New research shows that electric cars are not as green as we thought.
Despite some fluctuations, the world is gradually shifting to electric cars. Sales figures show that cars like the Tesla Model Y և Ford Mustang Mach-E are very popular.
Leaving aside technological advantages and efficiency, consumers like the idea that they are environmentally friendly, but according to a new Emissions Analytics report, battery-powered cars are not as green as we thought. Of course, these silent lightnings do not emit CO2 from their non-existent exhaust pipes, but their tires are a different story.
A comprehensive study has shown that the emissions of particulate matter from worn tires while driving everyday are 1850 times higher than the equivalent emissions. If you have not guessed yet, then the problem is the heavy batteries installed on electric cars, which greatly increase their mass, causing additional stress on the tires.
The study notes that the weight of about five hundred kilograms of battery can “lead to tire emissions, which, if equal, are almost 400 times higher than the actual tailings emissions.” However, it should be noted that with “proper non-aggressive handling” and restorative braking, tire wear emissions can be minimized.
At this point, we need to consider the difference between tire emissions and tailings emissions. The former, according to the study, immediately enter the soil-water, while the exhaust gases remain in the atmosphere for a longer time, sharply reducing the air quality.
The report is full of complicated details, but the conclusion is that electric cars can be just as dangerous as some cars with internal combustion engines. Of course, this is just one study, but if you’re interested in going into the technical details, it might help.
However, tire pollution is not a new problem that no one knew about. The world’s leading manufacturers have been developing environmentally friendly alternatives for quite some time. For example, Michelin e.Primacy is the world’s first carbon neutral tire (at least in production).
Goodyear tests biodegradable tires with restorative capabilities. In order not to be left out of the world trends, Continental presented a concept, which consists of 50% recyclable and renewable materials.
Of course, you may disagree with the results of the study, but it makes you think, lets you understand that we are still very far from real sustainable transport.
