A recent study shows that electric cars not only eliminate exhaust emissions, but also generate less pollution from brakes, tires, and pavement. In total, they manage to reduce 38% of non-engine emissions compared to combustion cars.
Thanks to regenerative braking, electric cars emit 83% fewer particles from brake wear. This system recovers energy when decelerating, reducing the reliance on mechanical brakes and their residues.
Hybrids also show partial benefits, with reductions ranging from 10% to 66%, depending on the model. In the case of tires, although BEVs are somewhat heavier, their particles are less toxic to human health.
Despite the increased weight, electric car tires release particles that, for the most part, do not remain suspended in the air. This contrasts with brake dust, which does have a greater impact on urban air quality.
The benefits of electric cars.
Reduced Emissions, Better Urban Health
Even considering only friction emissions, electric cars remain significantly cleaner. And this is without taking into account the total elimination of polluting gases emitted by traditional cars.
However, the study emphasizes that the greatest environmental benefit comes from using the car less. Public transport, cycling, and walking have a more positive impact than any type of electrification.
A bus may seem more polluting, but by moving many people, it reduces the carbon footprint per passenger. Meanwhile, active mobility not only protects the planet, but also improves health and well-being.
The report recommends continuing to electrify urban transport, but without losing sight of city redesign. More durable materials, tires with less wear, and urban planning focused on pedestrians and cyclists are key to a sustainable future.
The Benefits of Electric Cars Beyond the Environment
Electric mobility is a vital but not sole piece in achieving cleaner, quieter, and healthier cities. Combined with sustainable mobility strategies, it can profoundly transform the air we breathe.
In addition to reducing air pollution and greenhouse gas emissions, electric cars offer significant economic benefits for their users. Their cost per kilometer is notably lower thanks to the lower price of electricity compared to fossil fuels, and they require less maintenance due to having fewer moving parts than internal combustion engines.
In terms of performance, electric vehicles provide faster and smoother acceleration thanks to the instant torque of their motors. Moreover, many models include advanced technology such as regenerative braking, driving assistance systems, and smart connectivity, enhancing the user experience and road safety.
They also promote greater energy independence, as they can be charged at home using renewable sources. This not only decreases dependence on imported oil but also drives the transition towards a more resilient and decentralized energy system.
