With a traction battery produced in China, does an electric vehicle emit less CO2 than a petrol or diesel vehicle produced and used in the European Union? This is the question Transport & Environment is trying to answer.
With the creation of a new tool, Transport & Environment, the European federation for transport and the environment, is trying to provide a clear answer to the question of the "cleanliness" of electric cars.
Towards the end of the controversy over the pollution of electric vehicles?
To create its tool, the federation founded in 1989 and currently led by Jeppel Juul, compiled all the recent data collected on electric vehicles, petrol and diesel.
A maximum of parameters are taken into account to provide a reliable response, including the process of manufacturing rare materials necessary for the design of electronics or batteries.
This is also where electric vehicles are the worst. The emissions produced for their manufacture are 30% higher than those induced by the construction of a thermal vehicle. However, this balance is largely compensated for in use.
A full life cycle assessment: manufacturing and rolling
To take into account all of the parameters, the tool calculates the life cycle of a vehicle over 225,000 km – which is not much considering the life of an electric motor and a battery pack. traction, which can cover more than 500,000 km, like the Tesla used as a hybrid bike in California.

Thanks to the tool, it is possible to realize that even an electric car equipped with a battery assembled in China and driving in Europe would be 22% cleaner than a diesel car and 28% cleaner than petrol. And this can even reach 80% for a vehicle assembled and used throughout its life cycle in the same country.
This tool is accessible on the Transport & Environment website.
A view of today and the possible evolution in 2030
The calculation also takes into account the evolution of energy sources in the context of Transport & Environment simulations, in order to estimate CO emissions2 in 2030. Lucien Mathieu, transport and eco-mobility analyst at Transport & Mobilité said: “ This tool puts an end to the myth that driving an electric car in Europe can be worse for the climate than a diesel vehicle or equivalent fuel. It is simply not true. The most recent data show that electric cars in the EU emit on average almost three times less CO2 "
It only remains to wait for the countries to mobilize to generalize the most virtuous renewable energies to drastically reduce CO emissions2 of our vehicles.
