The concept of balancing the carbon footprint of an electric car depends on several factors, such as the energy source used to produce the electricity, the size of the battery, but also and mainly depending on the manufacturing process of the vehicle.
In general, electric cars tend to offset their carbon footprint more quickly than gasoline cars due to their energy efficiency, but also and above all in view of the absence of polluting emissions during their use.
However, you should know that producing an electric vehicle requires more energy and materials making up the batteries that must be extracted on the other side of the world.
50% more polluting emissions for the production of an electric car
If we had already asked ourselves the question of whether it was necessary to exchange our old diesel for an electric car, we are now wondering exactly how long it takes for the production of an electric vehicle to be profitable vis-à-vis -à vis its carbon footprint.
A question which requires taking into account several parameters, and which is the subject of new studies on this subject. According to figures from the Environment and Energy Management Agency (ADEME), the production of an electric vehicle represents 50% of polluting emissions additional in comparison with a thermal model.
The battery to be involved in the equation
A large part of the carbon footprint of an electric car comes from the manufacture of the battery, for which manufacturers are obliged to extract rare earths all over the world, in exploitations which are sometimes the cause of ecological scandals. Overall, there are currently three most common types of batteries, LFP, NMC and NCA.
They then contain nickel, manganese and cobalt, or nickel, cobalt and aluminum, while the more economical LFP batteries contain lithium, iron and phosphate. It should still be noted that as battery technology improves and production processes become more sustainable, the time required to offset the carbon footprint decreases .
How long does it take to offset the carbon footprint of an electric car?
Of course, an electric car will still have a better carbon footprint than a thermal model. The question is simple, once the vehicle is produced, it will have no polluting emissions compared to a thermal engine, which will pollute throughout its duration of use.
< p>According to Jarod Kelly, vehicle systems analyst engineer at the Argonne National Library, it is from 70,000 kilometers traveled with an electric car that the footprint carbon from its production is offset. We must therefore believe that the pollution generated by the creation of an electric car is even more amortized over the tens of thousands of kilometers it travels.
- From what mileage does an electric car offset its carbon footprint ?
- The production of an electric vehicle represents 50% additional pollutant emissions compared to a thermal model according to figures from Ademe.
- C’ ;it is from 70,000 kilometers that an electric vehicle compensates for the polluting emissions linked to its production.
