tesla will emit 34 tonnes and the Audi 35. So over a decade, the Tesla will save the world 1.2 tonnes of CO₂.
Moving a 4000 lb vehicle down the road requires a certain amount of energy, and that energy has to come from somewhere. Likewise, building the vehicle and dealing with it after its useful life has ended requires energy. If that energy comes from carbon fuel burning plants then it's no different in terms of emissions than a vehicle that burns its fuel on board. The idea that electric cars have zero emissions is false. More than false, really, a lie. Because Elon Musk knows better, but he still depends on the falsehood of zero emissions to make sales.
Don't be fooled - Elon Musk's electric cars aren't about to save the planet
