Anyone who has bought an electric car to protect the environment will be surprised by the plans of the European Union. It also includes emission requirements for electric cars.
These so-called Euro 7 requirements for vehicles concern the limits for particulate pollution, which is caused by tires and brakes. In two years, the European Commission will publish a report setting out the methods for measuring these emissions.
These requirements also apply to electric cars, whose tires generally wear out more because these cars have more pulling power and are often heavier on average than combustion engine cars. For the moment, these are proposals from the European Commission in response to various studies showing that tires and brakes cause a lot of particulate matter.
Microplastics
It affects particles down to 10 nanometers. These microscopic particles often enter the food chain as microplastics via surface waters and rivers. In Europe alone, this wear and tear releases half a million tons of microscopic particles into the environment, the researchers estimate. I’m already there filters have been developed which slow down the rubber particulatebut they still look clunky and not very aerodynamic.
The Euro 7 standard will come into force in 2025 and although all vans and cars must be electric from that year onwards, tires and brake discs continue to be a major contributor to these emissions. However, electric cars brake much less than cars with combustion engines because a lot of braking energy is recovered and therefore the brake discs wear less quickly.
