How much CO2 can electric cars really save compared to diesel and petrol cars? To answer this question we have developed a tool (see below) that compiles all the most up-to-date data on CO2 emissions linked to the use of an electric, diesel or petrol car.
We have taken into account all possible criteria such as the amount of CO2 emitted when electricity is produced or fuel is burnt, as well as the carbon impact of resource extraction for batteries or of building a power plant. We find out that electric cars in Europe emit, on average, more than 3 times less CO2 than equivalent petrol cars.
In the worst case scenario, an electric car with a battery produced in China and driven in Poland still emits 37% less CO2 than petrol. And in the best case scenario, an electric car with a battery produced in Sweden and driven in Sweden can emit 83% less than petrol.
